Please test, and report results from devices other than Bull's. Thank you for working on that. I'll send test results withing few hours. > For some reason it segfaults on the Tahiti (but not on AMDAPP/CPU). On all other devices I've tried it works fine. If we can get this straight we should implement similar changes to a bunch of other OpenCL formats that use PBKDF2-HMAC-SHA1. On Tahiti it segfaults during selftest, testsuite or some real world cracking? > These are massive changes to both host code and kernel. Some 15-20% boost is gained too btw, and device auto-tuning is implemented. 15-20% just for nvidia or for amd too? Lukas
