csWMPI II is an implementation of the complete Message Passing Interface (MPI) standard version 2.0. 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).

The new features of csWMPI II include dynamic process creation, parallel I/O, and one-sided communication that can be used on heterogeneous computations with processes running in MS Windows and Linux*. Due to these advanced features the core of csWMPI II has been completely rewritten to offer superior performance and stability.
