Release Notes: An SCTP channel has been added to the CH3 device. Infiniband hooks were added to the Nemesis channel. Speedups have been applied to collective communications and derived data types. Thread safety issues in the ch3:sock channel have been fixed. A fix for cross compiling with a C++ compiler was added. Numerous minor bugfixes and code cleanups were done.
Release Notes: This release adds bugfixes in relation to the release candidate.
Release Notes: This release adds high-performance MPI communication from NVIDIA GPU device memory (to/from other devices and host memory) with IPC, collectives ,and datatype support; CPU binding granularity at socket and numanode level; checkpoint-restart and run-through stabilization with Nemesis; suspend/resume; and enhanced integration with SLURM and PBS. Network Fault Resiliency (NFR) has been added.
Release Notes: This release fixes a data validation issue in GPU transfers, tunes CUDA block size to 256K for better performance, enhances error checking for CUDA library calls, and fixes a mpirun_rsh issue while launching applications on Linux Kernels.
Release Notes: This release adds iWARP interoperability between Intel NE020 and Chelsio T4 adapters, space optimization in regards to buffer usage, and MPI communication from NVIDIA GPU device memory (including intra-node point-to-point communication for multi-GPU adapters/node and RDMA-based inter-node point-to-point communication to/from GPUs). Optimizations for collectives and one-sided communication.
Release Notes: New features include improved support for fault tolerance, support for the ARMCI API, and non-collective group creation functionality. There are numerous bugfixes.
