  1. Add libpciaccess, a generic PCI access library 

    libpciaccess is a generic PCI access library originally developed for the
Xorg project; it is now used by various other projects, for example the
hwloc library developed by the OpenMPI project.

The upstream git repository is at
https://gitlab.freedesktop.org/xorg/lib/libpciaccess

To avoid the dependency on the "xorg-macros" autotool package, the CMSDIST
package for libpciaccess is based on the Debian package (where the autogen
step has already been performed) instead of the upstream git sources.

  2. Add numactl utilities and libnuma library version 2.0.14 

    Simple NUMA policy support. It consists of a numactl program to run
other programs with a specific NUMA policy and a libnuma shared library
("NUMA API") to set NUMA policy in applications.

See https://github.com/numactl/numactl/blob/v2.0.14/README.md for more
information.

  3. Add the Portable Hardware Locality (hwloc) package 

    The Portable Hardware Locality (hwloc) software package provides a
portable abstraction (across OS, versions, architectures, ...) of the
hierarchical topology of modern architectures, including NUMA memory
nodes, sockets, shared caches, cores and simultaneous multithreading.
It also gathers various system attributes such as cache and memory
information as well as the locality of I/O devices such as network
interfaces, InfiniBand HCAs or GPUs.

See https://www.open-mpi.org/projects/hwloc/ for more details.

  4. Add the NVIDIA GDRCopy library v2.1 

    GDRCopy is a low-latency GPU memory copy library based on NVIDIA
GPUDirect RDMA technology.

For more details, see
  - https://github.com/NVIDIA/gdrcopy/blob/v2.1/README.md
  - https://docs.nvidia.com/cuda/gpudirect-rdma/
  - https://developer.nvidia.com/gpudirect

Note: GDRCopy currently supports only x86 and Power archiectures.

  5. Add the UCX libraries version 1.9.0 

    Unified Communication X (UCX) provides an optimized communication layer
for Message Passing (MPI), PGAS/OpenSHMEM libraries and RPC/data-centric
applications.
UCX utilizes high-speed networks for inter-node communication, and
shared memory mechanisms for efficient intra-node communication.

For more information see
