[Dhabaleswar Panda]

The MVAPICH team is pleased to announce the release of MVAPICH 1.2RC1
with the following NEW features:

- New Features for OpenFabrics Gen2-IB Interface

  - Network Fault Resiliency (NFR) for tolerating
    transient network failures.  Using this
    feature, long running MPI codes can
    tolerate network failures.  InfiniBand
    HCAs are automatically reset and MPI
    programs can continue computation
    without having to restart.

  - Support for RDMA over Ethernet (RDMAoE) for
    ConnectX-EN adapter.

This version has also the following bugfixes and enhancements
compared to the 1.1 release.

  - Totalview usage (thanks to Adam Moody at LLNL)
     - Enable Totalview with -tv
  - Registration cache
     - Turn off registration cache if ptmalloc is turned off
