MPICH2 64-bit

MPICH2 64-bit is a high-performance, portable implementation of the Message Passing Interface (MPI) standard. It is developed and maintained by Argonne National Laboratory, a leading research center in the United States.

With MPICH2 64-bit, users can run parallel programs on systems that support MPI, including clusters of workstations and supercomputers. It supports a wide range of operating systems, including Windows, Linux, and macOS.

The software provides many features that enable efficient and scalable parallel computing. These include support for MPI-3 features such as non-blocking collectives and neighborhood collectives, as well as optimized collectives for specific network interconnects.

• It is fully compliant with the MPI-2 and MPI-3 standards
• Supports shared-memory parallelism using OpenMP
• Implements multiple network APIs, including TCP/IP and InfiniBand
• Provides tools for performance analysis and tuning such as the MPICH performance model
• Includes support for hybrid programming models combining MPI and OpenMP or MPI and CUDA

MPICH2 64-bit is a reliable and powerful tool for parallel computing that is trusted by many researchers and institutions worldwide.
