Hello all,
We''ve a cluster with 23 nodes connected to IB switch and 8 nodes
have connected to ethernet switch. Master node is also connected to IB
switch. SGE(with tight integration, -pe orte) is used for
parallel/serial job submission.
Open MPI-1.3 is installed on master node with IB support
(--with-openib=/usr). The same folder is copied to the remaining 23 IB
nodes.
Now what shall I do for remaining 8 ethernet nodes:
(1) Copy the same folder(IB) to these nodes
(2) Install Open MPI on one of the 8 eight ethernet nodes. Copy the
same to 7 nodes.
(3) Install an ethernet version of Open MPI on master node and copy to 8 nodes.
Which of the above could solve the SGE ethernet/IB parallel job submission?
Thanks,
Sangamesh
