Re: [OMPI users] OPENSHMEM ERROR with 2+ Distributed Machines

[Debendra Das]

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.
