[openib-general] Announcing the release of MVAPICH-Gen2 1.0 (for OpenIB/Gen2 stack)

[Dhabaleswar Panda]

The MVAPICH team is pleased to announce the release of MVAPICH-Gen2
1.0 (for OpenIB/Gen2 stack) for multiple platforms (EM64T, IA-32 and
Opteron) and network interfaces (PCI-X and PCI-Express-including the
new mem-free cards and DDR technology).

With IBA 4X DDR technology, this release delivers the following
MPI-level performance:

    - 2.84 microsec one-way latency
    - up to 1474 MB/sec (unidirectional bandwidth)
    - up to 2645 MB/sec (bidirectional bandwidth)

Detailed performance numbers for other platforms are available on the
project's web page.

MVAPICH-Gen2 1.0 is available under BSD license.

A copy of this package will also be available from the OpenIB SVN
soon. As of this announcement, we are experiencing some technical
difficulties in uploading the code to the OpenIB SVN. We hope it to be
resolved soon.

This new release has a subset features of the popular MVAPICH 0.9.5
(over VAPI) package.  Successive releases will incorporate additional
features. Current features include:

      - optimized and tuned RDMA-based schemes for short 
                and long messages 

      - optimized intra-node shared memory support 
                (both for bus-based and NUMA-based systems)  

      - shared library support

      - optimized and tuned for the above platforms and different 
                 network interfaces (PCI-X and PCI-Express) and 
                 DDR technology

      - incorporates a set of tunable parameters  

      - support for multiple compilers

      - single code base for all of the above platforms

This release also includes an enhanced and detailed `User Guide' to
assist users to install this package on different platforms with
different options
