Thing is, besides the recent single block, it seems to be working fine for everyone else ... and that's a lot!

(...) Everything the same, a 6-hour round should absolutely pay better than a 1-hour. More work, more uptime, higher cost of running.

Why should it pay more? Whether it takes 24sec or 11hrs to find a block - at the end of the round it always brings exactly the same amount - 25BTC (currently).

Aside from that - I agree about the second part - shorter rounds are more profitable. But that's luck. Wink

On the good side - this is going to be a pretty large block, so that gave me enough time for my score to restore to normal (in about an hour).

That's the thing, Slush's hop-resistant algorithm only really works well on short rounds. On occasion when we've had <5 minute rounds I can make a killing but there is nearly no difference in reward between a 2-hour round and a (soon-to-be) 6-hour round. Is that a small/medium miner thing, or can bigger miners corroborate? I get about 1.8 Gh/s between me and my buddy. On a PPS pool you get what you work for but here, because the score metric resets every so often, everyone is pretty much capped for any given round. At this 10.1M difficulty the highest reward on a single round I've gotten was .00576. Everything the same, a 6-hour round should absolutely pay better than a 1-hour. More work, more uptime, higher cost of running.

You need to know how block mining works.

It doesn't matter how long it took to find a block, a block will always contain ~25BTC. It's all about luck. Slush's score system even things out over time.

If it's proportionate returns you are looking for, you're at the wrong pool. The PPS system will suit you more.

I already am mining on Slush's Pool 14 hours. Power 2200Mh\s. Why I do not calculate Namecoin?


Hi, under system statistics on Slush pool you have Bitcoin blocks and Namecoin blocks..you can look there for NMC,

give me a link - I do not see

It is no different for the pool - "you hit a getwork that returns 5 shares in the same 5sec - it looks like you have 5 times faster miner"


And when that happens for thousands of miners? They certainly don't get the same "luck".

Pool is 10Thps. Assume pool D = 1. That's 2328.306 D1 shares per second. Hashrate is averaged over 30 minutes, so that's ~ 2328.306 * 30 * 60 = 4190951 shares.

Use this page to calculate a 95% confidence interval, which results in  4186940.51 to 4194965.33 shares per half hour. That's about  +/- 0.1% variablilty with 95% confidence.

Let assume average pool D = 100 (ridiculously high, consider this an upper bound), so 2.328306 shares per second, and ~ 4190 shares per half hour. This bumps the variability up to +/- 3%.

To get anywhere near your 10Thps +/- 10% figure, the average pool D has to be about 1000. This has to be even higher as the hashrate increases.

tl;dr pool hashrate variability is not significantly affected by the luck of the individual miners.

I do not agree, but i do not want to argue, so i will just point that for normal distribution ( https://en.wikipedia.org/wiki/Normal_distribution ) after normalization, it doesn't matter if the difficulty is 1 or 10M - you have the same variance in % as you have the same standard deviation, only a different mean value

API2 forwards me to stratum how do I force getwork with guiminer?  Having issues at work think they updated the firewall stratum doesn't seem to work for ANY pool need to move everything to the backup line but don't want to wait 3 days until I go back out.

The expected number of shares in a given time period is not normally distributed,it's Poisson distributed, so normalisation matters - not that it's advisable to do this with a discrete probability distribution. Did you attempt to calculate results for yourself? I provided you with the link for that purpose.

You could try this too: http://organofcorti.blogspot.com/2012/10/71-variable-pool-difficulty.html

It's about pool difficulty, but you can see how it applies to this discussion.

tl;dr: The higher your hashrate : difficulty ratio, the lower your variance.

Edit: When you write "i do not want to argue" I read that as "I don't want to find out if I'm wrong or right". Come on - man up! Smiley

If you can convince me I'm wrong I'll happily admit it. That's how science works.

I do not want to clutter this thread and do not have much time for arguing. We are both pretty convinced in our statements, so it will not be quick and easy to make a switch in our opinions.
If you insist, please open a new thread for this and give me the link - i will post some personal observations to backup my point, but still afraid we will endup in agreeing to disagree.

You haven't addressed any of my points and haven't a proof or hypothesis of your own, so no, I'm not going to start a thread.

