I did everything you said! OK, this is exactly what I did to try to netboot over the LAN (no crossover cable as of yet):
(1) boot master node with a 64bit pelicanHPC 1.7 CD
(2) run pelican_start script and get up to the screen where you hit "yes" if all compute nodes are found or you hit "no" to find more compute nodes (0 compute nodes at this point)
(3) set up BIOS for net boot on a compute node
(4) initiate PXE boot on compute node
(5) hit "no" several times on master node but still get 0 compute nodes! Sometimes, several IPs are listed on master node: something like master 10.11.12.1 cannot reach 10.11.12.2, 10.11.12.3, etc.
That's it, I was trying to connect only 2 PCs over the LAN (one master node and one compute node)! However, eventaully the PXE boot times out on the compute node and it ends up booting the CD. To add insult to injury, not that it maters really, but both PCs are right next to eachother on the LAN and still cannot connect as a pelicanHPC cluster???
BTW, should I try the lastest version of your CD instead? I think that is version 1.8, right?
Also, just curious, do you find 64bit performance significantly improved over 32bit? I know that a 64bit architecture will have larger maxint and memory address spaces, but is there a gain in thruput as well?
TIA,
