I do feel however that any gpu miners days are seriously numbered. And the quickly rising difficulty is going to bury them and necessitate changes to p2pool to accommodate the longer time needed to do much larger difficulty, longer work times. it will pretty much make gpu mining bitcoin unworkable except for the complete die hards, the stupid or botnets within a few months.

Actually... people have been saying that for 6 months now.  ASICs are still very hard to come by (and there's no way I'm spending $10k on an avalon).  At $150/BTC, and electricity at $.05, I'm still very profitable with GPUs.  Not reaping it in hand over fist like the lucky folks who got batch 1/2 avalons, but still very profitable.  Probably more so than it's ever been, even back pre-halving days.  The rising value of BTC is what people seem to forget.  Yes difficulty is 2x what it was a few months ago, but so is the value of BTC.

As for forking.. I'm not using p2pool as long as there's < 1TH in it.  The variance is simply too much for me.  If the ASIC fork is unusable by GPUs, then I simply will never use p2pool again.  It's unfortunate, but that's how it is.

M

Agreed. Also, if I DID have an Avalon I would point it at a more compatible pool that would get the most out of it, obviously. Forking p2pool is not a good idea at all, what would happen if Avalon chips decide to pack in after 6 months? Far better for everyone if p2pool was compatible with ALL miners, as is the norm.

lenny, if you consider 3 blocks/payouts  per week the most you've earned than anywhere else you must have been doing something badly wrong before...... Roll Eyes

sure, it's still more than any pool that charges fees

the amount earned isn't the issue, the variance is

You can be 0% on bitminter.

i was going to mention the added perk of being able to mine the illustrious 'ixcoins' on p2pool, but it looks like Vircurex has stopped trading ixcoins... even as they were at like a 6 month high..   jesus!   Shocked

Dacentec, best deals for US dedicated servers. They regularly restock $20-$25 Opterons with 8-16GB RAM & 2x1-2TB HDD's (ofc, usually lots of other good stuff to choose from).  I did a Serverbear benchmark of one of my $20/mo Opteron (June last year), it's here.  Have had about a half dozen different servers with Dacentec, & none have failed to sustain at least 40MB/s (burst higher). My favorite is a 12-month rent-to-own ZT Systems 2XL5520 16GB 2x2TB SATA for $40/month (got lucky with the 'off-brand', haven't seen a RTO 2xL5520 for under $50/mo since -- at least for monthly contracts).  wholesaleinternet.com has some ancient 2-core intel CPUs @ $10/mo sometimes (I got an Intel Core 2 6300 @ 1.86GHz, with a 250GB HDD with 46000 hours on it, LOL. $20 @ Dacentec is much better, if you can grab one). joesdatacenter.com (same location as Wholesale Internet) also occasionally has specials (or if you don't want to wait, it has an AMD Opteron 170 @ $16/mo).

Anybody else has problems currently?

It appears my current problems may have an answer here:

http://www.terracointalk.org/index.php/topic,3.msg275.html#msg275

Getting too late in the night to set up cgminer though. I'll have to play tomorrow.

Edit: Ah, who needs sleep? cgminer installed and graphs are doing something. Yaysome!

Edit2: OK, now to figure out how to get it running under cygwin. Gives "redirection is not allowed". Not a show-stopper but I like to be able to ssh in.

I also haven't been paid in about 9 hours myself.  LTC blocks seem have been solved during the night but no payouts for me.

17 hours now, at 42kh/s, but zero payout. All older payments have cleared, but nothing new. Waste of CPU and energy, I am out.

I left p2pool running and restarted my litecoind and and cgminer and got paid within an hour.  I think litecoind got messed up somehow.

I'm running a small GPU on p2pool (V 11.2) for mining LTC at around 145 kh/s with cgminer (V 2.11.4).  Everything seems to be working but I noticed that instead of the usual 3 shares/minute on BTC mining, I'm getting about 120 shares/minute with LTC.  Basically the shares are flying past.

Is there a way to increase the share difficulty my miner sees to slow this down?

It's the same. You add /x000 to your username to increase share value. And add +x to increase difficulty value.

so you could use aseras/2000

Or

Aseras+4

Or aseras/2000+8

Many combinations. You try to make it so that you find a few shares per hour.

Hold on, can you please explain? Smiley
username/2000 - that's "big shares" difficulty, which p2pool counts as our income, correct?
username+2000 - what's exactly that, then? Smiley Difficulty given to stratum-cgminer?

username+5 would adds to 'base difficulty' or w/e, so instead of it being 1, 2, (or rarely 3), it'll be 6, 7, 8.  that's what it uses to calculate your hashrate on the graphs  (so essentially, yes, in response to your question)

username/xxxx (assuming it's higher than the p2pool assigned difficulty) is what difficulty shares you're trying to produce

Dacentec, best deals for US dedicated servers. They regularly restock $20-$25 Opterons with 8-16GB RAM & 2x1-2TB HDD's (ofc, usually lots of other good stuff to choose from).  I did a Serverbear benchmark of one of my $20/mo Opteron (June last year), it's here.  Have had about a half dozen different servers with Dacentec, & none have failed to sustain at least 40MB/s (burst higher).

I've tried modifying the difficulty using this "username/xxxx+yyyy" syntax but it doesn't seem to have any effect.

All I wanted to do was reduce my share solution rate by about 1/40 of what it is right now.  I'm looking at the "u: xxx/m" field in cgminer to determine this.  It's currently showing about 120/m.

Too much like hard work. I think I'll just rework my widget I wrote for the HHTT pool. It may need to work a little differently since the pages aren't public (and I wouldn't recommend anyone port forwarding 9332. Though I don't know that would necessarily cause any problems directly).

Ok... change the username being passed to p2pool.

adding "/1000" would change the minimum share difficulty you're trying to find, to diff 1000 shares. This option would be the one to slow down how fast you're finding shares. Since payouts take the target difficulty into account, finding fewer high-diff shares would pay out the same as many low-diff shares.

So, say with LTC right now, you're seeing "Share difficulty: 0.640942", and you add "/2.5" to the end of your username, you should start seeing the 'new work for worker!' lines listing your "Share difficulty: 2.500000"... if the pool diff goes higher than that, then you'll follow the pool diff, so it is whichever is higher.

adding "+0.01" would change the other difficulty. Your new work for worker is showing "Difficulty: 0.000009" for example. This is the level of work your miner is sending back to p2pool for speed calculations. If you add "+0.01" to your username, then p2pool will be asking for 0.01 diff shares back for speed stuff, instead of the dynamic one it sends.

Both of those can be used independently.

Also, there is a cap on the + that p2pool will use. I forget exactly how much, but if you set it too high, p2pool will ask for its own maximum from the miner, based on what the Share diff is at the time you start mining. This isn't much of an issue, you'd still be using a much higher miner diff than before.

Using + is _not_ a mathematical operation like the person a few posts above suggested. "+" is just a flag, same as "/", for p2pool to look for to parse out the number being passed to it, so don't use + or / in your username unless you are intending to use the options.

So...
 "/####" is target share difficulty
"+####" is target miner difficulty

Lemme know how they work out for you now.
