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. It primarily aims at helping
|
|
applications with gathering information about modern computing
|
|
hardware so as to exploit it accordingly and efficiently.

Optional dependences:

numactl:
|
|
libnuma provides conversion helpers between hwloc CPU setsand
|
|
libnuma-specific types, such as bitmasks. It helps you use libnuma
|
|
memory-binding functions with hwloc CPU sets.
|
|
|
|
cudatoolkit:
|
|
CUDA enables interoperability with NVIDIA CUDA Driver and Runtime
|
|
interfaces. For instance, it may return the list of processors near
|
|
NVIDIA GPUs. Note that if I/O device discovery is enabled, GPUs may
|
|
also appear as PCI objects in the topology.
