I am new to mpi programming and openmpi. I have installed openmpi and run
several sample programmes on single machine. But while running on several
nodes it is showing errors.
I have configured openmpi and automated login to all nodes with user mpi.
Now on master i tried to run by "mpiexec -np 4 -host n1,n2,n3,n4 a.out"
where n1,n2,n3 and n4 are four nodes on which i have enabled automatic
login. Now I am getting error :
Failed to find the following executable:
Now my problem is this should I copy this executable to all nodes ??? If yes
then how will it work, because I am not expecting any value from user all
parameters are generated in a.out itself.
Please help me out what is the problem here and what should i do.
Thanks in advance.
