[mpich-discuss] Configuration options request

These options have to do with how MPI processes communicate with the 
process manager and its proxies. Typically, MPI processes communicate 
over a Unix socket with the process manager or proxy.

--enable-allowport makes it so TCP/IP communication can also be used for 
this feature. This option only applies to the gforker and remshell 
process managers (--with-pm=gforker,remshell).

--enable-pmiport applies to the Hydra process manager, but is 
conceptually the same.

Hope this helps.
