Wisecracker is an open source high performance distributed cryptanalysis framework that leverages GPUs and multiple CPUs. It allows security researchers to write their own cryptanalysis tools that can distribute brute-force cryptanalysis work across multiple systems with multiple multi-core processors and GPUs. Security researchers can also use the sample tools provided out-of-the-box. The differentiating aspect of Wisecracker is that it uses OpenCL and MPI together to distribute the work across multiple systems, each having multiple CPUs and/or GPUs. As an example an MD5 reversing for 6-8 character strings is provided. More information including source code, technical papers and API documentation can be found at http://selectiveintellect.com/wisecracker.html Thanks.

I don't think this statement on your website makes much sense: A user can download Wisecracker™ on a GPU cluster virtual machine provided by Amazon EC2® and reverse an MD5 cryptographic hash for a 6 character password in about 20 minutes if using 1 virtual machine or in about 3 minutes if using 2 or more. What does "2 or more" mean here? If I use two machines in parallel, that's more than six times as fast as only using one machine? Seems weird to me.
