Subject: Re: OpenCL performance numbers on Radeon HD 5870
I was able to compile the code on OSX Lion. As Crypt is not part of OSX, I only tested the PHPASS hash.
./john -test -format:PHPASSOPENCL
Benchmarking: PHPASSOPENCL [PORTABLE-MD5]... end read_kernel_source
OpenCL Device: ATI Radeon HD 5670
setup context
build kernel
end build program
DONE
Raw: 52306 c/s real, 1774K c/s virtual
