Dear all,

I have installed lustre on 4 nodes, all on same network.
I want to run IOR benchmark on the setup.

I have tested the mpi ring by using the following commands:

mpd &
mpiexec -n 1 /bin/hostname

output: hp01 (local machine name)
sudo nano mpd.hosts :- updated the clients here (2 clients hp01 hp02)
mpdboot -n 2 -f mpd.hosts


expected. 2 clients(hp01 hp02)


mpiexec -n 30 /bin/hostname

ouput: prints hostname hp01 15 times hp02 15 times:


*When I run IOR on this setup using:mpirun -np 2 Gadre/IOR/src/C/IOR -f
Gadre/IOR/scripts/testScriptI get following error:IOR-2.10.3: MPI
Coordinated Test of Parallel I/ORun began: Mon Mar 16 15:16:00 2015Command
