[Dhabaleswar Panda]

The MVAPICH team is pleased to announce the release of MVAPICH 1.1RC1 with
the following NEW features:

- New Features for OpenFabrics Gen2-IB Interface
  - eXtended Reliable Connection (XRC) support
  - Lock-free design to provide support for asynchronous
    progress at both sender and receiver to overlap
    computation and communication

- New OpenFabrics Gen2-Hybrid interface
  - Replaces the Gen2-UD interface of MVAPICH 1.0 series
  - Targeted for large-scale IB clusters (multi-thousand cores) to
    provide highest performance and minimal memory usage
  - Support for UD, RC and XRC transports
  - Adaptive selection during run-time (based on application and
    systems characteristics) to switch between RC and UD
    (or between XRC and UD) transports
  - Delivers performance and scalability with near constant
    memory footprint for communication contexts
  - Zero-copy protocol with UD for large data transfer
  - Multiple buffer organizations with XRC support
  - Shared memory communication between cores within a node
  - Multi-core optimized collectives
    (MPI_Bcast, MPI_Barrier, MPI_Reduce and MPI_Allreduce)
  - Enhanced MPI_Allgather collective
