Looks like I need to change the way it parses the config file. The log shows "reduction=" when I would expect it to have "kernels_per_reduction=". Because of that, your result is only using 16 instead of 256 kernels per reduction. I would expect it to be at least a little faster with 256 kernels per reduction which should also reduce the CPU time.


My config file:


items_per_kernel=20
kernels_per_reduction=8
threads=9
sleep=1


What do I have to change ??

Yes the CPU usage is 0.01 (previous usage 0,91), but now my 5970 doing WU 23xx-27xx sec. (previus 16xx sec). I wonder how many credits grants now.
btw 0,01 CPU usage is better ;]
