HPC-X Content
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 |
Open SHMEM specification compliance | 1.41 |
| ClusterKit2 | 1.8 |
nccl-rdma-sharp-plugin3 | 2.2 |
- 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.
Important Note
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
