True.. MY context is for use with MPI on a 10 (eventually 20) node cluster that works within it's own private network. I set it up with ssh as a rsh replacement and that works fine, but i'm wondering how much the overhead really is... if it's not much i'll just keep it with ssh..
BK i was surprised to read from the old ssh faq... "Across a heavily loaded Ethernet, rc4 encryption together with compression may actually be faster than using rcp." so do u think ssh with rc4 crypto and compression could beat rsh/rcp?
