WMPI from the Instituto Supererior de Engenharia de Coimbra, Portugal is a full implementation of MPI for Microsoft Win32 platforms. WMPI is based on MPICH and includes a P4  device standard. P4 provides provides the communication internals and a startup mechanism. The WMPI package is a set of libraries (for Borland C++, Microsoft Visual C++ and Microsoft Visual FORTRAN). The release of WMPI provides libraries, header files, examples and daemons for remote start-up. WMPI can co-exist and interact with MPICH/ch_p4 in a cluster of mixed UNIX and Win32 platforms. WMPI is still under development and freely available. WMPI and other MPI environments for NT had been explored thoroughly in a previous project .
