Bitweasil is the primary developer on the open source Cryptohaze tool suite, which implements network-clustered GPU accelerated password cracking (both brute force & rainbow tables). He has been working with CUDA for over 4 years (since the first public release on an 8800GTX), OpenCL for the past 2 years, and enjoys SSE2 as well. Bitweasil also rescues ferrets.
