Has anyone Used Reaper and p2pool LTC yet?

I am using reaper to mine LTC to my p2pool instance for the past couple weeks.  It is working great.

Me too...

Lol past performance is no indication of future success. I was simply happy to have made some coins this week  Grin. Sorry  Cry .... note to self ...... skip sharing happiness with others .....

On a different note, the stats webpage will not load for me today from any comp I have. Does anyone know what's up?

Not loading for me either.  Something must be wrong with it.

I'm glad to see some good returns finally on p2pool.  Makes up for those block-every-24-hours days. Sad

Temporary fix is in place.  A better fix in the works that should also improve performance.

I was wondering how this page calculates the performance of finding blocks (7 days, 30 days, 90 days).  Is it based upon when the block is found, or the average for the block?

For example, let's say the hash rate for the pool was 300g/h.  It was a long block, and a bunch of people gave up before it was found.  When it was found, we were at 250g/h.  If the performance is based upon when it was found, it would look like we did better than reality, because it would take longer at 250 than it would at 300, when in reality, we were at 300 for most of the time of the block.

Conversely, if were at 250g/h and then suddenly jumped to 300 and found a block, it would look like we did worse than reality, because it would be shorter at 300 than it was at 250.

Since the hash rates seems to swing wildly from 200 to 300, I thought I'd ask.  If it's based on the time the block was found, it needs to be taken with a grain of salt.

Right?

Pool hashrate is sampled every 5 minutes, and the luck estimate/calculation uses the average of those samples over the duration of the round.

The fact that pool hashrate is sampled every 5 minutes is actually the reason the page loads so slowly (there are a zillion 5 minute data points between now and last february when I started collecting 5 minute samples).  The 5 minute sample are useful for the luck calculation, but the graph doesn't really need to be that precise so I will be changing JSON API to return fewer data points to the graph which will cut down the time for the page to load (block luck calculations happen on the server and will still use the 5 minute samples).

Great day yesterday.  I have been mining for a month now, and P2Pool seems to beat other pools. Cudos!

I have been running just shy of 2Gh for over a week- non-stop. "current payout" listed at around .15at first, then .41 (after 4 days), now .28 to .33.

I have been trying to figure out how the payout amount is calculated and such.  All in all, it seems fair according to pool speed.

Question:

Over 8 hours while I slept, I gained 22 shares in 8 hours.. I had 418 when I woke up 5 hours ago - now I have 419 (in 5 hours time).
Orphans and 'Dead' have not changed  and 'expected time to share:' continues to be between 18 and 22 minutes.

Any ideas?

Just crap luck, I'd guess.  I run between 4-6GH/s on p2pool and there have been times where I've gone over an hr between shares.   

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).

Look at week stats. One day is not enough to make any close estimations.
On my crappy 150MH there was days i not get even one share, then 3 in hour. Just luck Smiley

Yes but hash rate is an estimate ...
Really it should keep the history of shares and use that - which is accurate.
Shares is the only accurate measurement of a pool.

I agree completely that in a perfect world that would be better.  I just don't care about the difference enough to invest my free time to make the substantial changes required to make that work.  If someone else wants to do it and provide me a JSON feed of p2pool blocks along with the actual number of diff 1 shares that went into that block, I'm happy to replace the current hashrate based estimates.

p2pool is better than Deepbit over last 90 days (assuming deepbit had 100% luck) according to p2pool.info!

90 Luck has climbed above above 97% so if you add in the 0.2% of transaction fees you get from p2pool and subtract the 3% fee deepbit would have charged you, you would have been better off on p2pool over the last 3 months.

-- Smoov


BFL FPGA singles search all 4b nounces before returning control to the miner with a list of 1 difficulty shares it has found. This takes about 5 seconds. In this 5 seconds when mining on a "normal" pool the chance of a block being created is very small so you get very few stales.

On p2pool there is a new share every 10 seconds. So with BFL FPGA single you get about 50% stales. BFL need to fix this issue.

From what I can gather the bfl's can only be given new work every 10 secs which for p2pool means they produce 50% stales.
