[petsc-users] How to pick up MPI implementation in PETSc

[Randall Mackie]

Dear PETSc team:

At the bottom of the configuration file, various things are printed out, like the MPI implementation:

MPI:
  Version:    3
  mpiexec: /state/std2/openmpi-5.0.3-oneapi/bin/mpiexec
  Implementation: openmpi
  OMPI_VERSION: 5.0.3
 
We would like to pick these up and write them to our own output files.

What PETSc variables have this information? 

Especially the implementation.


Thank you,

Randy M.
