Hi,

I've made the preliminary change to enable hwloc support:
https://salsa.debian.org/science-team/tbb/-/commit/f9f0d2da2252bdb568dd975e809d6bd7c9d3fb6e
This will be included in the next upload.

Hello, dear Debian Science Maintainers.



I’d like to make request to add a new version of oneTBB with hybrid processors support into Ubuntu native distribution channel.

Current version of oneTBB in the distribution does not support hybrid arm based processors or Alder Lake<https://ark.intel.com/content/www/us/en/ark/products/codename/147470/products-formerly-alder-lake.html>.

According to the logs: |https://launchpadlibrarian.net/618963979/buildlog_ubuntu-kinetic-amd64.onetbb_2021.5.0-13_BUILDING.txt.gz:

-- HWLOC target HWLOC::hwloc_1_11 doesn't exist. The tbbbind target cannot be created

-- HWLOC target HWLOC::hwloc_2 doesn't exist. The tbbbind_2_0 target cannot be created

-- HWLOC target HWLOC::hwloc_2_5 doesn't exist. The tbbbind_2_5 target cannot be created

TBBBind library was not built.



To enable thisTBBBind build, please follow these instructions: https://github.com/oneapi-src/oneTBB/blob/master/cmake/README.md
Important things:

·        The oneAPI Threading Building Blocks (oneTBB) implementation requires the hwloc library to query NUMA(version >= 1.11) and Hybrid CPUs (version >= 2.4) topology information. HWLOC project: https://www-lb.open-mpi.org/projects/hwloc/

·        TBBBind library configuration:

     *   tbbbind links with HWLOC 1.11.x
     *   tbbbind_2_0 links with HWLOC 2.1–2.4
     *   tbbbind_2_5 links with HWLOC 2.5 and late

·        Automatic HWLOC searching requires CMake version 3.6 or higher.

·        HWLOC automatic search is managed through pkg-config



Please, let me know if you have any questions and if I need to submit this as a FR throughhttps://help.ubuntu.com/community/Launchpad.
