ive searched for an answer here, and couldnt find it.
I own a macbook pro, which has a core 2 duo processors, that means i can have 1 machine with 2 nodes, right?
Ive set it all up, like it says in the manual, but resource manager registers a localhost machine with only one node.
ive read i need to edit the openmpi_default_hostfile... i did try it, but what ever i type, number of nodes doesnt change.
i tried: localhost nodes=2
i tried something like this (in PTP FAQ):
"Simulating multiple nodes with OpenMPI: If you are testing on a single node, edit <openmpi_install>/etc/openmpi-default-hostfile (default is /usr/local/etc/openmpi-default-hostfile) and add lines containing 'node0', 'node1', etc. Edit /etc/hosts and add a localhost entry for each name you added to the openmpi-default-hostfile. So, for 'node0', add '127.0.0.1 node0' to /etc/hosts. This will simulate a multi-node machine."
nothing could recognize the second node.
thank you for your time
