* Getwork With LP support
* Stratum support is online!  Just use port 3333
* Support Ticket System for easy reporting of issues
* 1% Fee
* Detailed Stats
* Automatic Scheduled Withdrawals

* Once the pool is established reduce the number of confirmations required to payout a block (Faster Payouts) Done!
* Upgrade pool to take advantage of new improved code! Done!

To Connect :
1. Register an account then login & setup your workers : http://silverwolf.ath.cx/bbq/

2. Connect your miners as follows :
   url = http://silverwolf.ath.cx
   port = 3333 (Stratum) or 8342 (Getwork)
   username = <username>.<workername>
   password = <workerpassword>

3. Start Mining !

Just hit our first block !

Why don't you join us ?

The blocks are rolling in... Still need more miners though.

Come on in and stock up on BBQ while they are still easy to get won't you ?

Ok, guys here's an update.

The pool is doing well, we are up to 19 workers and 8.28MH/s, we are solving blocks every 17 minutes (Estimated).

Come one in and join the fun !!!

I thought I'd give bbq a try for a bit - I'm on board :)

sweet !   glad to have you with us!  ;D

To: our miners luciferase & slnet, you both have a very high stale percentage, your miner may be misconfigured. I would have emailed you except you did not provide your email address. Please check your settings and use the ticket system if you need help.

Fixed some bugs and we are still needing more miners.  Come on over guys !

FYI we are running a test tonight at 11pm central time to see if the system recovers properly from a failure of the bbqcoind client as it should.

Downtime is expected to be around 15 minutes, no data or shares are at risk of being lost.

Thank you for your understanding.

Auto-restart script test concluded successfully, if the bbqcoind client should crash (as it seems to do every few days), it will automatically recover in about 5 minutes.

issued a small bonus to active miners to reward them for coming back after the unexpected hour or so of downtime yesterday.

We will continue to do this as long as the pool has enough coins available to do so.  How much of a bonus depends on how long the downtime was and how much the pool has in reserve.

*** CONTEST CLOSED ***

Pool reserves are up to 815.  Keep those miners running guys!

Having some issues with server stability.  Will be migrating over to a new server Sunday evening.  Expected downtime Sunday will be about an hour. 

In the meantime, the server is back online now.

Reduced number of confirmations required for block payout to 30.  Faster payouts!!!

the bbqcoind process is very unstable still.  During the server migration tomorrow I am going to rebuild it from source and wipe it's database so it will rebuild the blockchain again from scratch.

This will take a few hours but it will hopefully result in a much more stable server.  The estimated down time is now approx 6 hours.  I am going to start Sunday at 3PM Central time so please plan on mining on a backup pool on Sunday from 3pm to approx 9pm Central.

I will post updates in this thread as the process continues.  Thank you.

Update on the contest progress.  It is still running, but some of our newest members aren't donating anything and this has slowed it down somewhat.  Rest assured that it is still running and as soon as the server's reserve balance hits 1,000 bbq coins I will make the payouts as planned.

I would appreciate any suggestions for future contests to do on the pool if anyone has any ideas.

Nobody ?  Come on guys!!!  Ideas for fun contests to do on the pool ?

Ok, server going down for upgrades now as planned.  Will post updates as time permits.

Award the longtime (i.e. more than one week) miner with the slowest hashrate.  :D

hmm.  interesting suggestion.

Do we have any others ?

Update on the upgrade process.  The new server is up and bbqcoind has been rebuilt from scratch.  It is downloading the blockchain now.

Once it has finished I will bring the server completely back online.

Thanks for your understanding!!

Now that's interesting ......  ;D

Ok, the new server is up and running, earlier than expected too.   Hopefully everything will be much smoother than before.  Please report any issues you experience using the ticket system ASAP!!!

Thanks Guys !

The pool's reserve balance is currently about 900 coins.  Won't be long now till we hit 1000 and the contest pays out.

How about we see what this new server can do ?

Also,

I'm looking for a better favicon.ico.  If anyone has any experience in creating them I would like to see your ideas.  I'm thinking of something like a silver coin with SW on it or maybe a wolf head, idk.  I'll leave the ideas up to you creative types.

