prov/gni: add ability to detect local PE rank #1405

Closed hppritcha closed 6 years ago

hppritcha commented 6 years ago

There may be some cases, when the GNI provider is being used in the context of a job launcher like SLURM or ALPS, that the provider may need to use the local rank of a process in deciding how to allocate Aries HW resources to the process.

This commit adds a function to determine the "local rank". This doesn't apply to processes not started via a SLURM or ALPS based launch.
