[OpenMP][libomp] Enable HWLOC topology detection of multiple CPU kinds

2021-11-17T22:30:18+00:00

Teach the HWLOC topology method how to detect Atom and Core
types so hybrid CPUs are properly detected and represented when using
the HWLOC topology method.

[OpenMP][libomp] Improve Windows Processor Group handling within topology

2021-11-17T22:29:01+00:00

The current implementation of Windows Processor Groups has
a separate topology method to handle them. This patch deprecates
that specific method and uses the regular CPUID topology
method by default and inserts the Windows Processor Group objects
in the topology manually.

Notes:
* The preference for processor groups is lowered to a value less than
  socket so that the user will see sockets in the KMP_AFFINITY=verbose
  output instead of processor groups when sockets=processor groups.
* The topology's capacity is modified to handle additional topology layers
  without the need for reallocation.
* If a user asks for a granularity setting that is "above" the processor
  group layer, then the granularity is adjusted "down" to the processor
  group since this is the coarsest layer available for threads.

[OpenMP][libomp] Add support for offline CPUs in Linux

2021-11-17T22:28:01+00:00

If some CPUs are offline, then make sure they are not included in the
fullMask even if norespect is given to KMP_AFFINITY.

[OpenMP][libomp] Allow users to specify KMP_HW_SUBSET in any order

2021-11-17T21:27:37+00:00

Remove restriction forcing users to specify the KMP_HW_SUBSET value in
topology order. This patch sorts the user KMP_HW_SUBSET value before
trying to apply it. For example: 1s,4c,2t is equivalent to 2t,1s,4c

Revert "[openmp] Add OMPT initialization in libomptarget"

2021-11-10T11:44:25+00:00

Reverting initial OMPT for target implementation in favor of a
different implementation.

This reverts commit 3bc8ce5dd718beef0031bf4b070ac4026e6910d7.

[OpenMP] libomp: Fix handling of barrier pattern environment variables

2021-11-08T12:01:26+00:00

It is better to set all barrier patterns to use "dist" when at least
one environment variable specifies "dist". Otherwise if only one
environment is set to "dist" and others left blank inadvertently,
it would result in mixing dist barrier with default hyper barrier
pattern.