I'd like a small version for the favicon.ico and a larger to use as a site logo on the main page.  I'm going to use the same logo & favicon on all of my pools, so it shouldn't pertain to any one particular coin.

I'm offering a 800 BBQ bounty (from my personal funds) to the person who submits the winning design.

Excellent !  Let me know if you have any issues.

It's set that way to accommodate slower miners.  If it becomes an issue than I will raise it.  At the moment it's a pretty good compromise until I can get vardiff implemented.

Is it an issue for you ?

Turn your scan rate down to 5.  That's where I run mine and I get less than 1% stales. (Edit my stale rate is actually at 1.01% now.)http://i41.tinypic.com/33atrsw.png

Also, stratum is coming next, that will drastically reduce stales as well.

If anyone is interested, I pasted my configure file for cgminer for my HD7950.  It works VERY well, I get @630 kh/s and very low stales.

http://pastebin.com/FE2866Hi

Let me know if changing the scan time helps you out.

So far so good on the new server.  I haven't received any support tickets and I've been watching it closely.

I do need to restart it to implement some performance tweaks.  I will do that tonight at approx 8PM Central time.

Downtime should be about 10 minutes.

Hmm, that's odd.  Well, after the server restart tonight the next thing on the agenda is stratum support. 

I have everything I need to implement it all lined up, I just need to work through getting it working and testing it.  Perhaps you can help me test it once I get it installed ?

Pool update : 91 blocks found from midnight to 11AM (Central)!!!  Rocking and Rolling!!

Edit: added post time to make it clearer how much time we are talking about here.

When the profitability of BBQ Coin finally rises to 122% people drop off the pool and now we are down to 6.79MH/s ?  What's up with that ?

Also, hint....  The contest is nearing completion. 

Ok, the contest has completed!  Here are the results (Sorted by overall hash rate at the moment):

That was pretty fun...  I'm going to do it again when the reserve balance hits 1,000 again, so KEEP MINING!!!

As previously announced the server will be restarted at 8pm Central (about an hour and a half) in order to apply some performance tweaks to the new server.

Downtime will be around 10 minutes so stick around!

Stratum support is now operational!

It's still in testing as far as reliability goes, but I have confirmed that shares are counted and found blocks are credited normally.

If you'd like to check it out use all the normal settings except use port 3333 instead of 8342 and you'll get stratum.

Please report any issues you find with it !!!!

Stratum support is now online.  Change your port to 3333 and give it a try.  Please let me know how it affects your stales.

I keep hearing stratum what is that mean?

It's a newer way for your miner to connect to the pool.  It's more efficient than the older getwork method and generally results in much fewer stales.

You can read more about it here : http://mining.bitcoin.cz/stratum-mining (http://mining.bitcoin.cz/stratum-mining)

I was getting 2.5% stales yesterday. Now with stratum it's down to .15%

Very nice!

Glad to hear it !  Thanks for letting me know.

Bad weather rolling through town.  Don't be too surprised if there is some unexpected downtime as a result.

Made some tweaks to MySQL to reduce diskio and server load.  Reduced server load by about 60% when lots of people are mining.

Just wanted to pop by and let you know that I am on board, and that this is the first time I have seen my name next to block found :) lol...

I wonder, do you fancy helping me tweak my miner a little? I have 2 7970's and I always struggle getting a good hashrate with script..

My current settings per card...

Msi ghz 7970

clock: 855
mem: 1500
guiminer: 7970 (low usage)
Threads: 2

Hashrate = 588

Powercolor non ghz

clock: 830
mem: 800
guiminer: 7970 (low usage)
threads: 2

Hashrate = 564

Windows 7, GUIscrypt alpha, 4gb of ram and an intel i5 cpu...

I can get a little more but I gotta crank everything right up and it doesn't seem worth the extra noise from the fans to get the little increase...

Also whenever I mine scrypt I see that I get loads of blocks on screen, but when I mine with bitminter client I don't get that and I get a better hashrate...

If you can help me out that would be great and as a thank you I will set my donation ;)

Please help cos I don't seem to find anything that works for me... :(

Well, the first thing you should probably do is switch to cgminer.  I mine with 7950's and I get 630 kh/s out of them so you should be able to do better than that with 7970's.

cgminer is not a gui program, it's command line but it's not all that difficult to get going.  

