Heh - I was arguing that it should just work then got corrected (pointed out I was wrong) and worked out why back here:
https://bitcointalk.org/index.php?topic=18313.msg1311688#msg1311688

You now seem to be saying it will 'just' work Tongue

Implementing Stratum in P2Pool without adding the extra p2pool coinbase rules to the miner will be no different to using GetWork as far as I see.
Since without those rules, the only thing the miner can do is roll the nonce and the time.
So in reality it will just be 'getwork' not 'stratum' going to the miner.

You will still only be using roll-n-time in the miner until the miner knows the P2Pool rules to add to Stratum - since stratum updates the secondary nonce in the coinbase but of course doesn't update anything else in there, since for non-share chain, nothing else is required - but for p2pool you do have to change something for the share-chain (I've no idea exactly where it is in there)

It didn't just work - It required a change to P2Pool's rules to allow a 4-byte nonce in the last txout script. I mentioned the possibility here:

However, I discovered yesterday that Stratum is flexible enough to roll any data in the coinbase transaction at all, though, so rolling something in the last txout script is probably possible (though it would require a change to P2Pool's rules).
So a hard p2pool fork?

Sorry I guess I'm just too used to BTC devs running screaming every time a hard fork is mentioned ... so I didn't think that's what you were referring to.

Sorry I guess I'm just too used to BTC devs running screaming every time a hard fork is mentioned ... so I didn't think that's what you were referring to.

Most of the p2pool upgrades that I've seen are hard forks:

Quote
P2Pool release 9.0 tag: 9.0 hash: 2cb4d8381e179f71ea2075cdce948ea83cf0dc55

HARDFORK: Upgrade is required! Hardfork will happen after 95% of the pool's hash rate has upgraded. Everybody having not upgraded will be split off into a tiny P2Pool.

MMinerMonitor author, monitor/auto/schedule reboots/alerts/remote/MobileMiner for Ants and Spondoolies! Latest (5.2). MPoolMonitor author, monitor stats/workers for most pools, global BTC stats (current/nxt diff/USD val/hashrate/calc)! Latest (v4.2)

It's less severe than a bitcoin hard fork because worst case, you are just left solo mining.  It's not like you are on a different bitcoin blockchain and can't spend your money anymore.

Except that all your unpaid shares are worth nothing once the fork disappears.

How fast should a miner ask for updates from P2 pool?    I can do 1ms to 10,000 ms.

ALSO, if you want to parse the text window output for keywords to cause actions, you can use a program called : SCANCODE

got 5,07 bitcoin in 12 hours of mining Cheesy  Roll Eyes (~4,5ghs, estimated by p2pool 0,62-0,80/24hr)




Mystery solved:  That's not 5 BTC in 12 hours.  It's 5 BTC in 26 hours Smiley

dont count the one from the 10:11 i am counting from 18:00 > ~6:00 wich is around 12hours Wink

yeah you would need to hide the whole address and probably payments too because as I said you can look at the output of the blocks and figure out who someone is from payment amounts alone, or even a couple of letters of the address.

That's expected - Just don't go to that page like that. The URL should always have a share hash on the end, like http://vps.forre.st:9332/static/share.html#00000000004506b7e27ad78c40fedc063bbe417936b99316856c0e7338ac5250 The error happening isn't harmful.

Your miner should support long polling so that it doesn't have to do timed polling. Failing that, 100ms or lower, depending on how much overhead you can cope with.

I have the only cuda miner in existance. (rpcminer)
It seems that because the cuda cards aren't as efficient at hashing, the community has altogether abandoned cuda and any new miner support for nvidia and cuda cards.

Even if someone dares mention the evil "nvidia" they will get 5 hashes at the mast.  
The RPC miner defaults to 4000ms polling.

So this means that there are a ton of nvidia users out there with outdated miners (because they have been abandoned)
Unless they all use the switch -workrefreshms=100 their polling rates will stay at 4000ms.

Don't tell me to get ati cards, if I had that kind of money, id just design my own fpga/asic pcb and be done with it.
I use what I have.   Now if someone is willing to throw me bitcoins so I can buy two of the latest ati cards..go ahead, my address is in my sig.   Smiley
But then id need to purchase a gpu mod for my swifttech gpu cooler blocks.   And I'd have to re-run all my PEX coolant lines...etc...

I'd rather just use all the money and extra effort, by doing a fpga/asic design. (i used to do dsp/fpga design for milling machine controllers and drives)
 Why buy new vid cards if they are going to be as useless as nvidia in about a month or so.

Meanwhile regarding your rant full of inaccurate information ... if you spent the money of your electricity bill, that you using mining on the nVidia card, to buy BTC, you'd get more BTC and also help increase the price of BTC ... and reduce Carbon output at the same time
But if I didn't mess around with these miners, and learn all about this stuff, and just purchased the BTC,
 i would be like ever other noob who hasn't a clue of how and why bitcoin is a better option than our current Federal Reserve System.
(corrupt officials can't exactly counterfeit BTC)

Like I said I am not here to mine, just to learn about the whole process, and what exactly is being "mined"

I disagree that my COMMENT was complete inaccurate, but my time and electrons are worth more than to argue with you over something that I already know.
There are no good cuda miners for windows, and the rpcminer was last updated nov of 2011.

