I am trying to submit a parallel job using torque and maui. qstat says
that the requested number of cpu are allocated. But when I look at the output
from my program, I see that only one cpu is being used.

Here is some information
which may be usefull.

The parallel program is compiled with openmpi 1.1.4

torque 1.1.8
maui 3.2.6

[praveen at master torque]$ qmgr
Max open servers:
Qmgr: print server
# Create queues and set their attributes.

# Create and define queue default
create queue default
set queue default
queue_type = Execution
set queue default enabled = True
set queue default
started = True
# Set server attributes.
set server scheduling = True

set server acl_host_enable = False
set server managers = maui at master.tifrbng.res.in

set server managers += root at master.tifrbng.res.in
set server default_queue
= default
set server log_events = 511
set server mail_from = adm
set server
query_other_jobs = True
set server scheduler_iteration = 600
set server
node_check_rate = 150
set server tcp_timeout = 6
set server pbs_version
= 2.1.8

Any help is greatly appreciated.
