I'm trying to set up 2-4 Debian boxes at school to run in parallel under lam (MPI) and have several problems frustrating me. The machines are currently Not recognized by their names (eg. dasher.myschool.edu ) but rather only by IP address. We have a DHCP-based network, and I have the ISC dhclient running. The lam daemon requires the ability to rsh into the other nodes. But I need a password to access the other systems. We are on a token-ring network.
Is it possible to get the systems recognized by their names? IP addresses change under this system at times, so names make it easier ... Is there a way to get a password sent over to the other system when the lam daemon is connecting? (I recognize this likely belongs elsewhere, but I don't fully understand the workings of rsh access and thought there might be another way to surmount this problem?? This is the first time I've ever set something like this up ...) Does anyone have experience with MPI and know if lam is a good choice? Appreciate any help! Thanks! Kenward Vaughan
