Hi, 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: Host: server1.tm.local Executable: a.out Cannot continue. 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. -- GAURAV GUPTA B.Tech III Yr. , Department of Computer Science & Engineering IT BHU , Varanasi Contacts Phone No: +91-99569-49491 e-mail : gaurav.gu...@acm.org gaurav.gupta.cs...@itbhu.ac.in 1989.gau...@gmail.com
