Hello there



I have a cluster of 44 nodes wn0[01-44].



I use the following script mypbs.pbs to submit jobs



_____

#PBS -N simpledemo

#PBS -l nodes=7

#PBS -q tuc

#PBS -m abe -M ***@isc.tuc.gr

#PBS -k oe



myjob

_____



Instead of binding 7 nodes it binds node wn007. The same if I try to bind 1
or 2 or 3 or 4 or ...23.. or 44 nodes, always binds the N-th node where N
between 1 and 44.



Instead of

#PBS -l nodes=7

I try

#PBS -l
nodes=wn002.grid.tuc.gr:ppn=2+wn038.grid.tuc.gr:ppn=2+wn017.grid.tuc.gr:ppn=
2+wn020.grid.tuc.gr:ppn=2



It binds always only the first node of the list whatever it is.



pbsnodes command return all nodes running and free...



Any hint

It's probably defaulting to ppn=1 and giving you 7 cores on the
one node. Try the following where "X" equals the number of cores
on each node.

#PBS -l nodes=7:ppn=X
