Version 20110325 is a good 5%-10% slower on my 2nd and 3rd card compared to version 20110311.

On the contrary, on my 2x5970 Linux mining rig, no difference in hashspeed compared to older versions. Everything works fine.

Crossfire disabled?

Hi does anyone know if the accepted shares should be shown?

I am running solo with the latest poclbm client and unlike mining in pool the command prompt doesn't show any accepted shares or rejected shares. Is this normal?

Cheers!

There are no shares when mining solo, only found blocks.

i have a drop of ~2000 khash/s on 6950 and ~1000 khash/s on 5970 and 5870, nothing major, not even 1%

Not sure if this was discussed before, I didn't find anything on my 5 seconds search. I needed to use ssl for remote miners and while bitcoind now supports that out of the box, poclbm didn't seem to, at least not the version I was using (and I'm too lazy to try and upgrade a perfectly running system) so here's a patch to allow for that. Patch is for BitcoinMiner.py and you just supply the host part with 'https://' prefix to make it use ssl.

Code:
158,159c158,162
<
< self.host = '%s:%s' % (host.replace('http://', ''), port)
---
> if host.find('https:') >= 0:
> self.connector = httplib.HTTPSConnection
> else:
> self.connector = httplib.HTTPConnection
> self.host = '%s:%s' % (host.replace('http://', '').replace('https://', ''), port)
220c223
< self.connection = httplib.HTTPConnection(self.host, strict=True, timeout=5)
---
> self.connection = self.connector(self.host, strict=True, timeout=5)

try sdk 2.2 instead

Using SDK 2.2 instead of 2.3 or 2.4, I still get 2 cores put to 100% load using a HD 5870 and HD 5670 on Win7.

For the meanwhile anyone with this problem can set CPU affinity to only 1 (same for all) core for all poclbm processes so only one core is fully loaded, that way less electricity is used and less heat is made until a proper solution arises.. it doesn't seem to effect hash rate at all.

A while ago I installed opensuse 11.4, what exactly I need to do to use poclbm? The source only has 4 files and no makefile.

Doesn't look like a graceful shutdown to me Tongue

I'm getting a crash on Mac OS X 10.6.7 with m0mchil-poclbm-b981138. It doesn't crash with m0mchil-poclbm-74a5442.

I've posted the stack trace here:
https://gist.github.com/902241

I'm running it like this:

python poclbm.py -o deepbit.net -p 8332 -u <email> --pass=<password> -d 0 -f 120

This is with Python 2.6.6 installed from MacPorts. All dependencies were also installed from MacPorts.

Anyone else running into this and found a fix?

Hi,

I have a HD5850, and installed the AMD STREAM SDK 2.2.
But whenever i try to launch the miner i get my cpu's being used at 100% and no activity from the GPU.

Quote
Q: Why it uses 100% CPU?

You probably selected the CPU as OpenCL device. Or you are using it on Linux with AMD Stream SDK 2.2. Use 2.1 instead.

So how do i select the GPU as OpenCL device?

thank you.

EDIT: never mind just changed -d 0 to -d1 and the gpu was used.

Is there an option to limit the usage of the GPU to 50%?

Oddly, now it's working fine for me with b981138.

AMD 5xxx and up
use '-v -w 128'

Hi miners!

This should be "-v -w 128" or "-v -w128" without quote of course?

how do i run it on mac?



This is what I had to do.

Download and install Xcode

Install MacPorts from: http://www.macports.org/install.php

Install the dependences for poclbm. This step may take a long time while it downloads and compiles stuff:

sudo port install py26-pyopencl

Download the sources for m0mchil-poclbm, from https://github.com/m0mchil/poclbm

then open a terminal and extract it, and give it a try.

mkdir Bitcoin
cd Bitcoin
tar zxvf ~/Downloads/m0mchil-poclbm-b981138.tar
cd m0mchil-poclbm-b981138/
python2.6 poclbm.py -d 0 -o yourfavoriteminer -p 8332 -u user@example.com --pass=something

Be aware, that for what ever reason, OS X is FAR slower for mining than Linux or Windows. I run this on a Mac Pro with a pair of ATI Radeon HD 5770s. In OS X I get about 65Mhash/s on one and 95Mhash/s on the other. I installed  Ubuntu 10.10 and boot into it through Bootcamp. There I get 170Mhash/s on each card, over 2x the performance.
