MVAPICH: MPI over InfiniBand, 10GigE/iWARP and RDMAoE

MVAPICH2 powers China's First PetaScale System (NUDT Tianhe-1, 71,680-core with InfiniBand and the world's 5th ranked supercomputer) [more]
The number of organizations using MVAPICH/MVAPICH2 has crossed 1,000 world-wide. The MVAPICH team extends thanks to all these organizations.
Welcome to this web page related to `MPI over InfiniBand, 10GigE/iWARP and RDMA over Ethernet (RDMAoE)' project, lead by Network-Based Computing Laboratory (NBCL) of the Ohio State University. MVAPICH/MVAPICH2 software delivers best performance, scalability and fault tolerance for high-end computing systems and servers using InfiniBand, 10GigE/iWARP and RDMAoE networking technologies. This software is being used by more than 1,050 organizations world-wide (Current Users) to extract the potential of these emerging networking technologies for modern systems. This software is also being distributed by many InfiniBand, 10GigE/iWARP and RDMAoE vendors in their software distributions. MVAPICH and MVAPICH2 are also available with Open Fabrics Enterprise Distribution (OFED) stack. MVAPICH/MVAPICH2 software is powering several supercomputers in the TOP 500 list. Examples (from the Nov '09 ranking) include:
  • 5th, 71,680-core (Tianhe-1) at NUDT, China
  • 9th, 62,976-core (Ranger) at Texas Advanced Computing Center (TACC)
  • 27th, 18,224-core (Juno) at Lawrence Livermore National Laboratory (LLNL)
  • 48th, 18,176-core (Chinook) at Pacific Northwest National Laboratory (PNNL)
This project is currently supported by funding from U.S. National Science Foundation , U.S. DOE Office of Science, Ohio Board of Regents, ODOD , Cisco Systems, Intel, Linux Networx, Mellanox, QLogic, and Sun Microsystems; and equipment donations from Advanced Clustering , AMD, Apple, Appro, Chelsio, Dell, Fulcrum Microsystems, Fujitsu , Intel, Mellanox, Microway, NetEffect , QLogic and Sun. Other technology partner includes: TotalView Technologies. More details can be found here.
