Other releases
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.
