Runtime error: assertion failed about gpuowl HOT 7 CLOSED

Could you please add what is on the previous output line? (there should be the name of the kernel concerned). In fact, it may be useful to add the full gpuowl output at the start, where it reports: exponent, fft-size, gpu model.

from gpuowl.

I am using the text console and have no means to copy the output. I will try to redirect it to a file.

from gpuowl.

You'll find it in gpuowl.log in the same folder. You can do something like:
"tail -n20 gpuowl.log > report.txt"
to get the last 20 lines in the .txt file.

Thank you for the help, here is the output:

Interesting.. I can't make sense of why that assertion fails. The numbers (WIDTH, HEIGHT, NW, NH) seems correct. The workgroup size for that kernel should be 256, and that assert should pass.

If you do a "git status" or "git diff", do you have local changes? or an old gpuowl.cl? Otherwise, I'm out of ideas on this.

Ok, I see what happens here.
I copied the new gpuowl executable in the directories but I still have the old gpuowl.cl
So stay tuned ...

After copying also the new gpuowl.cl it works now.
