[1500 TH] p2pool: Decentralized, DoS-resistant, Hop-Proof pool

[forrestv]

I keep getting the following error. It's on Arch Linux. Dependencies should be installed and everything seems to work well. It loads shares and build up connections, but after a few seconds this is what I get. Version 5250df6.

neptop, that's kind of normal if you're downloading the sharechain on a slow computer. The "Watchdog" errors just mean that P2Pool didn't respond for a while, in this case because it was spending time processing shares. This shouldn't happen in normal operation.

Another question... can somebody comment why it is such big variance in mining speed?

Is it because of intensity in miner is not on maximum?

Can somebody explain why it is better to set intensity 20% below maximum? ( like -I 8 is better than -I 10 in cgminer)

Seeing some variance is normal. P2Pool estimates your speed from the number of pseudoshares your miner submits, which varies randomly.

Lower intensities make your miner work on smaller chunks of work at a time, so they can start on a new one faster when a long poll comes in. However, I don't think that that is your problem because of the bulges in the dead rate... Maybe look in P2Pool's log around those times?

As I understand it, higher intensity just mean "hey, GPU, run for a longer period of time before asking for new work".  The idea is to minimize time wasted by constantly asking for more work.  But with p2pool, running for a long time without asking for new work means a higher probability that the GPU will spend time working on stale work.

Code:

Failure: twisted.internet.defer.TimeoutError: Getting http://127.0.0.1:8332/ took longer than 5 seconds.

Impossible - because they on the same server + I don't see any errors in log anyway.

Does bitcoin or p2pool use IPV6? I see this strange pattern in monitoring

Definitely possible - bitcoind sometimes gets stuck for a little while and doesn't answer RPC queries.

Is any other log rather that one that I at the output on the screen?

Can somebody give me bitcoin RPC gateway with no lags? I will pay

There's a log file in data/bitcoin/log. Also, P2Pool doesn't use IPv6; The traffic displayed on that graph is tiny anyway.

I've been working on a self-contained network-provisioned bitcoind + namecoind + p2pool USB stick.  I had horrible problems with bitcoind getting stuck for minutes at a time.

I came up with a solution, but it isn't pretty.  I run bitcoind entirely out of RAM now.

I don't think that that will work. It doesn't seem to support the "getmemorypool" RPC call.

I have precisely this setup working here...
BTW, I also have Devcoin and Litecoin working... My USB stick have 8G...
My machine have 1G of RAM...

No block found for like 4h, something seriously stinks here.

Quick, everyone go back on deepbit!

We found 7 blocks in 6.5 hours.
Yeah something stinks here: your concepts of "luck" and "variance".

Wonder what that will do to the lifespan of your flash drive.

Might be faster to install a small HD for the blockchains but still run the OS from the flash drive. Of course if you are doing that, might as well just run the whole OS from the HD...

I'd bet 100 BTC, if I was a betting man, that he was being sarcastic.

I saw his smiley too. Didn't you didn't see mine? heh

No, you are doing something else.  The bitcoin blk00001.dat file itself is over a gigabyte now, and the index is a couple hundred megs more.

[wachtwoord]

It's 952 MB < 1GB, and the index is 352 MB

Hi!

 I just "git pull" p2pool and I'm seeing:

Code:

2012-02-12 17:15:34.299531 > Error while calling merged getauxblock:
2012-02-12 17:15:34.299732 > Traceback (most recent call last):
2012-02-12 17:15:34.299992 > Failure: twisted.internet.defer.TimeoutError: Getting http://127.0.0.1:7333/ took longer than 5 seconds.

But my namecoind is running normally...

Any thoughts?!

What setting do you guys use for "powertune" in cgminer?
