Bug Fix - Fix numa error on grace cpu in gpu-copy

[dpower4]

The current GPU Copy BW Performance fails on Nvidia Grace systems. This is due to the memory only numa node and thus the numa_run_on_node fails for such nodes and halts completely.

This fix checks for the presence of assigned CPU cores for the numa node, on checking if it has no cpu cores assigned, it skips that specific node during the args creation and continues.

   Project, including but not limited to communication on electronic mailing lists, source code control
   systems, and issue tracking systems that are managed by, or on behalf of, the Project for the purpose of
   discussing and improving that Project, but excluding communication that is conspicuously marked or

   Submission is made in the course of Your work for an employer or Your employer has intellectual
   property rights in Your Submission by contract or applicable law, You must secure permission from Your
   employer to make the Submission before signing this Agreement. In that case, the term “You” in this
   Agreement will refer to You and the employer collectively. If You change employers in the future and

  Submission to reproduce, prepare derivative works of, publicly display, publicly perform, and distribute
  the Submission and such derivative works, and to sublicense any or all of the foregoing rights to third
  parties.
• Patent License. You grant Microsoft, and those who receive the Submission directly or
  indirectly from Microsoft, a perpetual, worldwide, non-exclusive, royalty-free, irrevocable license under

  Submission with the Project to which it was Submitted to make, have made, use, offer to sell, sell and
  import or otherwise dispose of the Submission alone or with the Project.

   licenses. You represent that each of Your Submissions is entirely Your original work (except as You may
   have disclosed under Section 3). You represent that You have secured permission from Your employer to

Thanks for the fix! I left one minor comment.

One major concern: with current fix, the dtoh/htod performance regarding to those non-CPU NUMA nodes are just skipped. We need to find a way to allocate memory buffers in non-CPU NUMA nodes (instead of current numa_run_on_node) and get these dtoh/htod tests done.

@dpower4

Totally Agree. This case should only occur in case of single socket grace machines. will need a work around to handle the setting of node affinity for such nodes. Will work in it and create a separate PR.
