Had some errors too.

poclbm should had used a catch elseif for this error, to make more clear that something went wrong.
Or at least make it less scary, just make it print 'Could not fetch new work' Tongue

I'm running at ca. 42 Mhps on Mobility Radeon HD 5650, OpenCL SDK 2.3. Best options so far: -d 0 --user=XXX --pass=XXX -w 128 -v -f 5 (I'm not sure what does -f parameter do really, I'm a dummy).
Do you think that individual mining with laptop GPU is worth it? Note: I'm not paying for the electricity.
From what I've read, "-f x" is "framerate", i.e. the program will try to balance the kernel so that the kernel is run x times per second. This means that a lower value makes the kernel run for longer (-f 5 means the kernel takes about 0.2 seconds). If your OS feels sluggish (windows lag when you drag them on the desktop, videos seem choppy etc.) you can try to set -f higher. I use -f 120. At -f 60 I get slight lag when playing back HD videos, and the performance difference is only about 6% so I would much rather have a fully working machine. At -f 120 I notice no slowdown.

At least that is how I've understood it, I'm sure someone will correct me if I am wrong.

Edit: And if you're not paying anything for the electricity and it does not bother you to have it running in the background (presumably when the laptop is plugged in!) then it's free money, so why not? If you think bitcoin is interesting I see no reason why you wouldn't mine Smiley

@aistto

Switch crossfire off for now. Until I found why versions until and including 20101126 work with crossfire and later ones don't.

Using python 3.2 on windows  Undecided

No, no, no... use python 2.6

poclbm is not compatible with python 3. Actually python 2 and python 3 are quite different and not compatible with each other.

And what about version  20101126 and earlier? may be I could use it? where can I download it?

maybe you could, i wouldn't recommend it though if you don't really have to use it (have a 5970/dualGPU card)
on a 2x 5870 setup you can easily disable crossfire and use the latest miner-version on both cards.

if you want to use 20101126 anyway, here's a mirror.

Any advice on autostarting the miner when the computer boots up (without me logging in)? I configured bitcoind for autostart using this script from the forum.

I suppose for the miner I somehow need to configure envrionment variables (ATI Stream SDK) to be available upon boot. Plus it is confusing as I will start two instances of poclbm, one for each GPU I have.

I suppose I could still copy the script above in principle. One more problem, though: I think I want to pipe the verbose output of poclbm into a script that will parse and log the information, so I suppose I would start it like this

Quote
./poclbm.py -u somebody --pass=pwd -d 2 -v -w 128 --verbose | myparser.py

But what PID will be returned if I feed this to the start-stop-daemon command? If I use pipes, is the script I pipe into dependent on the originating script, that is, if I kill poclbm, will myparser.py also be killed?

Anything else I need to consider?

Thx!

Update: I just tried to start poclbm via ssh login from another computer. If the miner only shows the login screen, I get

Quote
No protocol specified
No device specified or device not found, use -d to specify one of the following

  •    Intel(R) Core(TM) i7 CPU         860  @ 2.80GHz
Once I log in to my account on the miner, I can also start poclbm via ssh.

What could be the reason? I don't suppose it is the environment variables, as they are configured in .bashrc. So I assume they should be known if I log in via ssh, too.

when I disable crossfire only first device is available. What should I do to use 2-nd?

aistto, see http://blog.zorinaq.com/?e=11

Initially, you can start the miner on first device, then connect your monitor to second device to make it available. If this seems too difficult, see above link for a way to keep second device always active. This is a windows only problem.

New version is up. Changes:

- handling httplib exceptions
- proper handling of wrong user name and password when mining with bitcoind
- support for more than one OpenCL platform
- caching kernel binaries for faster startup
- always flush stdout

I have no OpenCL support on my Gateway 450ROG with ATI Mobility Radeon 7500 laptop running Windows XP Pro, 32 bit.  As far as I can tell, I guess I can't run a GPU miner.  I tried downloading one, but it's only got linux programs in the zip file I downloaded, nothing for windows.  So, I don't get it.  I guess I'll just keep using the RPC Miner screensaver I downloaded and got working.

Hi all, the new version works perfectly, I've got 310-314Mhashes/s on my HD5870, but I've a noob question, if I run the program and stop a few hours later,  it resumed his calculations when he was stopped? Or I've to run it non-stop until having 50BTC?  (excuse my english ^^)

It's like playing the lottery every few seconds. Any one play can win the prize and subsequent plays aren't dependent upon previous plays. So, don't worry about turning it off whenever you don't want it on; everything will still average out.

Works great, m0mchil. Doing 48M on my GTX 460 with -v -f 90 (so I can use my desktop; I could get much more but I don't want to OC and I want to use my computer). It even continues doing 41M while WoW is running with no really discernible loss in frame rate.

My only question is, What's your address? I want to send you some bitcoins! Even though I'm sure you don't need them Cheesy

Right. Anyone else experiencing this problem?

Sys Specs:
Python 2.6.1
PyOpenCL 0.92 built from source
ATI Radeon HD 5750
Mac OS X 10.6.6 (Snow Leopard)

Command Line:
python poclbm.py -v -u xxx -p xxx -d 0

Bug / Error (repeats over and over until I ^C):
Code:

Buddy... I'm using Mac which is based on the UNIX backend. It's strictly python or shell for me, no .exe's.
