Subject: Re: OpenCL performance numbers on Radeon HD 5870
Compiles and runs fine on MacOS Lion (10.7). This is OpenCL v1.50.62.
./john -test -format:PHPASSOPENCL
Benchmarking: PHPASSOPENCL [PORTABLE-MD5]...
OpenCL Device: ATI Radeon HD 5670
DONE
Raw: 58251 c/s real, 1945K c/s virtual
./john -test -format:CRYPTMD5OPENCL

OpenCL Device: ATI Radeon HD 5670

While it compiles fine on MacOS Snow Leopard (10.6), it fails to run on it. This is OpenCL v1.5.6. See errors below.
