I followed the steps given here to setup up openMPI cluster :
http://www.ps3cluster.umassd.edu/step3mpi.htmlMy 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

mpirun was unable to cleanly terminate the daemons for this job. Returned value Timeout instead of ORTE_SUCCESS.

I am totally lost now, as this is the first time i am working on a cluster project, and need some help
Thank you
