Hi @DennisMitchell : I think that if you add the following environment variable to the script above sometime prior to the execution step on line 5, it would enable multitasking within Chapel:

export QT_HWPAR=4

(or 2 or whatever number of threads you are comfortable with -- this is essentially overriding the amount of thread-level parallelism supported by our threading layer by default). Let me know if you'd prefer to get feedback like this via a PR rather than a comment.

Hi @DennisMitchell: Here are the additional changes I believe we'll want in order to enable GASNet to run in an "oversubscribed locales" mode (multiple processes on the one server node):

export GASNET_SPAWNFN=L
export GASNET_ROUTE_OUTPUT=0
export GASNET_QUIET=Y

Respectively, these tell GASNet to:

  • spawn the processes locally
  • route all console output back to the original process
  • squash warnings saying "this isn't a smart mode to use GASNet in for performance"

I think that these should be sufficient, though there may be other system-specific settings we need to make.

The test of this step (which I'm happy to do if you like) is to take a multi-locale code like the one you cut and pasted from the chapel.cray.com front page last time and:

  • add --comm=gasnet to the compilation flags
  • add -nl 2 to the execution flags
