csWMPI is an implementation of the complete Message Passing Interface (MPI) standard version MPI-1.2. It is a software development kit, which enables the development and deployment of parallel applications for MS Windows and Linux platforms on x86 and x86_64 (AMD64) architectures.

Starting at csWMPI 1.6, the csWMPI is a light version of csWMPI II, binary compatible with the previous csWMPI 1.5 versions. These new versions ensure users access to the latest enhancements on performance, platform support and usability of the csWMPI II premium product, although limited to MPI-1.2 features.
