Hi Dmitry
As far as I know, MPICH-1 doesn't use the mpd daemon.

Why do you want to use MPICH-1?
It is not maintained anymore, and it uses the old P4 communication
mechanism that often hangs when running on current Linux kernels.

The MPICH developers recommend using MPICH2 instead:
"With the exception of users requiring the communication of
heterogeneous data, we strongly encourage everyone to consider switching
to MPICH2. Researchers interested in using using MPICH as a base for
their research into MPI implementations should definitely use MPICH2. "
(excerpt from http://www.mcs.anl.gov/research/projects/mpi/mpich1/)
OpenMPI and MPICH2 have more recent and more efficient
communication channels.
They will run your CFD code more efficiently,
and will keep you out of trouble:

My two cents.

Hi, all
During my postgraduate studies I take part in testing and, in future may be, in
development of CFD-suite of my professor. I know how to start daemon ring and
run an application on it in MPICH2, but:
1. I cannot do this on my PS3-cluster running YellowDogLinux because there's
OpenMPI only.
2. I cannot reproduce bugs in our suite when running MPICH-1.2.5 on EM64T
because I don't know how to install, start daemon ring running, and run an
application on it in MPICH-1.2.5.
So I'm interested in any advices how to install, run daemon ring, and run
application in OpenMPI and MPICH-1.2.5 when running any x64 Linux (CentOS,
Debian, OpenSuSE, etc.) or links on suitable documentation.
Thank you in advance.
