Hello, We have a 64 home-made diskless cluster and 36 nodes diskless cluster (running thin-oscar) The next 200 nodes will arrive soon and be up by the end of december. Our experience with diskless nodes is that you need a server for 64 nodes, especially at boot time (well, we were not using tftp-ha and this limit is maybe higher than that) or if your users uses a lot of NFS (ie file I/O) and parrallel computation (MPI, PVM) at the same time on the same network.
The thin-OSCAR workgroup (thin-oscar.sf.net) has been started to address the specific issue of supporting diskless/systemless compute nodes within OSCAR. I'm currently packaging it for OSCAR. Should be ready within a week and/or for SC2002. Ben The config file is there (you need to compile a new kernel at this time) http://mike.si.usherb.ca/~mike/oscar/ramdisk.cfg The oscar2thin is there (shell script) http://mike.si.usherb.ca/~mike/oscar/oscar2thin Then you do a (*oscarimage= name of the image you build with SIS/OSCAR*) ./oscar2thin 80 /var/lib/systemimager/images/oscarimage thinimage.img and it will make a lot of the necessary changes. Some are manual and explained once the script is over. Do not use it the first time on a production cluster ;-)) If you can wait, the OSCAR package will be more human-friendly and all will be automated...
