#2624: not possible to run tests *ony* on 2 (or more) MPI ranks

 Reporter: Roland Haas
   Status: new
Milestone: 
  Version: 
     Type: bug
 Priority: minor
Component: Cactus

A while ago Cactus' testsuite system gained the ability to run tests with “N” MPI ranks along with those requiring “N\+1” \(or greater\) MPI ranks. This has the side effect that it is impossible to run only the tests requiring “N\+1” ranks, since the “N” rank tests will always be included.

This is somewhat surprising and has lead to confusion about which tests are failing. A method to run only on the precise number of MPI ranks set in `CCTK_TESTSUITE_RPOCESSORS` \(or whatever it s name is\) should be provided, eg for use by the automated testing system \(which runs 1 and 2 ranks anyway to tests thorns that do not specify a preference for both numbers of MPI ranks\).
