[torqueusers] Help with Time-Share

I'm very new to this torque thing, but here's what I want to do:
I have a program that will be submitting many jobs, I would like each
job to run on one machine (and only have one job running on each
machine at once) and keep the rest queued.
I think to do this I need to setup a timesharing system.
I've added :ts to my server_priv/nodes file for each node in my
system. I've also added:
load_balancing: true ALL
to my sched_config file.
When I try to submit a job with qsub -I , these two messages show up
in my log file:
08/11/2005 13:30:13;0008; pbs_sched;Job;72835.os-12;Job Deleted
because it would never run
08/11/2005 13:30:13;0040; pbs_sched;Job;72835.os-12;Not enough of the
right type of nodes available
If I remove the :ts from my nodes file, then the job is always sent to
the default node. However, under that scheme when I submit a large
number of jobs quickly that machine is overloaded and jobs don't seem
to ever be sent to any other nodes.
Here is my queue setup.
Qmgr: print server
# Create queues and set their attributes.
# Create and define queue batch
create queue batch
set queue batch queue_type = Execution
set queue batch resources_default.nodes = 1
set queue batch resources_default.walltime = 01:00:00
set queue batch enabled = True
set queue batch started = True
# Set server attributes.
set server scheduling = True
set server default_queue = batch
set server log_events = 511
set server mail_from = adm
set server scheduler_iteration = 600
set server node_ping_rate = 300
set server node_check_rate = 150
set server tcp_timeout = 6
set server job_stat_rate = 30
pbsnodes show's all the nodes at ntype=time-shared
Is timesharring even what I want here? I think that it is, but I
could be wrong. What more do I need to do to get timesharring to
Thanks for your help!