Here's the stuff you need:

1. Cgminer for windows : http://ck.kolivas.org/apps/cgminer/cgminer-3.1.1-windows.zip (http://ck.kolivas.org/apps/cgminer/cgminer-3.1.1-windows.zip)
2. My Config file, edit the username and passwords of course : https://docs.google.com/file/d/0B6PMWmOuapNud3NjajBjQzhBelk/edit?usp=sharing
3. My Batch file : https://docs.google.com/file/d/0B6PMWmOuapNuTzNuemtFTzcxZkU/edit?usp=sharing

Here's what to do:
1. Extract cgminer-3.1.1-windows.zip into a folder on your desktop.
2. Save the config file and batch file (#2 and #3 above) into the same folder where cgminer was extracted to.
3. Edit the cgminer.conf with notepad and enter your username.workername and password and save the changes.
4. Double click the batch file and see how it runs!

Now that you have it up and running with my settings, you need to learn what the settings are and how to tweak them yourself.  

Here's a tweaking guide written by the author of cgminer (If I remember correctly, I copied and pasted it) : https://docs.google.com/document/d/14JJOGkO2t6Oh9CtIsX1Tb5rMfKJsqygkgXDh-uk1D7g (https://docs.google.com/document/d/14JJOGkO2t6Oh9CtIsX1Tb5rMfKJsqygkgXDh-uk1D7g)

Here's the cgminer thread, scroll down and you can read about what each setting does : https://bitcointalk.org/index.php?topic=28402.0 (https://bitcointalk.org/index.php?topic=28402.0)

Let me know if you need anything else !

I didn't realize this pool was so small lol. Is the competition still open? If so maybe ill point my 850khash rig at it lol. do you guys think this coin has a future or should I just sell the coins I get?

Andy the coin just went onto Vircurex today :D

The contest is still running.  It is a small pool, but we solve about 140 blocks a day and really what more could you ask for from a pool ?  :)

If you'd like to join us we'd love to have you.

Also, I'd like to remind everyone that we do have stratum support working now.  You should consider switching over as it will reduce your stales.  ;D

To switch, just change the port from 8342 over to 3333.  Everything else stays the same.

Wolf, did you ever switch over to stratum ?  I think it will reduce your stales quite a bit.

Now that I've gone through 200,000 shares since stratum was enabled, I've got 620 stales, which represents 0.31%

If you're still over 5% there's gotta be something wrong with your configuration, or maybe even your network connection. How have you done on other pools in the past?

And our second run through the contest has completed !!!

Here are the results :


I think that's it for the time being.  Need more suggestions on other contests we could do.

That's a good idea !!

You could also proportion it by the amount of time spent actively contributing to the pool. To give the most loyal a little extra, you could also weigh it towards those who have the most hours. This could also discourage people from joining just for the contest and leaving right after.

I came up with this spreadsheet to demonstrate what I mean:

https://i.imgur.com/rzfaGt9.jpg

Hopefully that makes some sense to you.

Sorry for the super late reply but I have been really busy, I haven't had a chance to try out your advice silverwolf but thank you very much for giving me the links etc, when I get the time I will try them out. Thanks again. :)

I just got two credits into my account for 12.43750000 each. Was that a payment mistake or what?

My name is mfngimp

That's EXACTLY what I was suggesting.

Love the pool

Love the contest even more (especially since my computer is about as fast as a Commodore 64...and it takes me a week to get 1 BBQ Coin)

Fingers crossed-hoping I win

This pool is great, Im getting shares faster than any other pool that I have used prior

Hey fella, why not treat yourself to a 7950 or even a 7970? Take your computer to a whole new dimension, and hash some nice coins while you're at it! :)

Btw if you were part of the competition then you did "win" as the pot was split between us equally regardless of hashing power.

That may well change though, in fact not sure it is even still going...

I have still to set my donation (naughty me!) but I will do that right now while I remember...

Any way glad to have you on board and glad you are enjoying yourself. :)

And to silverwolf... Still haven't got round to doing that tweaking, grrrrrr, why do I never have any time when I need it! lol...

Any way donation is now set. :)

How about implimenting an indicator for the donators? As they do with other pools I have seen...

