[torqueusers] An issue when using pbs script to invoke different cpus from different nodes.

I use qsub to submit the job to my queue. Currently I've the following
lines in the pbs script invoked by qsub:
#PBS -l nodes=2:ppn=8
#PBS -l walltime=99:00:00
#PBS -j oe
#PBS -o out
#PBS -e err
#PBS -q default
As you can see, in the above example, the job will use 16 cpus equally
supplied by two nodes. But now, I want to let pbs assign the cpus and
nodes to this job according to the following requirements:
1- There are 8 cpus used for this job.
2- All of the these cpus may belong to one node, or can come from
different nodes, say, supplied by two/three/four nodes and so on.
Could you please give me some hints on this issue. Thanks in advance.
