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. |
