Hi Trevor, I got a simple solution for that: I got all the software (OS, bootloader and programs) installed in one folder on the headnode and I am simply using rsync to copy it over to the nodes. So apart from the home directory, there is only /opt and the SGE NFS mounted.
I am not running NIS or suchlike but stick to the old password, shadow, and group files in /etc. This way around if the headnode crashes there is a good chance the program will continue to run until the headnode is back. From experiences that is working (strangely but true). Also, as I got a heterogeneous environment in one cluster, i.e. Sandybridge, Ivy-Bridge and Haswell CPUs, I can distribute the highly optimised libraries/programs individually. This is a bit of manual work but given I don't need to re-install the nodes often the installation of the users and the programs are actually easy. I know there are other ways of doing it and I think they all have their pros and cons. In the end, use something you feel comfortable with and you know how to manage. My 2 cents here :D All the best from a dark London Jörg On Dienstag 26 Mai 2015 Trevor Gale wrote: > Hello all, > > I was wondering what solutions other use for easy software installation > across clusters.
