Unfortunately I had trouble installing wifi drivers for Ubuntu (then I had a libssl-dev conflict when trying to build john) and I'm not at home until tomorrow, so I can't report on the Linux results yet. I did some more performance tests with the -te flag this time. Here are some results showing OpenCL (HD 7670M) against my CPU (i5-3210M) OpenCL's results md5crypt: 40046 c/s wpapsk: 4050 c/s phpass: 254015 c/s raw-md5: 32750K c/s raw-sha1: 18881K c/s CPU's results: md5crypt: 20941 c/s wpapsk: 1070 c/s phpass: 11239 c/s raw-md5: 19254K c/s raw-sha1: 14691K c/s I am interested in getting OpenCL working on cygwin.

The AMD APP SDK was installed previously and the correct enviromental variables were set, but I didn't do anything specific to Cygwin. For example this command compiles AMD's HelloWorld sample: g++ -I"$AMDAPPSDKROOT/include" -L"$AMDAPPSDKROOT/lib/x86" HelloWorld.cpp -lOpenCL -o HelloWorld.exe I'll report back when I have Linux results.
