        When migrating UNIX- and Linux-based HPC applications to Windows, the programmer has two choices:

        • Migrating to native Windows
        • Migrating to Subsystem for UNIX-based Applications (SUA)

        Although not providing full access to the rich Windows application execution environment, SUA can provide a relatively easy migration of UNIX applications with little code change required. The migration of the core MPI code of an HPC application is greatly simplified by the inclusion of MS Message Passing Interface (MPI) as part of Microsoft Windows Compute Cluster Server 2003. MS MPI is based on and compatible with MPICH2, the most widely used MPI implementation, while providing improved security and job management capabilities.

        This paper provides details on the two available migration paths.
