Hi All!
I just saw the write-up Pelican HPC got in Linux Pro magazine. Congrats! This article reminded me that I've always wanted to get Pelican to work on my cluster but had no luck!
Here's my situation:
(1) My students and I use Octave a lot, so to be able to set up a cluster with MPITB would be great!
(2) We have password-less public-key authenticated ssh setup for a very simple cluster where we use bash scripts to scatter and gather fractal and povray renderings.
(3) Whenever we try PelicanHPC (or prior incarnations such as parallelKNOPPIX) we always had problems PXE booting the worker nodes after booting the liveCD on the master node. There must be a conflicting PXE server somewhere on our LAN, but the tech guy at my school swears up and down that he's isolated my classroom/lab. I'm not convinced of this, however, as I've had other conflicts when using other liveCDs (BCCD?) that use say DHCP to set up MPI.
Questions:
(1) Can I get PelicanHPC to work with passwrordles ssh as I already have this setup on 25 AMD Athlon 64bit dualcores?
(2) Can I setup a PelicanHPC cluster without using PXE, say by booting all nodes with the CD? As I understand it, MPI can be set to use ssh....
Thanx in advance,
