My network administrator noticed similar things coming from my small cluster. After a bit of investigation, it seems that if a node goes down in a Mosix cluster, all the other nodes arpflood with who-has requests. It became such a pain that I only enable the cluster after working hours, so as not to flood others' connections. While on the subject of mosix, same network admin mentioned that MPI/PVM may run into trouble on the cluster. Any thoughts on that? Regards, Edward. -- http://www.pcug.org.au/~edlang/
