Decentralize your hashing - p2pool - Norgz Pool
hmm my node hasn't picked up a share in over 5 hours. hashing at 700gh/s+ and usually a share comes up every couple of hours. anyone else seeing this?
That's just variance for you... my SP10 has gone for over 6 hours without finding a share.  I've had my S1s go for 22 hours and more without finding shares.  It happens.
cool cheers, yeah I figured that was the case but it seems out of the ordinary with nearly 1th/s to have so much time between shares. All good, still learning the nuances of variation and p2pool.

I did - but not as pissed as most of the p2pool users are with him. This is his chance to actually participate - let's see  Wink

But he has no reason to participate

So then I guess you're assuming that if he actually was active on the project, then it wouldn't affect donations?

in any case, I had my donations set to 0% but I'm fairly certain I sent at least 1% directly to that p2pool donation address, from people with invalid names submitting shares

on the next update, maybe he should make it possible to not input a default address, so then ppl with messed up names end up donating their bitcoins, and you can still have it set to 0% for everyone else

I am currently in email conversation with Bitmain regarding the issues with the S2 (& soon to be released S3) & p2pool firmware/driver incompatibility issues. Bitmain have requested more info from me regarding the issues, however the type of info they require is a few levels above my paygrade/capability - so can someone either post here or PM me the exact problem & I will relay it to Bitmain.

This is an opportunity for the p2pool community to help increase the hardware availability for p2pool, something that so far has been severely lacking for the last year, and is especially important for the upcoming S3's - let's not miss out on this chance.

How can I help? I don't have any S1/S2 hardware to test with (if I did, P2Pool would probably work with it by now...) and haven't really gotten any concrete bug reports. I gather that they have high DoA rates, which I assume is due to high latency responding to pushed new work or high latency sending results.

The main things P2Pool needs in a miner are:
  • Don't have arbitrary limits on the coinbase transaction size or the placement of the Stratum nonce within the coinbase (late generation Avalon miners are guilty of this).
  • Send results/good nonces as soon as possible after they are discovered (ideally within 1 second).
  • Start working on pushed new work as quickly as possible (ideally within 1 second). Also, don't drop good nonces if new work comes in (equivalent to cgminer's --submit-stales option)

If I am correct in assuming that the problem is latency, no simple solution will help existing devices. The parallel sharechains idea (which is my top priority) would alleviate this issue by moving away from the linear sharechain/30 seconds per share paradigm to one where latency matters far less.
Hey forrestv,

I wish I could give you details, but unfortunately I'm half a world away from my S2.  What I can tell you is that when I point my S2 at my p2pool node (or any p2pool node for that matter) it will max out at 850-900GH/s.  I point it to another pool and it hits 1TH/s without issue.

I'd ask that you contact mdude77 and kano.  They have more details regarding what's going on with the S2.

By the way, the S1 works just fine with p2pool.

@forrestv - This is your chance to prove to p2pool users that you actually care - I & every user here would like to see some input from you regarding this - please provide any info you can.....

BIG +1, S2's and upcoming S3's are ciritical to our success.


I'd like to start a bounty for forrestv to complete this.

I will start it with a BTC0.50 bounty offered to forrestv for a working solution for p2pool/anitminer S2 & S3 compatibility with the Ants achieving expected hashrate and shares.

Anyone is welcome to contribute to the donation address, bounty is paid to forrestv (or his designee) upon a working, distributed solution or returned in full in 30 days, I will pay return tx fees for any donation over BTC0.001, if your donation is less, consider it donated.

Bounty Address: 1Ft1DZ4EcpH1jFttDoPwsFbe11a6diyZ1H

https://blockchain.info/address/1Ft1DZ4EcpH1jFttDoPwsFbe11a6diyZ1H

Signed message:

Code:
forrestv p2pool antminer s2 and s3 compatibility fix.

Code:
G7zuvJ7/LPv7LpZveAsQWet1gAR42bnwFRVPB7NsnGqPnWkN8bqSSN1UwR+NnfDs/8LkruqZcVsTTdfcy5pcNj4=

Please contribute.


Edit: Any additional donations (over BTC0.001) will be returned to donation address or paid to Forrest or his designee on or before July 25th, 2014.

My hope is to pay Forrest for work done, lets make the bounty worthwhile.

Donated

this http://www.norgzpool.net.au/antminer.html essentially fixes the issues with the S1 but that's with Kano's fix.

A fork is good too

If forrestv doesn't show up - a fork will be a required necessity........
Forking it will only serve a purpose if you have a set of planned changes. If you have a set of planned changes then you're better off in the long run just pushing code to p2pool itself. Frustration with the current development process does not make the code/changes magically appear.

He does if he wants people to switch on donations again. Anyway, if we can't ensure that future mining hardware is usable with p2pool - it will die - simple as that. The hash rate drop since his spectacular fail of a "statement/moan/bribery attempt" shows which way p2pool is going, it will only get worse as everyone gradually switches off their S1's.......

Copy/Paste of my last received email from Bitmain:

"Hi,
Thanks for the info.
Please kindly provide us compared version of screenshot showing that the different speed when you use the p2pool and other pools. we need to provide more details to engineers to investigate it.
Thanks for your help in advance.

Best Regards

BITMAIN"

As my node is no longer online (stripped down) I am unable to provide these - can anyone chime in with these?

Peace.
Tell them to install one node and test themselves... It isnt too hard i think, for them..

Anyone using mining_proxy with p2pool, doesnt work here - Im doing something wrong maybe. It keeps connecting and closing.

They don't work with p2pool - never have. One of the many........

Oh, thats bad..



It's usually the hardware fault because it doesn't poll quickly

@ windpath: Personally, I think it would be quicker if we done it ourselves. I've spent over a year trying to get forrestv to communicate with p2pool users in this area to no avail. If he chimes in - all well & good - but I'm done waiting & done donating, as are quite a few others. I've had to shut down my node because I no longer have any compatible hardware after over 3 years of mining on p2pool (sold the last of my S1's & chilis). I'm doing this for p2pool - not him.

I feel your frustration, the goal here is to change the compensation method for Forrest if he is amicable.

My node does not donate because I want to attract more miners to p2pool, and I believe Forrest is entitled to compensation for work completed.

This is a bounty for work completed within the next 30 days, if it's not completed any donation over BTC0.001 will be returned to the sender in full.

If it is competed, and the Ant S2 and S3 work as expected with p2pool within 30 days, Forrest (or his designee), will receive the full bounty.

Peace.
Hit up Kano... he's done a crapload of work on cgminer trying to get it to play nice with S2 and p2pool.  Unfortunately I'm in Tokyo again, and don't get back until the end of the week, so I can't send screens of the S2 on p2pool.
