You want me to detect where the mpich installation is?  The process manager is separate from the mpich installation.  It can be installed separately, and at a different location.  It has no idea where mpich is installed, or even if it’s mpich that it is interacting with.

Also, you want me to write things to a file and read them from all over the place?  Also, note that type sizes are not all.  You need the datatype layout as well.

Finally, suppose we run a program to generate this file.  How do we ship it around?  Scp?  stdout?

This solution is gross beyond imagination.  I’m not going to debate about it.
