[petsc-users] mpi with different OS(CentOS and macOS)

[Jed Brown]

Probably, but it's fragile in that you need to use separate executables and you'd launch something like

  mpiexec -n 1 ./app-linux : -n 1 ./app-osx

provided you have identical MPI versions and the same app configuration compiled on each platform.
