1. At all nodes: cd $HOME touch .mpd.conf chmod 600 .mpd.conf nano .mpd.conf (if there's no nano - aptitude install nano) Enter in the file: MPD_SECRETWORD=_secretword_ _secretword_ must be the same at all nodes 2. At all nodes in /etc/hosts as root enter all nodes IP's, for the current node 127.0.0.1 change by its actual IP. 3. At head node run: mpd & mpdtrace -l Get _host_ _ _port_ 4. At slave nodes run mpd -h _host_ -p _port_ & 5. See if the daemon ring started by running mpdtrace Running mpiexec (2 examples) 1. mpiexec -machinefile /home/user/mfile -np 4 -wdir /home/user ./_YourCode_ The content of the file mfile: Slave0:2 Slave1:2 2 - number of cores 2. mpiexec -genv FOO BAR -n 2 -host Slave0 a.out : -n 2 -host Slave1 b.out FOO - environment variable BAR - its value a.out and b.out - executables. > Edited revision of original post without permission from author: > "Hello folks; > I want to make a cluster system employing the command/function: mpich, in > Ubuntu, but I am not too familiar with it.
