Hi Will,
            mpd is been replaced by hydra which is now the default process
manager for MPICH2. and if you want to verify whether mpich2 has been
installed then check whether 'mpiexec' , 'mpicc' are present, for this you
have to execute this command 'which mpicc' 'which mpiexec'.
And regarding the machinefile and executing MPI programs on a cluster follow
steps given in this link
http://wiki.mcs.anl.gov/mpich2/index.php/Using_the_Hydra_Process_Manager.

Regards,
-- Mahesh Doijade.

> Hi, I'm an amateur of Linux, and studying in Cluster with MPI recently. The
