HPC-X General Support
The platform and requirements for HPC-X are detailed in the following table:
Platform | Versions |
CUDA | 12.3+ |
GDRCopy | 2.3+ |
DOCA-Host | 3.0.0 |
NCCL | 2.22+ |
NVIDIA BlueField-3 | 32.45.1020 |
NVIDIA ConnectX-5/ConnectX-5 Ex | 16.35.2000 |
NVIDIA ConnectX-6 | 20.43.1014 |
NVIDIA ConnectX-6 Dx | 22.45.1020 |
NVIDIA ConnectX-6 Lx | 26.45.1020 |
NVIDIA ConnectX-7 | 28.45.1020 |
NVIDIA ConnectX-8 | |
XPMEM | 2.7 |
Grace-Hopper - GH200 | N/A |
The following communications libraries and acceleration packages are part of this NVIDIA HPC-X® package:
Library/Acceleration Package | Version Number |
Open MPI | 4.1 |
NVIDIA Scalable Hierarchical Aggregation and Reduction Protocol (SHARP) | 3.12.0 |
HCOLL1 | 4.8 |
UCX | 1.19.0 |
UCC | 1.5.0 |
Open SHMEM specification compliance | 1.42 |
ClusterKit3 | 1.15 |
nccl-rdma-sharp-plugin4 | 2.7 |
ncclnet_plugin | 1.1.0 |
OSU Micro-Benchmarks | 7.4 |
HCOLL is not supported on GB200 and GB300 systems, with no plans for future support.
Full Open SHMEM v1.4 support is available only if compiled with C11 Standard.
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.
