I haven't tested all hashes but most of them works fine except the slow hashes which causes asic hangs most of the time with anything more than 1 thread feeding the GPU. You mean with all processes using one same GPU? On what branch was that? Recent improvements in raw-md4/md5 in bleeding-jumbo has reduced transfer latencies a lot so that approach should be less rewarding. magnum
