[petsc-dev] Custom reductions

[Matthew Knepley]

I understood from Jed that MPIU_MIN and friends are for floating point, but
here


https://bitbucket.org/petsc/petsc/src/da407576a5bf29881cba0f2df6c198aa8caa98f0/src/sys/logging/plog.c?at=master#cl-1346

we use MPI_MIN. Is this wrong?

  Thanks,

     Matt
