hwloc (Hardware Locality) 2.4.0 is now available for download.
https://www.open-mpi.org/software/hwloc/v2.3/
v2.4.0 is a small release that mainly brings support for hybrid CPUs
through a new API in hwloc/cpukinds.h.
The following is a summary of the changes since v2.3.0.
Version 2.4.0
-------------
* API
+ Add hwloc/cpukinds.h for reporting information about hybrid CPUs.
- Use Linux cpufreq frequencies to rank cores by efficiency.
- Use x86 CPUID hybrid leaf and future Linux kernels sysfs CPU type
files to identify Intel Atom and Core cores.
- Use the Windows native EfficiencyClass to separate kinds.
* Backends
+ Properly handle Linux kernel 5.10+ exposing ACPI HMAT information
with knowledge of Generic Initiators.
* Tools
+ lstopo has new --cpukinds and --no-cpukinds options for showing
CPU kinds or not in textual and graphical modes respectively.
+ hwloc-calc has a new --cpukind option for filtering PUs by kind.
+ hwloc-annotate has a new cpukind command for modifying CPU kinds.
* Misc
+ Fix hwloc_bitmap_nr_ulongs(), thanks to Norbert Eicker.
+ Add a documentation section about
"Topology Attributes: Distances, Memory Attributes and CPU Kinds".
+ Silence some spurious warnings in the OpenCL backend and when showing
process binding with lstopo --ps.
There are no changes since 2.4.0rc2.
