I'm not optimistic. Now i can segfault the compiler using my best code for NVIDIA. And I do compile only. I checked on bull CPU, NVIDIA and 7970. It is the SAME source code, i even removed #defines, #ifdefs, etc. The source: opencl_build_kernel("$JOHN/cryptsha512_kernel_NVIDIA.cl", gpu_id); exit(0); // <== --- The result is: (and i did nothing or am i crazy? Not that crazy at least) OpenCL platform 1: AMD Accelerated Parallel Processing, 2 device(s). Using device 0: Tahiti Segmentation fault (core dumped) --- So i will: - try your PUTCHAR macro. - do the final test and ajustment. - create and submit a patch. - and than come back to 7970. At this time, we might have a better 12.04 driver. If we have a new version: - I can remove the support to AMD GPU (using nice warning message). - I can remove the support to southern island AMD GPU (idem). BTW: the NVIDIA code gives me more than 3500 c/s. It is not that bad. Claudio
