Sun MPI and MPI I/O

Sun MPI is a highly optimized version of the Message-Passing Interface (MPI) communications library. Sun MPI implements all of the MPI 1.2 standard as well as a significant subset of the MPI 2.0 feature list. For example, Sun MPI provides the following features:

• Support for multithreaded programming.

• Seamless use of different network protocols; for example, code compiled on a Sun HPC cluster that has a Scalable Coherent Interface (SCI) network, can be run without change on a cluster that has an ATM network.

• Multiprotocol support such that MPI picks the fastest available medium for each type of connection (such as shared memory, SCI, or ATM).

• Communication via shared memory for fast performance on clusters of SMPs.

• Finely tunable shared memory communication.

• Optimized collectives for symmetric multiprocessors (SMPs).

• Prism support - Users can develop, run, and debug programs in the Prism programming environment.

• MPI I/O support for parallel file I/O.

• Sun MPI is a dynamic library.

Sun MPI provides full F77, C, and C++ support and Basic F90 support.
