Quite interesting! Exploitation of the impressive parallelism of graphical processor units (GPUs) for molecular simulations is gaining more and more attention from researchers. Nowadays it is easy to find in computer rooms NVIDIA GPUs programmable with the CUDA parallel language. Other applications of GPU parallelism are not only medical research but also common tasks such as videoediting, photoshop and… password recovery. For the last task, demo versions of the programs from Parallel Password Recovery are available for testing. I should try it on an old word document I have forgotten pass.
