[torqueusers] Runing multiple tasks on nodes

Dear all,


I am using both Torque and Maui on our Linux Cluster
I noticed that if I use the option

#PBS -l nodes=1:ppn=4:node1+1:ppn=4:node2


it does allocate 4 cpus on node 1
                       4 cpus on node 2

however if I use


#PBS -l nodes=node1:ppn=4+node2:ppn=4


it only allocates 1 cpu on node1 and 1 cpu on node2 

Any reason why ?
Do I need to set some parameters in the maui.cfg file ?
I tried to change some parameters but it did not help
Is the parameter TASKDISTRIBUTIONPOLICY of any use for that ?

Thanks for your help


Roberto
