Nerd is an attempt to create a cross-platform scripting language that is based on Scheme and easy to embed, extend, and use. It's currently used in video game projects and is interpreted only. There are definite future plans to add a byte-code compiler and VM to it and to write proper documentation.
Wisecracker is a 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.
