There are three commands with which a OpenSees job can be launched.

  • OpenSees: For running a job in serial (single CPU).
  • OpenSeesSP: Intended for the single analysis of very large models.
  • OpenSeesMP: For advanced parametric studies.

More info can be found about running OpenSees in parallel here.

Single process with a single thread. Usually submitted as part of an array, as in the case of parameter sweeps.
