someone should hold leadership with this to say, guys, to put this and this is the best way for now... and even why not to vote for major changes and p2pool bitcoin.conf best template form
you as a provider of quite big part of p2pool hashrate would be that

I disagree. That would be centralizing p2pool. We all have to make our own decisions about how to configure and use this system.

Exactly, plus no two setups will be the same - settings that work fine for one, might not work well for another.

@ forrestv - if you're lurking - how is your testing of jtoomim's performance going?

Haha. I guess a bunch of the people who left will be flooding back. Probably for another dry spell.

Has anyone done any calculation as to how much fickle miners benefit those of us who stick with it?

No calculation, but it seems when we hit a streak of bad luck folks stay for 1 more block, then leave just before it changes back to good luck...

Have the data to compair luck vs. # of miners, will run it sometime...

Right. Won't install that then...I'll stick with my old firmware & ck binary.

This firmware was not developed by Nicehash. It was developed by smit1237. Nicehash is just distributing it.

There are a lot of changes. The cgminer version isn't the default broken Bitmain one, but instead a cgminer 4.8.0 that still submits stale shares. It might have a different default queue and expiry setting too, but I'm not sure about that. In my testing, it gives about 5% higher hashrate than the one S5s ship with on p2pool.

The smit1237 firmware also allows you to upload custom cgminer binaries to /config/, where they will persist across reboots and will be used instead of the cgminer in (IIRC) /usr/local/bin/.

OK, that sounds more like it. I might give it a go on one of my S5's & have a look-see what the queue & other settings are then, thanks for that info jtoomim  Smiley

Edit: Just flashed it & queue is set at 8192  Tongue  Searching for the parameters now to change it............

Edit 1: OK, changed the queue setting to 1 for testing. BEWARE: This firmware does not submit stale shares - I noticed the "no-submit-stale" parameter in the /etc/init.d/cgminer.sh file (line 69), so I deleted it as it is my understanding that the default cgminer setting will submit stales - very important for p2pool......I'll monitor it & report back later.

Bummer. I'm pretty sure that not submitting stale shares is true for the default Bitmain firmware as well, though.

Yes, it is  Sad

After running a couple of hours I noticed the load was much lower with the smit firmware (down from ~2.6 to ~0.7!), making the GUI much more responsive, but the hash rate was very slightly lower. I changed the queue setting of 1 to 0 for a while & my DOA rate has reduced nicely (not that it was high anyway) with hardly any spikes - so I'm going to run it overnight & check it again in the morning. Very happy with the lower load readings though.

Edit: If the results are OK in the morning I'll do a reboot to make sure the settings keep - if they do then it's all good & I'll update my other S5's  Smiley

Be aware that the bitmain fork also intercepts stale work and drops it inside their driver code - before the main cgminer engine gets to see it and decide based on the command line options.

Bloody hell. Why bitmain, why?  Cheesy

Right, so what I need to do is replace the bitmain bork binary with the ck one at  http://ck.kolivas.org/apps/cgminer/antminer/s5/  & drop it in   /config/  in order to make it permanent after reboots - amiright? If so, I might need a little help with the commands on this one...... Tongue  (linux amateur I am)

Hi, May I?

what is
Code:
It is optimized to serve miners with at least 1THs and, most importantly, it has been specifically tweaked to work without dead times on rented hashpower from NiceHash.
exactly.

Hi May I?

what is
Code:
It is optimized to serve miners with at least 1THs and, most importantly, it has been specifically tweaked to work without dead times on rented hashpower from NiceHash.
exactly.

Basically it has a minimum share difficulty target higher than the default one provided by the vardiff algorithm of P2Pool.
This solves the issue often encountered with NiceHash which turns a given hashpower order in dead state if the received (virtual) share difficulty is lower than 128.
This happens also if you set a specific share difficulty when passing the username (btc_addr+diff). It this case mining starts, but then vardiff may turn down the difficulty, for example, at the starting phase or if the hashrate experience a drop. In all these cases the NiceHash order becomes dead and mining stops.
The new minimum value has been chosen to serve miners that are capable of at least 1 THs (the minimum NiceHash order has 5 THs).

EDIT: Now that I'm thinking of... I probably said something not so correct about the minimum needed hashrate to mine on my node since we are speaking of virtual share difficulty not actual.
I need to re-think of it after I get some good sleep (and bed time is still far...), but either way the issue with NiceHash is actually solved and the local DOA is around 3% on average which is near what I was trying to achieve. I'll take a better look at it tomorrow morning, time to do my real work now!

Well, it's been a strange day today. Got neg'd by dogie then verbally attacked & insulted by this Carlton Banks guy while wishing the best to a new p2pool node:

+1 for p2pool, the more the merrier  Wink

Wow, what a lying POS.

To all that it may concern: this is the same sock-puppet master who tried to destroy p2pool by bullying it's developer off the project. Recommendation is not to listen to one single word that comes out of it's slimy mouth.

What on earth are you talking about  Huh

Feel free to come over to the p2pool thread & explain how you came to this conclusion, as I don't want to derail OP's thread.

...does anyone know what he's going on about?  I know he reads this thread, so here's my last conversation with forrestv from a few weeks ago for him to read:



Click image or read it here:

https://github.com/p2pool/p2pool/issues/270

Hardly "bullying the developer"  Roll Eyes......I've done nothing but support & promote p2pool since day one.....I'm confused......what's with the p2pool haters?

Edit: BTW, here's what I got with the new Bitcoin Core client:



....nice  Cool

I believe it will not. In which case, I may tweak this firmware instead Smiley If I do, I'll make 4.9.0 the default.
