[openib-general] Announcing the availability of MVAPICH 0.9.8-rc0 with on-demand connection management, fault-tolerance and adavanced multi-rail scheduling support

[Dhabaleswar Panda]

The MVAPICH team is pleased to announce the availability of MVAPICH
0.9.8-rc0 with the following new features:

  - On-demand connection management using native InfiniBand 
    Unreliable Datagram (UD) support. This feature enables InfiniBand 
    connections to be setup dynamically, enhancing the scalability 
    of MVAPICH on multi-thousand node clusters. 

  - Support for Fault Tolerance: Mem-to-mem reliable data transfer
    (detection of I/O bus error with 32bit CRC and retransmission in
    case of error). This mode enables MVAPICH to deliver messages
    reliably in presence of I/O bus errors.

  - Multi-rail communication support with flexible scheduling policies:
      - Separate control of small and large message scheduling
      - Three different scheduling policies for small messages: 
            - Using First Subchannel, Round Robin and Process Binding 
      - Six different scheduling policies for large messages: 
            - Round Robin, Weighted striping, Even striping, 
              Stripe Blocking, Adaptive Striping and Process Binding

  - Shared library support for Solaris 

  - Integrated and easy-to-use build script which automatically
    detects system architecture and In.niBand adapter types and
    optimizes MVAPICH for any particular installation
 
More details on all features and supported platforms can be obtained
