Here are my "achievements" during last week: -Sent gsoc forms to Google. -uploaded previous sha256cuda-0 patch to wiki. -finished work on 0 revision of cryptsha256cuda patch. -developed simple testing script for my patches -uploaded old patches benchmarks results collected from mailing list and contributors. And priorities for next one: -try profile patches on nVidia nSight MS Visual Studio patch -develop md5-based crypt cuda patch Comment: I am truly disappointed by perfomance of cryptsha256cuda patch. It is 8-10 slower than it should be. And only few times faster than cpu version. I tried some tricks but without a significant results. There must be a bottleneck in local memory load/store operations and I want try nVision profiler to seek them and destroy. Now I am moving for md5-based crypt rather than planned sha512-based crypt patch because it is easier and I don't want get into infinite optimization loop during premature sha512 coding. Lukas
