Hi, Kai,
Thanks for your note!
The available MPI_Info for DPM depends on launchers. As far as we known,
Hydra (mpiexec) does not support specifying outfile/errfile in MPI_Info.
Similarly, the support of multiple nodes in "host" info mentioned in
your previous post also depends on Hydra's implementation. You can
contact the MPICH team for additional details of Hydra.
