[mpich2-dev] running mpich2 single pc dual core machine

[Rajeev Thakur]

On a single PC, you just need to do "mpd &". Only a single mpd daemon is
needed for all processes on that machine.

Hi All,

I have one question regarding running 2 processes in a single pc dual core
machine:

if I have two (one core) pcs I start the mpich with : mpdboot -n 2 -f
~/mpd.hosts

with mpd.hosts contents: node0

                                      node1

How can I use mpdboot in a single pc with dual core in order to have the
same effect above.

Is using : mpdboot -n 1 ~/mpd.hosts -ncpus=2 a correct approach ?

 (in the last case mpd.hosts contents is just : node0).

Any comment would be very helpful.

Alex
