High Performance MPI on Infiniband Cluster

Overview

The MVAPICH2 software, supporting MPI 3.0 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 2,600 organizations world-wide in 81 countries to extract the potential of these emerging networking technologies for modern systems.

Description

MVAPICH2 provides many features including MPI-3 standard compliance, single copy intra-node communication using Linux supported CMA (Cross Memory Attach), Checkpoint/Restart using LLNL's Scalable Checkpoint/Restart Library (SCR), high-performance and scalable InfiniBand hardware multicast-based collectives, enhanced shared-memory-aware and intra-node Zero-Copy collectives (using LiMIC), high-performance communication support for NVIDIA GPU with IPC, collective and non-contiguous datatype support, integrated hybrid UD-RC/XRC design, support for UD only mode, nemesis-based interface, shared memory interface, scalable and robust daemon-less job startup (mpirun-rsh), flexible process manager support (mpirun-rsh and hydra.mpiexec), full autoconf-based configuration, portable hardware locality (hwloc) with flexible CPU granularity policies (core, socket and numanode) and binding policies (bunch and scatter) with SMT support, flexible rail binding with processes for multirail configurations, message coalescing, dynamic process migration, fast process-level fault-tolerance with checkpoint-restart, fast job-pause-migration-resume framework for pro-active fault-tolerance, suspend/resume, network-level fault-tolerance with Automatic Path Migration (APM), RDMA CM support, iWARP support, optimized collectives, on-demand connection management, multi-pathing, RDMA Read-based and RDMA-write-based designs, polling and blocking-based communication progress, multi-core optimized and scalable shared memory support, LiMIC2-based kernel-level shared memory support for both two-sided and one-sided operations, shared memory backed Windows for one-Sided communication, HugePage support, and memory hook with ptmalloc2 library support. The ADI-3-level design of MVAPICH2 2.1rc1 supports many features including: MPI-2 functionalities (one-sided, dynamic process management, collectives and datatype), multi-threading and all MPI-1 functionalities. It also supports a wide range of platforms, architectures, OS, compilers, InfiniBand adapters (Mellanox and QLogic), iWARP adapters (including the new Chelsio T4 adapter) and RoCE adapters.
