This is set via the configuration for each queue. So for example for the all.q:
$ qconf -sq all.q
You will see a line like this:
slots 1,[murdoch.lclust=8],[ben.lclust=4],[bill.lclust=4], \
[donald.lclust=4]
This means that the default for new hosts is 1 slot and for the named
hosts, the numbers as set individually. (murdoch has 8 for example).
You can then change this like this:
$ qconf -mq all.q

I'm with Evi, NFS on a local gigabit subnet running jumbo frames with
a switch that can handle such things. I like the HP 2824 for this bit
it is a bit overkill when you can get something like a Linksys SR2024
for (usually) less than half the price.
Also when I say NFS, I really mean AutoFS as it is far more fault tolerant.
I have often thought about writing a quick "howto" for SGE + NFS + FSL
+ Ubuntu/Linux in general but in past there was not much feedback
regarding a need for this.
If others are interested I can post some example configs and others
can comment and/or add to it.
