Subject: sha512crypt-opencl
Claudio, Gifts -
A while ago, atom let us know that his sha512crypt implementation in
oclHashcat-plus is "87% faster" than ours on NVIDIA's 560Ti. Gifts has
now benchmarked the two on his 560Ti, and at first glance this does not
appear to be the case - however, more testing is needed.

Gifts - can you please use -i=all8 for the actual run, and let it run
for 10 minutes? When you give no options, JtR uses "batch mode", which
includes a "single crack" mode phase. "Single crack" mode is
GPU-unfriendly. Besides, we currently include self-test duration in
total running time used for c/s rate calculation.
Thanks,
Alexander
