The MVAPICH team is pleased to announce the availability of MVAPICH2-1.2 with the following NEW features:
- Scalable and robust daemon-less job startup - Enhanced and robust mpirun_rsh framework (non-MPD-based) to provide scalable job launching on multi-thousand core clusters - Available for OpenFabrics (IB and iWARP) and uDAPL interfaces (including Solaris) - Support for Totalview debugger - Checkpoint-restart with intra-node shared memory support - Allows best performance and scalability with fault-tolerance support - Enhancement to software installation - Full autoconf-based configuration - Automatically detects system architecture and adapter types and optimizes MVAPICH2 for any particular installation - An application (mpiname) for querying the MVAPICH2 library version and configuration information - Enhanced processor affinity using PLPA for multi-core architectures - Allows user-defined flexible processor affinity - Enhanced scalability for RDMA-based direct one-sided communication with less communication resource - Available for OpenFabrics (IB and iWARP) interfaces - Shared memory optimized algorithm for MPI_Bcast operation - Optimized and tuned MPI_Alltoall - Based on MPICH2 1.0.7 More details on all features and supported platforms can be obtained by visiting the following URL: http://mvapich.cse.ohio-state.edu/overview/mvapich2/features.shtml MVAPICH2 1.2 is being made available with OFED 1.4. It is also tested with OFED 1.3. It continues to deliver excellent performance. Sample performance numbers include: OpenFabrics/Gen2 on EM64T quad-core with PCIe-Gen2 and ConnectX-QDR: Two-sided operations: - 1.25 microsec one-way latency (4 bytes) - 2573 MB/sec unidirectional bandwidth - 5037 MB/sec bidirectional bandwidth One-sided operations: - 2.73 microsec Put latency (4 bytes) - 2576 MB/sec unidirectional Put bandwidth - 4921 MB/sec bidirectional Put bandwidth Performance numbers for several other platforms, system configurations and operations can be viewed by visiting `Performance' section of the project's web page.
