Threading Environment Variables
===============================

  :header-rows: 1

  * - Variable
    - Description
  * - ``OMP_NUM_THREADS``
    - Sets the maximum number of threads to use for OpenMP parallel regions.
  * - ``MKL_NUM_THREADS``
    - Sets the maximum number of threads to use for the Intel MKL library. Note that MKL_NUM_THREADS takes precedence over ``OMP_NUM_THREADS``.
Add doc page for environment variables that effect PyTorch Runtime (#119087) # Summary The goal of this PR is to add a doc page to list a number of environment that effect the PyTorch runtime. It will likely not be exhaustive but hopefully will be added and updated to stay relevant.
