Subject: Re: [GSoC] John the Ripper support for PHC finalists

so I added cache for values to the previous version and now it's
(branch gpu4_cache)

[ run]$ ./john --test --format=pomelo-opencl --dev=3 --t_cost=2
Benchmarking: pomelo-opencl, POMELO [POMELO OpenCL (inefficient,
development use only)]... Device 3: GeForce GTX TITAN
Local worksize (LWS) 64, global worksize (GWS) 8192
Raw:    102400 c/s real, 101424 c/s virtual

if gpu isn't faster than cpu, implementing opencl to john the ripper
makes any sense?

why is only 1 GPU on super now?
