Development of computational performance evaluation testing

• ...

GNU-10 compatibility

• GNU 10 much stricter w.r.t. argument mismatches, so far we had to add compiler flags to turn them into warnings (bad)
  • use mpi or include mpif.h don't work w/o these flags; need to use use mpi_f08
  • this turns the MPI communicator into a DDT (no longer an integer), does the framework support this w/o a definition of the DDT?
  • Does use mpi_f08 work with all systems that need to be supported

Dictionary of standard names

Transition to capgen.py
