if MPSD_MICROARCH is not defined, use archspec to determine

Hans Fangohrrequested to merge
more-robust-micro-architecture-detection into main

What does the MR provide?

  • If MPSD_MICROARCH is not defined as a environment variable, then use archspec to determine it.
  • if archspec is not available, ask user to provide it via error message and stop.

Where does this matter?

  • script creates a folder for the microarchitecture.
  • Found in Docker container that this would be dev-23a/UNKNOWN_MICROARCH/
  • the same will happen on other user machines (unless they are the Linux laptops provided by MPSD; but we know several people who prefer to run their own distribution, or even non-linux system (i.e. Mac).
