The MVAPICH team is pleased to announce the availability of MVAPICH2-1.0-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. Available for Open Fabrics Gen2-IB. - Hot-Spot Avoidance Mechanism (HSAM) for alleviating 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. - Integrated multi-rail communication support for OpenFabrics Gen2-iWARP. - Blocking mode of communication progress. Available for OpenFabrics Gen2-IB. - Based on MPICH2 1.0.5p4.
