Hi All,
I am wondering whether it is better to have extra applications/software
such as Portland Group compilers and their associated recompiled mpich
libraries installed locally on each node of the cluster or only on the
master and then mounted across the client nodes. I'm thinking that I'd
rather have it local on each system so we don't have performance
problems but then again I don't want to have to install on each node
every time we make a change in version. How are you guys handling this
and do you have any suggestions on how I might be able to make the
process of updating client nodes should I decide to install locally?
Thank you,
Jenny =)
I have a group that is using Portland Group compilers because they need
f90 and so it looks like we have to recompile mpich so that the
libraries will be compatible with the compiler. This brought up the
question of whether we should install mpich locally on each system or in
/usr/local and mount that across all nodes. We also found that the
libraries from the Portland Group compilers directory needs to be
accessible to the comp nodes as well.
