mbpr-osx:src magnum$ GWS=0 LWS=0 STEP=512 ../run/john -t -fo:sha256crypt-opencl -device=1
OpenCL platform 0: Apple, 2 device(s).
Using device 1: GeForce GT 650M
Building the kernel, this could take a while

Max local work size 1024, Optimal local work size 32
(to avoid this test on next run, put "sha256crypt_LWS = 32" in john.conf, section [Options:OpenCL])
Calculating best global work size, this will take a while
