[torqueusers] Maui ignores resource -l proc

I am pretty new to torque and maui, so I hope this is not a dumb question:
We are running a cluster with arounf 60 nodes and 400 cores . I have set up
torque-3.0.2 with maui-3.3.1 for a cluster with 3 queues.
Some users would like to specify the number of cores with the -l procs=
directive, since they do not care how many cores they get on the individual
nodes. When such a job with a specification of -l procs is submitted, I
observe the following behaviour with maui, e.g.:
qsub -I -l procs=32
output from tracejob -v
Allocated are 2 nodes with 8 cores each = 16 procs
where the number for Resource_List.neednodes=2:ppn=8 is taken from
which I have defined in the torque queue. When I change that value for
resources_default.nodes maui just uses that value for the node and core
allocation, so it seems that -l procs is completely ignored and instead maui
uses the default resources defined for the queue.
If I am using pbs_sched instead of maui there is no such problem and the
correct number of cores are allocated to the job when specifying -l procs=32.
The maui config file is just the standard file coming from the distribution
with very little changes such as:
I am grateful for any help...
