  • Initial support for vector collectives in the NCCL and MPI backends: Allgatherv, Alltoallv, Gatherv, Scatterv, and Reduce_scatterv.
  • Added new benchmarks for all supported operations.
  • Improved performance and correctness of the spin-wait kernel used in the host-transfer backend.
  • Improved progress engine binding logic. Related environment variables have been removed. Failing to bind no longer throws an exception.
