The MVAPICH team is pleased to announce the availability of

  send queues for reduction in memory requirement on large scale
  clusters. This design also increases the small message messaging
  rate significantly. Available for Open Fabrics Gen2-IB.

  network congestion in large scale clusters. Available for 
  Open Fabrics Gen2-IB.

- RDMA CM based on-demand connection management for large scale
  clusters. Available for OpenFabrics Gen2-IB and Gen2-iWARP.

- uDAPL on-demand connection management for large scale clusters.
  Available for uDAPL interface (including Solaris IB implementation).
 
- RDMA Read support for increased overlap of computation and
  communication. Available for OpenFabrics Gen2-IB and Gen2-iWARP.

- Application-initiated system-level (synchronous) checkpointing in
  addition to the user-transparent checkpointing. User application can
  now request a whole program checkpoint synchronously with BLCR by
  calling special functions within the application. Available for
  OpenFabrics Gen2-IB.

- Network-Level fault tolerance with Automatic Path Migration (APM)
  for tolerating intermittent network failures over InfiniBand.
  Available for OpenFabrics Gen2-IB.
