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

[Rubberduckie]

I'm not going anywhere

Do i need to update to the new version of P2pool: http://u.forre.st/u/bqdrizaq/p2pool_win32_5250df6.zip

Or does it not really matter for LTC?

Don't know if it matters to Litecoin but, I'm using the latest P2Pool version (5250df6 = 0.8.5).

Tomorrow I'll upgrade by Bitcoin connected to my P2Pool to the 0.6.0 rc1...

[Rubberduckie]

I just upgraded both anyway, I'll leave them running overnight and see if there's any issues

thx for your help

Let it rain!   2 blocks in one hour...

Guys, we need to work on the variance

There is nothing you can do about the variance.
It's random (well as random as sha256(sha256()) is)
Increasing the hash rate simply reduces what that variance represents in time since it is directly related to (well actually applied to) the expected block time.

Anyone ever seen a payout from NMC merged mining?

Anyone ever seen a payout from NMC merged mining?

NMC on p2pool is not pooled, so you are merge mining, but soloing too.

I did find one NMC block using p2pool, so it certainly works

[Ed]

thank you for letting know

so it certainly works

does you run python or windows binaries?

python or windows binaries? do you mean *on* windows? Anyway, no, no windows for me, I'm using ubuntu server.

And the fact we've found 7 blocks so far today.

Guys, why "local dead on arrival" spikes so much ( 20% rate)?



I have a feeling that it has something to do with blocks being found.

After I restart p2pool everything goes back to normal 1-2% rate, sometimes even without restart

Mine doesn't spike.  What miner are you using?



(sorry, it's a bit hard to see the red Dead line on top of the dark red device0 area, but it's there and essentially flat)

p2pool - latest from git ( edit : 5250df6)

cgminer 2.2.3
-I 8 -g 1

PS. How can I separate workers on the graph? where to config it. Each of mine miners runs under different username

Guys, why "local dead on arrival" spikes so much ( 20% rate)?

I saw this when I was getting communication errors between p2pool and bitcoind.  Look for connection errors in your p2pool log.

EDIT: Here is the exact error

Code:

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

cgminer 2.2.3

PS. How can I separate workers on the graph? where to config it. Each of mine miners runs under different username

My setup is similar except I experimentally determined that I get the best hashrate (and the lowest stales with -I 6 -g 2).  I doubt that is making that big of a difference though.

For seperate workers, you need to configure your workers to use a special password (the VIP password).  You can find it either by looking at the p2pool log output as it starts up, or look at the contents of the file ./p2pool/data/bitcoin/vip_pass

Then there will be graphs per worker (worker name is whatever you are using for username).

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.

[Andrew Vorobyov]

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)
