[openib-general] Announcing the release of MVAPICH 0.9.7 with support for Gen2, SRQ with Flow Control, Fault Tolerance and anonymous SVN access

[Dhabaleswar Panda]

The MVAPICH team is pleased to announce the release of MVAPICH 0.9.7
with the following new features:

 - Shared Receive Queue (SRQ) support with flow control: The new
   design uses significantly less memory for MPI library - less than
   300MBytes of MPI internal buffers per process for clusters with 16K
   processes!!  Performance benefits of the proposed scheme for sample
   applications (HPL and NAS LU) can be obtained from MVAPICH project's
   page -> Performance.

 - OpenIB/Gen2 support: All features (such as RDMA-based collectives,
   multi-rail, scalable MPD-based startup, etc.) available with VAPI are
   now available with OpenIB/Gen2.

 - MVAPICH-Gen2 also enables the use of IBM ehca adapter and 
   PathScale adapter through OpenIB/Gen2 support
 
 - Support for Fault Tolerance: Mem-to-mem reliable data transfer
   (detection of I/O bus error with 32bit CRC).  Additional fault
   tolerance support (such as checkpoint restart, automatic path
   migration (APM), etc.) will be introduced in successive releases.

 - Advanced AVL tree-based Resource-aware registration cache

 - Tuning and Optimization of various collective algorithms for a wide
   range of system sizes

 - Multi-rail communication: Various schemes (Multiple queue pairs per
   port, Multiple ports per adapter, and Multiple adapters).  Flexible
   scheduling policies: round-robin for small and non-blocking
   communication and striping for large blocking communication
 
MVAPICH 0.9.7 release supports Gen2, VAPI and uDAPL transport
interfaces. It also has support for the standard TCP/IP (provided by
MPICH stack). It is tested with the following architecture, OS,
compilers and InfiniBand adapters:

  - Architecture: EM64T, Opteron, IA-32, IBM PPC and Mac G5 
  - Operating Systems: Linux, Solaris, AIX and Mac OSX 
  - Compilers: gcc, intel, pathscale and pgi 
  - InfiniBand Adapters: 
       - Mellanox adapters with PCI-X and PCI-Express 
         (SDR and DDR with mem-full and mem-free cards) 
       - PathScale adapter (through OpenIB/Gen2 support) 
       - IBM ehca adapter (through OpenIB/Gen2 support)

More details on all features and supported platforms can be obtained
by visiting the project's web page -> Overview -> features.

MVAPICH 0.9.7 is being distributed as a single integrated package
(with MPICH 1.2.7 and MVICH).  It is available under BSD license.

Starting with this 0.9.7 release, MVAPICH team is also pleased to
announce the availability of the code base through anonymous SVN
access. Nightly tarballs are also available. A new mvapich-commit
mailing list has been established for users, developers and vendors to
keep track of all commits happening to the SVN. (SVN access to
MVAPICH2 code base will be coming soon.)

MVAPICH 0.9.7 continues to deliver excellent performance.  Performance
numbers for all platforms and system configurations and operations can
be viewed by visiting `Performance' section of the project's web page.

An enhanced and detailed `User Guide' is now available (in both html
and pdf forms) from the FAQ page.

For downloading MVAPICH 0.9.7 package and accessing the anonymous
SVN, please visit the following URL:

A stripped down version of this release is also available at the
OpenIB SVN.

All feedbacks, including bug reports, hints for performance tuning,
patches and enhancements are welcome. Please post it to the newly
established mvapich-discuss mailing list.

Thanks,
