Configuration
add MPICH2 binary path to your PATH
export PATH=/cworkspace/ifp-32-2/hasegawa/pineking/programs/mpich2/bin:$PATH
Check we can find them:
which mpd which mpiexec which mpirun
MPI expects the configuration file in your home directory named /home/you/.mpd.conf (/etc/mpd.conf if root). It should contain one line:
secretword=<secretword>
where <secretword> is a password, that should not be your user password. Make it readable/writable only by you:
chmod 600 .mpd.conf