And I am not going to switch to linux just to try a different miner (you show cg miner)  
I tried cgminer with opencl and my hash rates were 1/2 of the cuda miner, and it used 75% cpu while using 100% of both gtx460 cards.
Rpcminer uses almost no cpu while using 100% of both gtx460cards.

The coin labs miner looks like its a mod of rpcminer. Plus is looks like you must use coinlabs to use their miner.
Why would you tell me to use a miner that requires me to use a different pool...  
I am posting in the P2Pool because that is what I want to use, im not going to switch to a different pool just so I can use a special miner.
If the miner won't even work with the thread topic(P2 Pool), don't mention it, its useless info.
https://bitcointalk.org/index.php?topic=99523.0

My point that I was trying to make is ati owners can choose between like 10 different miners, but nvidia get what...   2?
(if you call cgminer even viable, at the horrid performace it does)

Tell ya what lets agree to disagree, because you attack my post and say its full of crap basically, but then you mention that I must switch to linux... to use cgminer...  cgminer sucks with nvidia..   or use coinlabs miner, which IS rpcminer/requires you to leave p2pool...  

But hey, everyone ignore me cause all this is completely inaccurate.


So lets make some use out of this post...

If i set my refresh rate to 100ms, at my low has rate (150mh/s) won't I never find a share because my GPU's don't have enough time on the current block to find any shares?
Doesn't the refresh rate REQUIRE a minimum hash rate to find any share or block?
What would increasing my refresh rate to say 1000ms do?
Give me potential dead/orphan shares? (local dead on arrival)

I have tried refreshrates of 100ms, 750ms, 4000ms, 8000ms...
If I go longer refresh rates (above 1000ms) then I will get lots of dead on arrival, but I find that my share # goes up.
 Some arrive as dead, orphans, but more show up as good shares.
If I set my refresh rate to say 100ms... I find that I produce NO shares, no dead, and no orphans, in a 24hour period.
If I set it to 750ms, I find I can produce 1 share every 4-8 hours or so.
If I increase it to around 4000ms I have lots of local dead on arrival, with even more shares than a lower refresh rate.  (but more dead and orphan shares show up.

I guess I don't fully get it all, but my understanding is that if you set the refresh to a longer rate, you might produce old shares.
But having some dead/orphan shares is better than none at all.    So it seems that people with lower hash rates should use longer polling?
They may get more dead, but at least they will get something.  
 I found that not all were dead, only say 10% were dead when I had a polling rate of 4000ms.
So what gives, does polling rate depend on your overall hash rate?

What I notice, is with very low polling rates(100ms or less), I produce no shares at all.   Even if I run it for two days.
But if I set it to 750ms or longer, I will produce about 1 share every 4-8 hours.
And if I set it to about 5000ms, I will produce about 1 share every 2-4 hours(with 25% of those shares ending up as dead/orphans)

So does polling rate depend on hash rate, if you want to produce any shares at all...(dead/orphan/good)

Well I guess CoinLabs must be hiding the CUDA miner that ckolivas wrote for them months ago ... ?
(I don't know I don't have anything to do with CoinLabs, I just know that ckolivas wrote a proprietary CUDA miner for them some months ago)

...

... and your previous post started with

I have the only cuda miner in existance. (rpcminer)

then

So this means that there are a ton of nvidia users out there with outdated miners (because they have been abandoned)

... anyway ... cgminer compiles on all sorts of platforms - even windows Tongue

Ya know what.. dude...  since you seem to imply that there are tons of options for cuda miners....

Link me to some windows CUDA miners that don't require me to switch to linux or switch pools.

Otherwise, kindly f-off.

Oh, and since were on the topic of cgminer.....   BEGIN RANT.

Someone f-ed up big time when programming/designing the cgminer to bitforce interface.


Its funny, because I happen to find a program that was transmitting on all FTDI serial ports every 10 seconds at 115200 baud.

It turns out that one of the "miners" called cgminer has code in it that wrecklessly opens ALL FTDI ports and transmits on them.
Its a program that is trying to find a device called "bitforce". (its a fpga hashing cpu) to mine digital hashes.
The problem is, that it opens ports to other devices that use the FTDI chip ALSO, and transmits ZXG every 10 seconds on ALL FTDI ports at 115200 baud.
From a bitforce perspective, they don't give a shit, they just want their product to work.
From a 3rd party hardware engineer, that is really really mean to do to other hardware developers that develop using the FTDI CHIP.
 (tons of microcontroller programmers and devices use it)

I know no one will change the code to be more "serial port" and other device friendly, and I also know you won't mention it to the developer.
But it really IS bad practice to open ALL ports every 10 seconds, not just open them, but actaully transmitt, and operate the DTR lines(many devices use the DTR to operate the reset line on the microcontroller/chip.

https://github.com/ckolivas/cgminer/...ver-bitforce.c
This code is included in almost all "miners" and so most computers that run a miner program most likely have this FTDI port access every 10 seconds
It will transmit "ZGX" at 115200 baud every 10 seconds on all FTDI ports.

Why a simple switch couldn't have been implemented to turn the bitforce port attacking ON, instead of having it run 24/7, till it finds a bitforce device, beats me.

Most of you have no idea that your cgminers are doing this to every serial port on your computer, every 10 seconds, because most of you don't do hardware development.
But if a hardware developer were to see this activity from a program, that hardware developer would have a few CHOICE words to use, and they wouldn't be pretty.

Quote me where I said that?

Then re-read my last post.
