MVAPICH2 drives 10th ranked 5+ Petaflop TACC Stampede system with 519,640 cores, InfiniBand FDR and Intel MIC [more]
Welcome to this web page related to "MPI over InfiniBand, 10GigE/iWARP and RDMA over Converged Ethernet (RoCE)" project, lead by Network-Based Computing Laboratory (NBCL) of The Ohio State University. The MVAPICH2 software, supporting MPI 3.0 standard, delivers best performance, scalability and fault tolerance for high-end computing systems and servers using InfiniBand, 10GigE/iWARP and RoCE networking technologies. This software is being used by more than organizations world-wide in 79 countries (Current Users) to extract the potential of these emerging networking technologies for modern systems. As of , more than downloads have taken place from this project's site. This software is also being distributed by many InfiniBand, 10GigE/iWARP and RoCE vendors in their software distributions. The MVAPICH2-X software package provides support for hybrid MPI+PGAS (UPC and OpenSHMEM) programming models with unified communication runtime for emerging exascale systems. The MVAPICH2-GDR package provides support for clusters with NVIDIA GPUs supporting the GPUDirect RDMA feature. The MVAPICH2-Virt package provides support for high performance and scalable MPI in a cloud computing environment with InfiniBand and SR-IOV. The MVAPICH2-MIC package provides support for clusters with Intel MIC coprocessors. MVAPICH2 software is powering several supercomputers in the TOP 500 list. Examples (from the Nov '15 ranking) include:
- 10th, 519,640-core (Stampede) at TACC
- 13th, 185,344-core (Pleiades) at NASA
- 25th, 76,032-core (Tsubame 2.5) at Tokyo Institute of Technology
