I guess I just don't get it. I come with 4 years of experience on a different forum (overclockers.com) where the people who have the knowledge of something will gladly share what they know when asked. If they see a thread that is a repost, or a comment that has been answered elsewhere, they just point you in the right direction and don't repeatedly ridicule the people who asked.

I just won't post in this thread anymore since I just get shit when I do. Have a good rest of your day, fellas.

No, the problem is that what you are saying is:
"I don't want to have to read the documentation that people here have gone to the trouble of writing, just tell me the answer"

You do realise there is a reason why the acronym RTFM exists right?

You are at the top of the list of reasons.

I know there was a discussion a while back that BFL gear would essentially *never* be compatible with p2pool, is that still the case?

As more and more pools implement fees, p2pool becomes more enticing for all of my rigs, but it seems BFL will never be possible as Butterflylabs won't get their asses in gear.

If I remember correctly, the current Singles will never be compatible. However, the Mini Rigs and future ASICs are/will be.

What I said, is that I wanted help. You interpreted my asking for help as a sign of me being lazy. It's a matter of perception, and nothing more. And I didn't know what the acronym meant before Raven said to me because, like I said, I don't typically deal with people who can't copy and paste a fucking link.

Is it still the case that BFL singles are not p2pool compatible? I have 6 on order and they should arrive in <3 weeks. I really like P2Pool and would like to add the BFL singles to my hashing here.

If they aren't compatible (produce too many stales) what pool would you guys put there hash power in to? I have a BTC guild account setup but was looking at MtRed for lower fees. Any suggestions/discussion would be welcome.

I didn't follow the BFL-p2pool thingie..
Would maybe one of the "public" p2pool "pool" node work?
Those where your diff1 shares are used for calculating payout?

Would there be a loss? If yes, would the miner or the nodeoperator suck it?

From what I understand the incompatibility with BFL singles is how it processes work. Apparently they only process large chunks of data before returning a result to the miner software. This again apparently (because I don't know only parroting what I read) results in ~5 second response time with completed work from a BFL single. That would result in a very high stale rate on P2Pool.

If anyone has 1st hand information please chime in.

For all what I read that disability to drop work and send share when found is real problem in BFL soft.
It just make full nonce and rerutn all shares found. Because it takes some time (about 5sec) most of work is trhashed on p2pool (about 10sec longpool).
Only 2 major changes in current BFL soft/hardware would make it possible to work on p2pool:
- return share when found (not when finish nonce)
- drop/get work on longpool (not when finish nonce lol)

I wonder when was the last time I posted this in here Smiley

Anyway, with BFL, you send work to it and wait ~5s for an answer.
If you abort the work, before the ~5s is up, it doesn't tell you anything it has already done.

Thus there are 2 options:
1) abort work each LP (lose on average 1/2 share per LP)
2) wait for work to finish each LP (lose on average 1 share per LP)

If you abort, you are, of course, aborting a large % of your work since LP is 10s
If you wait, you will end up with invalid shares so that's twice as much wasted work.

So ... nothing you can do about it ... don't mine on p2pool with BFL Singles or MiniRigs
(MiniRigs only lose ~half as much work since they are a bit less than 2 times as fast per card vs a Single)

My understanding is that BFL added the ability to tell a MiniRig to search less than the entire nonce range (and so you can dramatically reduce stales), so it should be possible to use it on p2pool if you have a miner that implements that feature.  The assumption is that the Single SCs will also have that firmware feature when they come out.

So in theory it is just the normal Singles that are unusable.

In theory ...

cgminer also tries to do nonce-range processing on the minirig
I don't know anyone who actually has seen that working on a minirig

However, the code intercepts when that is not working, and switches out of nonce-range processing ... since there have been cases of it not working ... but no idea if anyone does actually have it working in their minirig

I know for a fact early minirigs were send out without nonce-range working, but no idea if they have actually got it working yet.

That's correct, but you need to use this option with cgminer to use it:
--bfl-range         Use nonce range on bitforce devices if supported
It only works on minirigs, and in fact the first few minirigs didn't support it properly.

Also, would changing the difficulty from p2pool help?

There's other public nodes, but they pay you the same as if you were running your own node (based on how many higher difficulty shares you find). I don't think changing the difficulty would do anything to help the BFL issue.
