Subject: sha512crypt-opencl gives CL_INVALID_COMMAND_QUEUE
Hello,
I have tried to benchmark opencl performance of sha512crypt.
The cuda was faster than my CPU at least in 1.8.0-jumbo1, but recommends
opencl that should be even faster (for md5crypt, it is).
However the sha512crypt-opencl procudes errors, I was unable to help with
LWS and GWS settings.
Any idea what can be wrong? the standard output of git clone below:
% ./john -test -format=sha512crypt-opencl
