... so it is waiting for the kernel to finish running on the GPU but that never happens because Windows killed the process. Reduce the sieve_size by 1 and see if that solves the problem. If not, reduce it some more.

It happens very rarely, but when and if not at the machine, you're loosing a lot of crunching time. Thus I'll follow your advice. Thanks!

Sometimes tasks are running 'endless' not using the GPU:

@Crystal: I had the same error
<message>
(unknown error) - exit code -1073741819 (0xc0000005)
</message>


Just solved upgrading to the latest Catalyst driver (had 14.4 before)

@valterc: That did the trick. Thanks.
Now finding the optimal config.

With both applications

collatz_sieve_1.21_windows_x86_64__opencl_amd_gpu.exe
collatz_sieve_1.21_windows_intelx86__opencl_amd_gpu.exe

I only get errors after a few seconds runtime

2 example results:

http://boinc.thesonntags.com/collatz/result.php?resultid=21771768

I have MS Visual C++ x86 and x64 installed. Already tried resetting and detaching the project without success.


Try using sieve_size=26
29 may have worked in the previous version because it really only ran 0.25 * sieve size per kernel whereas v1.20 runs the entire sieve for each kernel.

sieve_size=26 doesn't help either.

Even with an empty config, the task ends into an error. It's only lasting a bit longer:

Versions 1.04 up to 1.08 were working on my ATI 7770 where 1.04 was the very best version.

Since 1.09 only errors after a few seconds runtime:

The last 2 tasks:

Edit: Got the 32bit version 1.08 and now it's working again!

The same happened to me with the mini amd_gpu.exe
The start of the exe was blocked by Microsoft Security Essentials.
A week ago it was running normally, but this morning the very first task could not start due to:
