Well, actually I did:Jose,pbs thinks each of your machines has only one cpu. Please execute for each node: qmgr -c "s n neurona1.brain np=2"
qmgr -c "s n neurona1.brain np=8"
because there 8 client nodes and I'd like to have at least 8 parallel processes running in the cluster.
All right! It's now working properly.
Anyway, this solution doesn't scale up easily. I mean, I would have to change the definitions for every node everytime a new node is added/deleted. Maui/PBS still allocate all of the nodes to every new job submitted:

Is there anyway to make them allocate only one processor for each new process?
I've read something related to this on the qsub man page (option -l resource_list). But I don't know to config the system to get it done. Just for your reference, the jobs I'm submitting are scripts like this (b.sh):
----
#!/bin/tcsh
#PBS -N BA3
#PBS -o salida3txt
#PBS -e errores3.txt
#PBS -q workq
set program = ~/jl/ba/ba
set prefix = ~/jl
set seed1 = 12264671;
set iter = 6000;
$program $prefix/datos_sc/iono.tra $prefix/datos_sc/iono.tst $iter $seed1
----
And I submit them with a single: "qsub b.sh"
