automatic testing for MPI bugs

Open mabarnes opened this issue 11 months ago • 1 comments

We should add to the wish list an extension of the automatic tests to repeat cases on both a single processor and multiple processors to check for MPI errors.

This is technically already included. The automatic python tests are run by default on 4 processors. But they are also run once on a single processor (see the last test in the screenshot). If stella passes the tests on 1 processor but fails on 4 processors, it is clear that there is an MPI bug. But perhaps you'd like it to be more explicit?

I will close this issue, since tests are already run on 1 and 4 processors, which should reveal MPI bugs.
