Thanx for all the input! Wow, I must say, you have been the most helpful linux distro author I've ever encountered! I really appreciate your help and my students will too!
OK, so I found your presentations page. I was looking at
http://www.pelicanhpc.org, but you meant
http://idea.uab.es/mcreel, right? I always used to go to
http://idea.uab.es/mcreel/ParallelKnoppix/ but not lately, so I forgot that address. I'm good now...
Now that I've booted n0-n3 I see what you mean by a single user system. This is the first time I ever got MPI working at school, so I don't know, is this the usual setup for MPI? I'm used to other clustering solutions, such as openMOSIX, where any node can be used to start a job. I see the compute nodes have a login screen, can anyone login there using the passwd I created at boot up to submit jobs? I suppose they would actually be controlling the master node remotely and perhaps lag a bit?
I had a problem with kernel_example. I got my 4 nodes up and ran kernel_example with no problem on the master node and saw all 3 graphs. My tic/tocs were 0.499, 0.070 and 3.335 respectively. Then I editted kernel_example to increase the number of compute nodes. No mater what I enter other than 0 (1, 2 or 3) octave hangs right after the first tic/toc and before the first plot. So, I'm not getting the compute nodes to work properly although they seem to have booted correctly as per your tutorial and ~/etc/bhosts lists them all....
Also, I'm wondering how octave knows where kernel_example.m is as it does not seem to mater what directory I'm in before I invoke kernel_example from octave and it still works fine (on n0 only)....
TIA,
AJG
