python OpenCL bitcoin miner

[Tolsi]

I run bitcoin (bitcoin.exe -server), then I start poclb.exe, the poclb connected to my "bitcoin-server?

this means that I connect to my own server?

Where I see what I created?

excuse torture ...

If you register for pool.yyz.us and want to use it, you have to specify it  after "-host".
If you do not specify - connects to your personal server.
If you create block - you'll see it in your Bitcoin client (and get it after 100 (120?) confirmations).

Just a quick question here ,

I misunderstood the username & password part , is it the user name and password for the OS ? for this forum ?
Am confused a bit .

And by the way - what would be better KHash/s wise - a 2600k @ 5Ghz or a 5450 ?

Thanks ,

Danny.

Use any arbitrary combination. It’s just for the miner to communicate with your bitcoin client, so it doesn’t matter as long as they are identical at both places.

I got this error:
19/02/2011 18:10:44, verification failed, check hardware!

What does this mean? Did i find a block and it couldn’t be verified or was it just an attempt? It happened once in almost two hours, and for the first time now.

[Dude65535]

verification failed means the program though it found a block but after trying the hash again got a different result. Most likely that means you have your GPU overclocked too much.

When I try to set the .exe via command prompt to use my 6870 I get an error message.

IO:error errno 2 no such file or directory : bitcoinminer.cl



It is there though, tried putting poclbm in the bitcoin root and in a sepperate folder.

Is there a way to monitor this miner? Like I have it running on a PC in the cellar that I ssh into. Can I check the current hash rates and success rates somehow?

If you scroll up a few posts you will find the answer to my question about the miner sending an email every time it finds a block (and it's accepted). At least this way I know when a block was found. I think the best thing to do would be having some kind of an interface similar to the one bitcoind has (getbalance, getdifficulty etc.) - just having a few of such features on the miner would be cool (gethashrate, listfoundblocks etc.). As for the temperature (you were asking about it in the other thread) it's easy to check it via the aticonfig tool (unless you're using nvidia, I don't know how to do it for nvidia cards). You could have a script monitoring the output from: sudo aticonfig --odgc

The problem with that is when you login via ssh not all features of aticonfig work (they only work properly if you're using it directly from the machine which has the screen connected). I am sure Raulo will be able to shed some light here.

I am seeing this exact same error. Let me know if you solve it...

Everything works exactly the same with ssh as it works via console if you have DISPLAY=:0 set and you are the user that "owns" the display. If the latter is not fulfilled, being root and having DISPLAY=:0 is all you need.

the answer to my question about the miner sending an email every time it finds a block

I saw that, but I think it involves changing the code of poclbm? While doable, it would be a nuisance if new versions of poclbm appear and the modifications had to be repeated.

I think m0mchil mentioned something about hooks into poclbm?

@Raulo thanks for the info about the DISPLAY variable. I urgently need to get an understanding of that display stuff.

Do you know how to use git? You can make a modification in your copy and each time m0mchill changes poclbm, you simply pull git changes and if it does not conflict with your version, the changes apply without any fuss. This is a very convenient and standard way of keeping a fork of a program up to date.

[Fractality]

Yeah, I'll probably fork poclbm on GitHub.

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.

[thejode]

Ok, usually I start the miner on slush's server with regular settings, just not specifying the -w value.
I read about it somewhere else, so I decided to mess around with it.
I'm running a Nvidia GeForce 8600M GT, and generally get about 5000 khash/s without specifying the -w value.
Then, when I set -w to 512, I got a hash rate of 1880356953 khash/s! I'm pretty sure that's messed up. And it ran like that for about 30 seconds before it crashed.
Glitch....or what?
On win7, btw.

I too am getting intermittent errors while using slush's pool with win7-64:

Code:

Those are both from approximately around the same time, but each one occurred on its own graphics card (I am running 2 nvidia gtx 275 cards). It seems that they occur very chronologically close to one another. Further, it either occurs on only one card, or it happens on both of them, one within a few seconds of the other.

Here is another example, each paste is from a miner running on its own gpu:

I too am getting intermittent errors while using slush's pool with win7-64:

If you hit that before hour or two, I was upgrading the pool servers and many connections were cut.

Code:

BadStatusLine

This just means that data from connection were corrupted (probably because connection was forcibly closed) and poclbm don't catch it. It is just cosmetic.

Why?

sorry for my english:)

[CD-RW]

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'

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

@aistto

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

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.
