The following communications libraries and acceleration packages are part of this Mellanox HPC-X® package:

Library/Acceleration Package

Version Number

Open MPI

4.1

Mellanox Scalable Hierarchical Aggregation and Reduction Protocol (SHARP)

3.1

HCOLL

4.8

UCX

1.14

UCC

1.2

nccl-rdma-sharp-plugin3

2.2

  1. Full Open SHMEM v1.4 support is available only if compiled with C11 Standard (see Rebuilding Open MPI from HPC-X™ Sources).

  2. ClusterKit is a multifaceted node assessment tool for high performance clusters.

  3. nccl-rdma-sharp plugin enables RDMA and Switch-based collectives (SHARP) with NVIDIA's NCCL library.

Warning

When HPC-X is launched with Open MPI without a resource manager job environment (slurm,pbs, etc.), or when it is launched from a compute node, the default rsh/ssh-based launcher will be used. This launcher does not propagate environment variables to the compute nodes. Thus, it is important to ensure the propagation of LD_LIBRARY_PATH variable from HPC-x is done as follows.

%mpirun -x LD_LIBRARY_PATH -np 2 -H host1,host2 $HPCX_MPI_TESTS_DIR/examples/hello_c

The following table lists the supported operating systems and CPUs for the latest HPC-X.
