--restart Reload the myrinet driver the mappernode to completely clear stale routes Simply does the following: /cluster/rte/rte stop /cluster/rte/rte start


NOTES

Use the "--restart" option if you are re-mapping the network after major changes to it or you have selected a new mapper node.

Map, route, and host files are written to /tmp/gm_mapper/ on the mappernode. If you want to use them for "file mapping", rcp or scp them to the admin node and put them in /cluster/rte/<vmname>/config.
