Welcome to the home page of the MVAPICH project, led by Network-Based Computing Laboratory (NBCL) of The Ohio State University. The MVAPICH2 software, supporting MPI 3.1 standard, delivering the best performance, scalability and fault tolerance for high-end computing systems and servers using InfiniBand, Omni-Path, Ethernet/iWARP, and RoCE networking technologies. This software is being used by more than 2,600 organizations in 81 countries worldwide to extract the potential of these emerging networking technologies for modern systems. As of Jun '16, more than 379,000 downloads have taken place from this project's site. This software is also being distributed by many vendors as part of their software distributions.
The MVAPICH2 software is powering several supercomputers in the TOP500 list. Examples (from the June '16 ranking) include:
- 12th, 462,462-core (Stampede) at TACC
- 15th, 185,344-core (Pleiades) at NASA
- 31st, 74,520-core (Tsubame 2.5) at Tokyo Institute of Technology
