Ok, I haven't looked at that in any detail. Any reason why the fix can't be done in the program itself? The other OpenCL apps are well behaved. Is there anything fundamental about Genefer that prevents the same behavior?

I just noticed this yesterday running GFN-17 and GFN-17MEGA. nearly equal CPU time vs run time in Linux.

Judging from Iain's post here, he was looking into it.
But that post was 60 days ago, so I don't know if it's moving along. Either way, Iain is the person to implement this.

Ok. Maybe we need input from creator(s) of AP27. That one uses very little CPU. PPS-sieve also, but I think that one is CUDA.

EDIT:- GFNSvOCL as well with the help of W1 flag (I don't have direct experience running it, but saw it in the forums)
