>
> 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.

> 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.
