I followed the steps given here to setup up openMPI cluster : http://www.ps3cluster.umassd.edu/step3mpi.html My cluster consists of two nodes, master(192.168.67.18) and salve(192.168.45.65), connected directly through a cross cable.
After setting up the cluster n configuring the master node, i mounted /tmp folder of master node on the slave node(i had some problems with nfs at first but i worked my way out of it). Then i copied the 'pi.c' program in the /tmp folder and successfully complied it, giving me a binary file 'pi'. Now when i try to run the binary file using the following command #mpirun –np 2 ./Pi * * root@192.168.45.65's password: <it asks for the password> after entering the password it gives the following error: *bash: orted: command not found* *[ccomp.cluster:18963] [0,0,0] ORTE_ERROR_LOG: Timeout in file base/pls_base_orted_cmds.c at line 275* *[ccomp.cluster:18963] [0,0,0] ORTE_ERROR_LOG: Timeout in file pls_rsh_module.c at line 1166* *[ccomp.cluster:18963] [0,0,0] ORTE_ERROR_LOG: Timeout in file errmgr_hnp.c at line 90* *[ccomp.cluster:18963] ERROR: A daemon on node 192.168.45.65 failed to start as expected.* *[ccomp.cluster:18963] ERROR: There may be more information available from* *[ccomp.cluster:18963] ERROR: the remote shell (see above).* *[ccomp.cluster:18963] ERROR: The daemon exited unexpectedly with status 127.* *[ccomp.cluster:18963] [0,0,0] ORTE_ERROR_LOG: Timeout in file base/pls_base_orted_cmds.c at line 188* *[ccomp.cluster:18963] [0,0,0] ORTE_ERROR_LOG: Timeout in file pls_rsh_module.c at line 1198* *--------------------------------------------------------------------------* *mpirun was unable to cleanly terminate the daemons for this job.
