MVAPICH Delivers Sub-minute (22 sec) Job Startup for 229,376 processes!! (Details)
Welcome to the home page of the MVAPICH project, led by Network-Based Computing Laboratory (NBCL) of The Ohio State University. The MVAPICH2 software, based on MPI 3.1 standard, delivers 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 2,950 organizations in 86 countries worldwide to extract the potential of these emerging networking technologies for modern systems. As of Nov '18, more than 506,000 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 family is ABI compatible with the version of MPICH it is based on. Please refer to our download page for more details.
The MVAPICH2 software is powering several supercomputers in the TOP500 list. Examples (from the Nov.'18 ranking) include:
- 3rd, 10,649,600-core (Sunway TaihuLight) at National Supercomputing Center in Wuxi, China
- 14th, 556,104 cores (Oakforest-PACS) in Japan
- 17th, 367,024 cores (Stampede2) at TACC
- 27th, 241,108-core (Pleiades) at NASA
- 69th, 76,032-core (Tsubame 2.5) at Tokyo Institute of Technology
