The following communications libraries and acceleration packages are part of this Mellanox HPC-X® package:
Library/Acceleration Package | Version Number |
Open MPI | 4.1.x |
Mellanox Scalable Hierarchical Aggregation and Reduction Protocol (SHARP) | 2.6 |
HCOLL | 4.7 |
UCX | 1.14 |
UCC | 1.0 |
Open SHMEM specification compliance | 1.41 |
ClusterKit2 | 1.6 |
nccl-rdma-sharp-plugin3 | 2.1 |
Full Open SHMEM v1.4 support is available only if compiled with C11 Standard (see Rebuilding Open MPI from HPC-X™ Sources).
ClusterKit is a multifaceted node assessment tool for high performance clusters.
nccl-rdma-sharp plugin enables RDMA and Switch-based collectives (SHARP) with NVIDIA's NCCL library.
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.
Starting from HPC-X v2.9, HPC-X will no longer support PPC architecture.
