Subject: rar-opencl performance
However while john is now running, I'm not entirely convinced it's
making any use of the GPU. I'm not seeing any GPU utilization from
john (really 0%), and performance is only slightly better than running
with the CPU (~800 p/s versus 250 p/s, using an i7-8700, a quick test
with cRARk tells me my GPU should be able to reach ~18,000 p/s. Of
course we're looking at different softwares but still). John also uses
the same number of OpenMP threads (12) on both runs