We'll just have to agree that you're wrong and leave it at that Smiley

@organofcorti  Although I haven't read nearly all of your blog posts, nor understood all of the ones I have read, it is obvious that you have spent a good deal of time analyzing pool mining.  I have also seen your posts in other pool threads and seen your analysis of bitminter.  So I am curious, with all of your analysis, where do you mine?  You may have said it before but if you did I missed it.

Well that would be my fault. If there's something I haven't explained well, please post a comment on the blog and I'll do my best to fix the post or add to it or post a primer on it.

it is obvious that you have spent a good deal of time analyzing pool mining.  I have also seen your posts in other pool threads and seen your analysis of bitminter.  So I am curious, with all of your analysis, where do you mine?  You may have said it before but if you did I missed it.

I don't mine at the moment, and haven't for more than a year (since my gf complained about the noise of the computational hairdryer in the spare room and gave me an ultimatum). I'm waiting on a batch 2 Avalon at the moment, and when I get it I'll be spreading the love, as suggested by Meni Rosenfeld in this post: https://bitcointalk.org/index.php?topic=78031.0 I think cgminer makes that fairly easy.

As to which pools I'll be using, I'm not sure yet. Probably (alphabetic order) BitMinter, Bitparking, BTCGuild, HHTT, Ozcoin,  and Triplemining. Anything using DGM (with setting I like) or PPLNS (with an N that I like). Not Slush's pool, because although I really like the pool and have a lot of respect for Slush and I'm not concerned about losing much due to pool hopping but because I don't want to support a reward method that can be gamed. If that gets changed I'll be adding Slush's pool to the rotation.

I'm not in the stratum namecoins credited.
1) get a namecoin wallet - watch the video and read at the bottom www.youtube.com/watch?v=ezo1t90QLFQ
2) set it up and put the wallet info in to your account to start doing/getting credit https://mining.bitcoin.cz/accounts/profile/
3) keep hashing
4) Profit!

last block i got namecoin credit for was this one

I have put up a dedicated mining computer now, and I'm having a lot of problems with it, but I'll take one at a time. I am running GUIMiner
I'm getting this error message:

2013-05-11 16:26:06: Listener for "OpenCL Slush's": stratum.bitcoin.cz:3333 11/05/2013 16:26:06, Verification failed, check hardware! (0:0:Juniper, 2b5342eb)

when I am running an OpenCL miner connected to your pool.

You have said to others having this problem that it is most likely hardware or driver error, but I can run Phoenix (with BitcoinPool.com) without problems. What could it be? I have tried different flags.

PS: I tried running an OpenCL miner on BitcoinPool.com and I get the same problem:

2013-05-11 16:38:50: Listener for "OCL BCPool": bitcoinpool.com:8334 11/05/2013 16:38:50, Verification failed, check hardware! (0:0:Juniper, 74f69135)

I could try the other graphics card (that has other drivers), but please don't ask me to do it today... I have spent at least 6 hours and 20 reboots on trying to get the graphics cards working as I want, but they still don't. Nothing seems to work the way I want it to today.

My name is confusing, I began mining using an old GeForce card. Now I have ATI cards.

with my initial setup i set GIUMiner ( the default tab ) to Slush's for pool and entered in my user name, with the Stratum changes you have 2 options, set up the mining proxy client or set to ' other ' for the server and port 3333

you could try stratum3.bitcoin.cz or stratum2.bitcoin.cz and do not forget your worker username and password as it ' logs in for work '

I have server set to ' other ', stratum.bitcoin.cz and port 3333, and now I also tried the other two addresses. No difference.
I think the problem is in this end. I'll try to reinstall GUIMiner, but I don't think that it will help. I don't think it is the graphics card or the driver, because Phoenix works. I was running XP on my other computer, this one is 7. Doesn't poclbm-mod (I think it is mod, that comes with the latest GUIMiner) work in Windows 7?

Only time I ever saw that error was when I installed an updated graphics driver.  I ended up rolling back to the previous driver and it went away.  I believe what it is saying is that the share you submitted is not a valid hash which would indeed suggest that the hardware is making a computational error.  But more than likely (and your testing seems to bear it out) the hardware is fine and it is the way the miner is interfacing with the hardware, in other words the driver.

So what hardware and what driver are you using?  Your forum name is for nVidia hardware which you would normally want to use a CUDA miner with, but you are talking about an OpenCL miner which would normally be used for an AMD/ATI card.