And I had another idea regarding the BBQ's... We need to start up a middle man service ala bitcoin. So that people can spend them, I think it would be a great boost for the coin and make it more profitable to mine. I am looking for people to join up with to start such a service... Would you be interested? Is there anyone that is interested?

I'll research that for you when I get into the office.

Lol, there was an issue while I was upgrading the FTC pool preparing to launch it.  It resulted in one FTC block being paid to the BBQ pool users (twice) because I missed changing one line in the script.  I've fixed it already, but since there was enough coins in the BBQ reserve to cover the payouts I just left them in place.

Call it a small bonus !

That's a good idea as well.  Let me think on it and I'll get started on the next contest shortly.

Wolf, here's what I found.  I pulled the information from the database for your userId for yesterday's date (05/23/2013)

During this time your hash rate varied a decent bit, and there was a period where you did not connect at all.  Here's the chart : http://i42.tinypic.com/2uhbz8j.png

Yesterday you submitted shares for 39 blocks here is the breakdown :

http://i40.tinypic.com/ezhgdy.png

I've uploaded the spreadsheet that contains the raw data if you'd like to review it.  You can download it here : https://docs.google.com/file/d/0B6PMWmOuapNuVEYtRng0enNLU0U/edit?usp=sharing

Based upon what I am seeing here I would have expected you to be paid about 204 coins for yesterdays work and you were actually paid a little over 208 coins yesterday.

It looks to me like you were paid correctly, I don't think you were aware that your miners were offline for approx 7 hours yesterday.  Take a look at the data (it's in LibreOffice format) and let me know if you need anything else or if you see anything here that I've missed.

Thanks.

Anytime man.  Your internet may have gone down for a while.  I know that mine does that on occasion.  They can be frustratingly unreliable sometimes.

The previous contest ended.  I will be planning the next one shortly though!  Stick around.

That's the reason we keep the share difficulty at 15 - 16, so that slower miners can get a fair shake at accepted shares.  It also increases the load on the server so I have to keep the pool fairly small until such time as I can get Vardiff implemented. 

Unfortunately, Vardiff requires SERIOUS modification to all of the existing code which is why it's not implemented yet. 

Frankly I'd rather have smallish pools anyhow, it's easier to keep up with, you get to know the miners better, and it's better for the coin (any coin really) to have lots of small pools instead of only a few really large ones.  Options are a good thing.

Im one of those small miners (laptop which i can only run at night) i can't thank-you enough for your pool. Yours is the only one that gets me some good coin. Keep up the great work!

Well thank you !  I'm glad you like it !

I joined this pool today.  This is about the 4th or 5th pool I've tried, hopefully I'll have better luck with this one.

What problems have you been having ?

Payouts were nowhere near what they were supposed to be on the other pools, even after mining for 2-3 days straight.  I've already earned almost as much mining for 8 hrs. here that I did mining for 24 hrs. at the last pool I tried lol.

This pool is great, please keep up the good work :).

Hey there, finally got down to sorting my cards out and I think they are doing okay now... Can I just post my stats and ask you to look over them for me incase something is no good...

cgminer with 2 7970's

Clock 950
Mem 1680 (it hasn't crashed but wondering if I may cause damage?)
fan speed 75%
Temps 75

Hashrate 666 (dun dun duuuuun) when pc not in use and 640 ish when in use...

card 2

clock 990
mem 1664
fan speed 65%
temps 76

Hashrate 692

This seems to be the best and most stable I can get it... I have no pci risers yet else I'm sure I could get those temps down some or even eek a little more out of the cards.

I am getting some artifacting on screen with firefox but movies and such play fine.

Do you think this is okay to leave for long periods?

If anyone would like to know more about how I got this please ask. :)

If you are getting artifacts you might want to turn the mem speed down a bit.  Other than that it looks pretty good to me.

Okay cool, thing is I have always gotten artifacts while I'm mining, no matter which miner I use, youtube vids won't play properly either, the picture keeps freezing... Do you think more ram could solve this? I only have 4gb of system ram at the moment and I see from the task manager that I only have a small ammount free, although it says I am using 46% or something, still don't get that. Does that take into account virtual memory or something?

Is there a way to turn the intensity down within cgminer or does it have to be done in the conf/.bat file?

