I have installed OpenMPI-2.0.0 in 5 systems with IP addresses 172.16.5.29, 172.16.5.30, 172.16.5.31, 172.16.5.32, 172.16.5.33.While executing the hello_oshmem_c.c program (under the examples directory) , correct output is coming only when execution is done using 2 distributed machines.But error is coming when 3 or more distributed machines are used.The outputs and the host file are attached.Can anybody please help me to sort out this error?
Thanking You.
