when i submit serial job to the cluster by torque+maui,the job always run
at the same node untill all the cpus of that node is used .
for example ,I use "lx" account to submit serial job "dfdf", every nodes
have two cpus.and now every cpu is free,no job is running.

as you see,the first two jobs are running at the same node.this is not load
balance.i want the job 102 run at the other node not the node c1501.after
all the cpus of the node c1501 is used,the job 103 is starting to run at
the other node c1503.
i have configured the torque server by using "node_pack=false",but it not
works.
and i also configure the maui.cfg file ,adding "NODEALLOCATIONPOLICY
MAXBALANCE
NODEACCESSPOLICY SINGLEUSER",but it still not works.
i am very disappointed,how can i do .
this is my server's configuration.