Also how come I can change a conf to a txt and then edit it but I can't change a .bat and do the same... Is there a way to edit a .bat?

Oh and yeah I was gonna say, turning the mem speed down wouldn't do anything surely? Because no matter what I set the mem speed to cgminer will use it to it's fullest right? Leaving no room for anything else, only thing you could do is turn the intesity down? I used to do that in guiminer when I watched a film as I used to get screen tearing and artifacts. Turning the intensity down solved that.

With cgminer though I no longer get any problems with video playback, except for online videos.

I saw a thread before about using on board graphics for running the OS/GUI, do you know if that is possible? I believe there was something you could possibly do in the bios though I'm not sure.

To our miner "byltz", there is something wrong with your configuration.  You are getting 74% stales/invalids.

Check your settings.

When running cgminer, press G to change the gpu settings.  You can try different settings here before typing them into the configure file.  They will take effect as soon as you change them but will be not be saved.

The memory speed will certainly make a difference.  Cgminer will run it at whatever speed you set it at, too fast and you'll get artifacts, rejects, or crashes.

running your desktop off the built in graphics and just using the cards to mine is possible, but it's sometimes hard to get working properly.

you can edit a bat file by right clicking it and choosing "Edit" from the menu.

There are many things which can effect payouts, but after a day or so you should be getting your full payouts regardless of where you are mining if it's PPLNS.

The other pools you tried may not have fixed the bugs in the mmcFE payout logic, it's a real pain to get it right but if you don't, you'll end up overpaying some users and underpaying others.

How's my pool working out for you so far ?

Silly me, didn't see the intensity option before! doh! lol...

Well just had a play with both intensity (going down to 10) and mem clock speeds (going down to 1300) on the main gpu (display gpu) and nothing helps, the videos still jerk and such. The sound plays okay but image freezes and jerks. Just checked I have the latest flash and I do... As a control I disabled the gpu and youtube ran fine...

This is very odd, I have not come across this problem before. The only thing I can think is a ram issue or maybe a driver issue. Grrrrrr, well I will have to live with it I guess, I so want to get a dedicated miner! lol... One day, cheers for your help any way.

So far the pool is great!  Earning what I'm supposed to be earning, low % of stales, everything is running smoothly.

Glad to hear it !

Ok,

I know you guys haven't heard much from me lately.  That's because I've been busy.  After all the launch problems with the PWC pool I've been working hard at getting a stable set of base code that has all or nearly all the bugs worked out that is easy to deploy pools for new coins that includes the newest performance improvements and bug fixes.

Aside from a few performance issues the BBQ pool is doing GREAT! (stats page load times, anyone ?) so I'm not going to touch it until the new code base is 100% ready so don't worry.

The new code base has reached BETA status and I'm currently testing it on WDC (Worldcoin).  It needs more testing and more bug fixes I'm sure, but it's made it out of private alpha testing and so far everything is working well.

if any of you guys want to help me stabilize this code head on over to http://silverwolf.ath.cx/wdc register and throw some miners at it for a while.  Please report any issues (anything at all).

Once this base is stable, I will be deploying it to all of my pools and using it for any future pools.  I would like to have them all on the same code base.

Most of the improvements are behind the scenes, but you will notice increased performance, some changes to the stats and charts and other small changes to the interface.

I left the pool today... The guy/guys (?) over at BBQ.org are proper fools! They refuse to listen to any advice from anyone and are not welcoming at all... These cryptocoins are all about the community, why would you treat the community like crap? Especially when the coin is struggling as it is!

Any way, it is a waste of time to be honest and the price just keeps tanking, shame really cos it could have been good! Oh well, back to the old faithful for me.

Good luck with your pool, hope it picks up and I hope the guys at BBQ.org can pull their heads out of their arse! lol

Hmm well I'm sorry you had trouble with them.  Have you considered our Worldcoin pool ?  The WDC guys seem pretty friendly.

http://silverwolf.ath.cx/wdc

Profitability is at 103.77% at the moment.

http://www.coinchoose.com/

I am only going to mine litecoin from now on, it is the only one I see as a contender... Yeah I know BBQ can show as profitable for a couple hours but as soon as difficulty goes up then you are back below the profitability line and so it is pointless. And if the guys at BBQ.org continue on track then they are doomed to fail. They dont even come say hi when you introduce yourself lol... I tried to gain interest and increase the traffic and conversation but to no avail... There is hardly anyone that goes to the site. Yet admin claim to recieve 50 emails a day! Lmao... Be nice if they could tell those people to post on the bloomin forum. Though I suspect it is lies.

