Package Information

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

USE Flags

Flag Description 2.12.2 2.11.2-r1
X use the X Window System ✓ ✓
cairo Enable the Cairo back-end of hwloc's lstopo command ✓ ✓
cpuid Enable the cpuid-based architecture specific support (x86 component) ⊕ ⊕
cuda Enable CUDA device discovery using libcudart ✓ ✓
debug Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces ✓ ✓
doc Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally ✓ ✓
l0 Enable oneAPI Level Zero device discovery ✓ ✓
nvml Enable the NVML device discovery ✓ ✓
pci Enable PCI device discovery using libpci ⊕ ⊕
rocm Enable AMD RSMI device discovery ✓ ✓
static-libs Build static versions of dynamic libraries as well ✓ ✓
svg Add support for SVG (Scalable Vector Graphics) ✓ ✓
udev Enable virtual/udev integration (device discovery, power and storage device support, etc) ✓ ✓
valgrind Enable annotations for accuracy. May slow down runtime slightly. Safe to use even if not currently using dev-debug/valgrind ✓ ✓
video_cards_nvidia Enable GL display device discovery (NVCtrl) ✓ ✓
xml use libxml2 for XML support, instead of a custom minimalistic support ✓ ✓
