The MVAPICH team is pleased to announce the availability of MVAPICH
0.9.9-beta with the following NEW features:

- Message coalescing support to enable reduction of per Queue-pair
  send queues for reduction in memory requirement on large scale
  clusters. This design also increases the small message messaging
  rate significantly.

- Designs for avoiding hot-spots in networks of large-scale clusters

  - Multi-pathing support leveraging LMC mechanism
  - Multi-port support for enabling user processes to bind to 
    different IB ports for balanced communication performance
    on multi-core platforms

- Multi-core optimized scalable shared memory design

- Memory Hook support provided by integration with ptmalloc2 library. 
  This provides safe release of memory to the Operating System and
  is expected to benefit the memory usage of applications that 
  frequently use malloc and free operations.

- Optimized, high-performance shared memory aware collective
  operations for multi-core platforms

- Shared-Memory only channel (This interface support is useful for
  running MPI jobs on multi-processor systems without using any 
  high-performance network. For example, multi-core servers, 
  desktops, and laptops; and clusters with serial nodes.)

A new "Multiple-pair Bandwidth and Message Rate" test is also
available as a part of OSU_Benchmarks.