I think all these alt coins are there to distract miners from real cryptocoins. Nothing more.

IMO There are probably too many alt coins at the moment.  But I do think they serve a purpose.  We need something other than LTC & BTC on the market.  I think there is room for the alt coins, especially since the cryptcoin scene is still very small and has a lot of room to grow.  Which ones will end up on top remains to be seen however.

Impending Upgrades !!!

Update - The WDC pool I am testing the upgrades on is nearing the end of it's BETA phase. 

This means upgrades are coming to BBQ soon! 

Stratum support is active on port 3333. And you're right, since stratum was added my stales are around .2%

Wrong thread, my bad.

The upgraded front end is ready!!!  I'm switching everybody over here shortly.

Once it switches you will have to log in again, but your login & password will not change.

None of your data will change.

The switch over is complete!

I've also increased the share difficulty by one step from 16 to 31.

This will free up server resources so we can open more server slots.

If you have any issues with the new interface, please let me know.

Pool upgrade complete!

Additional Server Slots are available now.

Come and register before they fill up!

http://silverwolf.ath.cx/bbq (http://silverwolf.ath.cx/bbq)

Why has the difficulty been removed from the Block Stats page? I found this very useful. Can you please put that back?

Thanks.

The new site has a proper Zero Variance line in the graph, this is what the old (Difficulty * 10000) graph was hinting at.

It goes up and down with the difficulty and shows how many shares it should take to solve blocks based solely on the difficulty.

It serves the same purpose as the old graph, but presents it in a better way.

In this way you can evaluate the server's "Luck" by comparing the actual shares to the zero variance shares.

I may be able to add a third line just for the difficulty though, if anyone liked the old style graph better.

I will look into it, but the next thing I have to work on is fixing the vulnerability in the manual withdrawal logic so that I can re-enable manual withdrawals on all of my pools.

Everyone has to use the Automatic Withdrawal Threshold to withdraw at the moment.

I've been working on that since the SBC pool was attacked yesterday, but I went ahead and pushed out the upgrades to the BBQ pool because they were ready and it will significantly cut down on server load.

Yes I fully understand what the new graph means, I just prefer having the difficulty graph there to know what it was throughout the day without doing some math calculation (which I would have to spend time to dig up in the first place). That difficulty graph was one of the reasons I chose this pool over the others, and I definitely prefer it better. ;)

The NSA is watching your graphs

Pretty sure I can add it back.  I'll put it on the list and work on it when I have a chance.

They must be really bored... :)

Also if the share difficulty just increased its probably time for me to stop mining. Im barely mining anything with my old computers as it is. But I will be back when my new box is finished being built

I only increased it slightly, 31 is still very low.  Give it a try and see how it works for you first :)  You should get roughly half as many shares as with the old 16 setting, but each one will count for twice as much as before.

I've been thinking about a way to have a port for slower miners with a lower difficulty and a separate port for faster ones with a higher one.  When I work out all the details I will work on making it available.

Vardiff would be better but that's....well...complicated to implement with this environment.

That would be much appreciated, thanks silverwolf. Keep up the excellent work, I can tell you really put a lot of effort into these pools of yours.

I did notice that I am getting about half as many shares as before. However, I dont think they are quite as near twice the value. But that is ok. My computers suck, I havent even tweaked them yet, and I dont think you should have to specially create or make any concessions for people like me that have really slow equipment. Its a nice thought but you may just be too generous

I think slower miners should want to get or create a better rig and not be catered to. If they are, they are going to expect that with all pools and it removes the incentive to either get new equipment or even tweak (or learn to tweak) what they currently have access to.

Believe me, I would benefit immensely if you made any concessions for slower miners but I dont believe you should just based on the principle of the matter :)

First I tried adding the difficulty back onto the graph as a third item.  It worked, but looked stupid because it exactly mirrored the movement of the zero variance line. (and I mean exactly.  It's the same line.)

