so i followed the guide for windows and got my local machine to mine and run p2pool, but how would i point my other machine running bamt to it? i tried using the username:password i setup in the rpc conf and pointed it to 127.0.0.1:9332, yes the ports open, but it did nothing. thanks in advance

127.0.0.1 is a special address for localhost

127.0.0.1 on your other machine is look back at itself not looking at the machine running p2pool.

you just need to replace 127.0.0.1 with the local IP address of the machine running p2pool. likely it is 192.168.x.x

127.0.0.1 is the wrong IP address if you are trying to point a miner on a different machine to your windows p2pool node. 127.0.0.1 is "localhost" and always refers to the local computer you use it on. You need to use the IP address or hostname of your windows machine: mywindowsmachine:9332 or x.x.x.x:9332

Look what I mean. Using the latest cgminer:
--intensity 6 --gpu-threads 1

--intensity 6 --gpu-threads 2
http://img526.imageshack.us/img526/3117/2th.png

Thats like 10% slower.

you should speed up your fans to above 4000RPM so your cards cool of to <80°C. Your cards will live a lot longer with lower temperatures.
try:

Code:

--auto-gpu --auto-fan

note that when you compare hashrates, with "--auto-gpu" cgminer takes a few minutes after restart untill gpus run at full load. It slowly increases clocks in the beginning.

You are right. 2 threads is better. I see at least 5% improvement. Raising intensity didn't work for me, whole thing started to throttle down.

1 thread
Total rate: 3.22G, stale rate: 35M

2 threads
Total rate: 3.42G, stale rate: 55M

DiabloMiner uses 3, it isn't a settable option. This is for a reason.

What is that reason?

Because drivers suck dick. I thought it was self evident.

Using "--gpu-threads 1" isn't at all essential for P2Pool. I get fine reject rates without it.

There's an optimum point that balances between a lower rejection rate and a lower hash rate, you just have to find it. However, you might be below that point.. maybe try dropping --gpu-threads 1 or a slightly higher intensity. (Bitcoin has a balance in the same manner, it's just at a very different point since work needs to be updated every 10 minutes instead of 10 seconds.)

Why is your intensity a 6? Try an 8. multiple threads hides the latency in such a tiny batch size (intensity sets how many nonces are check in one "batch").

Also 90C? Wow. Not good for GPU longevity.

My GPU makes 300MHash/s in solo (2 threads) and 285MHash/s in p2pool (1 thread). Thats 5% slower. Does that mean I lose 5% revenue compared to solo mining?

This implies you're using the pool to measure mhash: DO NOT DO THIS. This is measured by shares submitted, which is a random event. The ONLY true measurement of mhash is the miner itself.

Yes but I don't show a lower hashrate (well maybe <2% lower) but that might just be noise. I consider the 1%-2% worth it for the reduced variance (and the support it provides other miners who wouldn't choose solo over conventional pool).

I always had this loss when comparing a centralized pool and p2pool. Now, with the newest miner version (poclbm here, cgminer soon), both number are now the same and even a little higher than before!
So, what miner and which version are you using? Used options?

Stability is the next issue.

I agree with you Kano, I think it's time to start working on documentation.
I know that it's often easier to write the perfect program (forrestv) than its documentation.
While working on the documentation reveals a much more good ideas to ensure network stability.

I'm glad you volunteered to write the documentation, now get cracking, I expect it done by the end of the week.

Not a chance I'm gonna read thousands and thousands of lines of python to try and work out how this works Tongue

forrestv gets paid for p2pool - he should do it Tongue

Yes, and its also open source. Don't like it? Change it.

Eh? What's that got to do with documentation?
Or did you mean that the source is there so anyone who doesn't have a life can document it? Tongue

Though I did mention to forrestv ... a few times ... quite a while back that I need to read the code ...
But in the end, it's too much effort IMO for someone who didn't write any of it (and I'm certainly not a python guru Tongue

)
