Resolving The Problem
How do I run intel mpi jobs?
First, you need to source intel mpi's environment setup script, e.g.
# . /opt/intel/mpi/3.0/bin64/mpivars.sh
1- mpd ring startup :
1.1 $HOME/.mpd.conf creation :
echo "password=anything_you_want" > $HOME/.mpd.conf
chmod 600 $HOME/.mpd.conf
1.2 hostfile creation :
For example : file called hostfile contains the following :
-----------
compute-0-0
compute-0-1
-----------
1.3 start the ring :
mpdboot -n 2 -r ssh -f hostfile
1.4 check the ring :
mpdtrace -l
should give you something like this :
--------------------
compute-0-0_32834
compute-0-1_32811
--------------------
2- compile your program and then run the job : mpiexec -np 2 ./testf77
shoule give you an output like this :
------------------------------------------------------------------------
Hello world: rank 0 of 2 running on
compute-0-0
Hello world: rank 1 of 2 running on
compute-0-1
------------------------------------------------------------------------