So, I took it back out of the graph and added a Difficulty column to the "Last 50 Blocks Found" Table under the graph.

This looks fine and it's information people may find handy so I've updated all my other pools with it.

Hopefully this, along with the zero variance line will give you what you need.

Sure they are, since the share difficulty doubled everyone on the pool is getting about half the number of shares as before.

Strictly speaking I guess each share has no value.  It's not like PPS where you get paid by the share.  Instead you get a % of the block value by counting how many of the lastNshares were from you.

So, you see it doesn't matter what the share difficulty is really.  The lastNshares value doubles when the share difficulty doubles.

Sort of like this:


Either way you get the same percentage.

There is more to it than that of course, but it gives you some idea of how it works.



Well, if I did implement a lower difficulty share port for slower miners, you wouldn't earn any more coins.  As I would have to change the way the scoring works.  I would set the slow port to a fraction of the difficulty of the fast port and shares submitted to the slow port would only count for that fraction of the big ones.

For example if the fast port is Diff 60 and the slow port is Diff 15 than it would take 4 shares submitted to the slower port to equal 1 share submitted to the faster one.

That's the only way to do it right.  It would only make a difference if the miner in question was too slow (or nearly too slow) to get shares at all, other than that payouts would be the same.  

As long as you are getting shares fairly regularly it wouldn't make much difference, the variance might be slightly lower.

The only reason to do something like that would be to allow for even higher difficulty shares on the faster port (Doubling the share difficulty almost cuts the server load in half, because it's now processing half as many shares as before) while still allowing for slower miners to use the pool and get something.  I would imagine that most miners would be on the fast port.

I may or may not implement something like it, I would rather have a full-on Vardiff implementation but the stratum server I am using doesn't support it.


If the share difficulty were to be set so high that you couldn't get any shares at all, or got shares very sporadically it would be a great help, other than that it just wouldn't do much.

Most of our new users are not donating anything, so I've set a 1% pool fee to help cover the costs of the server.

This will allow me to keep the pool running and to continue improving it.

Thank You.

I had to switch to another pool because I was earning more with their share difficulty.  Now that yours is the same (31), I'm back here.  It's weird how much your earnings are affected when share difficulty isn't set to something that's optimal for your hardware.

+1  :(

hmm, under optimum conditions the small change I made shouldn't make much, if any, difference at all in your payout.

I suppose if the stale rate is high or if your pretty far away from the server (network lag) than it might increase it.

Manual withdrawal functionality has been reworked to prevent exploitation and has been enabled again.

How it works now :

When you click the "Cash Out" button, instead of sending the money immediately it "Schedules" the withdrawal request.

Withdrawal requests are processed every minute when the cronjob runs.

Enjoy

All operating pools exiting BETA status as the code is working well and quite stable.

just joined with a HD7950 Flex OC 3gb working @450kHash/s ... Can't manage to make it faster without crashing - CGminer 3.1.1
Looks like bitcoin mining is over, dead. with ASICs coming revenues droped (divided by 6 in a 2 months).

very low difficulty, few people => high revenues.
For the moment, far better than litecoins too.

Thank you !

Glad to have you with us!

We still have plenty of slots open on the server, come and get some BBQ would ya ?

Here's a guide for overclocking the 7950 & 7970 written I believe by the developer of cgminer (I copied and pasted it when I found it at some point).  It is fairly in-depth and is a slow process, but will yield the very best results possible with your hardware.

I have good news.  I'm putting the finishing bits on a VARDIFF implementation for the BBQ Pool!

A Custom VARDIFF implementation matches your miners with the perfect ShareDifficulty for their hash rate.

It should be online in a week or two.

SWEET BBQ !!! Thanks.

I apologize for my recent lack of response on the forums and the support tickets.  I've been in and out of the hospital this week.

I'll do my best to get caught up this weekend.

Thanks for your patience.

Opened up additional server slots!

Get your account before they fill up !!!!

WE HAVE RESOLVED THE ISSUES WITH THE PAYMENTS ON THE BBQ_POOL.



ALL MISSED PAYMENTS HAVE BEEN ISSUED

Having some issues with the server due to a move.  The pool will be back up and running in a day or two once everything is moved over.

Sorry for the inconvienance.
