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:
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.
