Hello,
What is the content of your devices.txt
file? Based on the reported error (CL_INVALID_WORK_GROUP_SIZE) it seems that the globalWorkSize
is invalid for your GPU.
Regards
--- Edit
I've just seen it at the end of your message.
Please test with powers of 2 at first for globalWorkSize
and localWorkSize
values (1024 / 128).
Hi,
so you mean 2, 4, 8, 16, 32, ... ? The 980
and 132
came from the setup
command as recommended values, maybe you can check this?
Yes. The setup command can only guess optimal values depending on your GPU memory, compute cores and logical groups sizes. However, many cards have physical restrictions that OpenCL can't see. Based on community tests we somehow figured out that multiples of 2 have a better chance of success. I've added a suggestion in the setup manual (https://github.com/bhamon/gpuPlotGenerator#setup).
A power of 2 did work here. Thank you. :-) BTW: How much HDD is minimum recommended? And creating plots this way is a bit complicated as you cannot set plotsize=512G
for 512 GByte plot size. But it is okay, time to find the optimal value out. :-)
I'm getting this error message with latest
