The MVAPICH team is pleased to announce the availability of MVAPICH
1.0-beta with the following NEW features:
- New OpenFabrics Gen2 Unreliable-Datagram (UD)-based design
for large-scale InfiniBand clusters (multi-thousand cores)
- delivers performance and scalability with constant
memory footprint for communication contexts
- zero-copy protocol for large data transfer
- shared memory communication between cores within a node
- multi-core optimized collectives
(MPI_Bcast, MPI_Barrier, MPI_Reduce and MPI_Allreduce)
- New features for OpenFabrics Gen2-IB interface
- support for asynchronous progress at both sender and receiver
to overlap computation and communication
- support for ConnectX adapter
- multi-core optimized collectives (MPI_Bcast)
- tuned collectives (MPI_AlltoAll, MPI_Bcast)
based on network adapter characteristics
- network-level fault tolerance with Automatic Path Migration (APM)
for tolerating intermittent network failures over InfiniBand.
- enhanced coalescing support with varying degree of coalescing
- enhanced mpirun_rsh to provide scalable launching on
multi-thousand node clusters
- New Support for Qlogic InfiniPath adapters
- high-performance point-to-point communication
- optimized collectives (MPI_Bcast and MPI_Barrier) with k-nomial
algorithms while exploiting multi-core architecture
