Request to add oneTBB with hybrid processors support into Ubuntu native distribution channel

[Moskalev, Alexey]

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 this TBBBind 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 through https://help.ubuntu.com/community/Launchpad.
