what?
I do have -D 0 present.

Thats the problem, a) it does not NEED -D at all, it was added by request for people who want to do split mining operations or leave GPUs unused, b) it starts at 1, not 0.

Update: Partially revert previous change, it doesn't work entirely right with vectors. Still moves 1 add to Java, though.

If you're using -v 2, try -v 3. If you're using -v 3, try -v 2.

Newb here.

When I run the windows.exe, I get a command line box with some text but it closes so quickly I cannot really read or type anything.

What am I doing wrong?

First off let me say thank you to DiabloD3 for putting so much time into this and offering so much help.  What a great service you have provided here!

I first learned of BitCoin about a week ago and I'm hooked and I'm determined to get my miner working.  I've spent hours reading first before posting my question...as any n00b should do.  So here's my question...

I'm getting this error: OpenCL platform AMD Accelerated Parallel Processing contains no devices

I've searched through the thread and found references to "ATI Stream contains no devices" but nothing like what I've pasted here.  The PC I'm running this on has an ATI Radeon 4670 but that doesn't seem to be the issue.

Any help or further documentation to what I currently have would be immensely appreciated!

Is there any way for this miner to work with intel opencl?

I should have said I'm running Windows 7 I suppose...

Diablo,

First off excellent miner and great work.  Java has far better multi-platform support than python, and the boost libraries that that pycl requires totally suck and are huge.  I hate boost.

Anyhow,  I'm consistently running into a strange issue with my dual 5830 setup using your miner.  After 4-5 hours of mining, one of the cores (random) will just stop.  The miner won't report any errors and the cumulative hashing average will continue to slowly drop.  In fact I get no other errors, can use all the aticonfig tools to manage the cores and simply restarting the miner seems to fix the problem.  The cores are overclocked (temps are ~70C under load) and I poll temps every minute using aticonfig.

Would it be worth adding some code to detect this stall?  Right now I just parse the GPU load output from aticonfig and restart the miners if it drops below a certain threshold.

I'm using the latest drivers and SDK.  I could not get the 2.1 SDK to work for the life of me in my environment, always "No OpenCL devices found" (or something to that effect). 

Also, to anyone else using the 5830: I seem to get best results with: -w 128 -f 1 -v 18


Thanks again!

Stalling cores could very well be a "normal" driver bug. It happens to some OpenCL users (isn't just my miner, but requires multiple GPUs), and I'm not sure why. Although almost every report I've heard I think involved using aticonfig to poll temps, so it might be related.

I used to have code that detected the condition, but I can't stop the threads for that GPU and it can lead to needing to reboot the machine because everything locked up if I try to "solve" it.
