> > The MVAPICH team is pleased to announce the availability of > MVAPICH2-1.0 with the following NEW features: > > - Message coalescing support to enable reduction of per Queue-pair > send queues for reduction in memory requirement on large scale > clusters. This design also increases the small message messaging > rate significantly. Available for Open Fabrics Gen2-IB. > > - Hot-Spot Avoidance Mechanism (HSAM) for alleviating > network congestion in large scale clusters. Available for > Open Fabrics Gen2-IB. > > - RDMA CM based on-demand connection management for large scale > clusters. Available for OpenFabrics Gen2-IB and Gen2-iWARP. > > - uDAPL on-demand connection management for large scale clusters. > Available for uDAPL interface (including Solaris IB implementation). > > - RDMA Read support for increased overlap of computation and > communication. Available for OpenFabrics Gen2-IB and Gen2-iWARP. > > - Application-initiated system-level (synchronous) check-pointing in > addition to the user-transparent check-pointing. User application > can now request a whole program checkpoint synchronously with BLCR > by calling special functions within the application. Available for > OpenFabrics Gen2-IB. > > - Network-Level fault tolerance with Automatic Path Migration (APM) > for tolerating intermittent network failures over InfiniBand. > Available for OpenFabrics Gen2-IB. > > - Integrated multi-rail communication support for OpenFabrics > Gen2-iWARP and RDMA CM (with Gen2-IB). > > - RDMA based Direct One-sided communication support for OpenFabrics > Gen2-iWARP and RDMA CM (with Gen2-IB). > > - Blocking mode of communication progress. Available for OpenFabrics > Gen2-IB. > > - Based on MPICH2 1.0.5p4. > > 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 1.0 is tested with OFED 1.1, OFED 1.2 and OFED 1.2.5 (for > ConnectX). It continues to deliver excellent performance. Sample > performance numbers include: > > OpenFabrics/Gen2 on EM64T quad-core with PCIe and ConnectX-DDR: > Two-sided operations: > - 1.66 microsec one-way latency (4 bytes) > - 1405 MB/sec unidirectional bandwidth > - 2716 MB/sec bidirectional bandwidth > > One-sided operations: > - 3.19 microsec Put latency > - 1405 MB/sec unidirectional Put bandwidth > - 2716 MB/sec bidirectional Put bandwidth > > Performance numbers for all other platforms, system configurations and > operations can be viewed by visiting `Performance' section of the > project's web page. > > For downloading MVAPICH2 1.0 package and accessing the anonymous SVN, > please visit the following URL: > > http://mvapich.cse.ohio-state.edu/ > > All feedbacks, including bug reports, hints for performance tuning, > patches and enhancements are welcome.
