Jobs I add to the queue stays there in "Queued" state without attempts to be executed (unless I manually qrun them)

/var/spool/torque/server_logs say just

04/11/2011 12:43:27;0100;PBS_Server;Job;16.localhost;enqueuing into batch, state 1 hop 1
04/11/2011 12:43:27;0008;PBS_Server;Job;16.localhost;Job Queued at request of test@localhost, owner = test@localhost, job name = Qqq, queue = batch

The job requires just 1 CPU on 1 node.

# qmgr -c "list queue batch"
Queue batch
    queue_type = Execution
    total_jobs = 0
    state_count = Transit:0 Queued:0 Held:0 Waiting:0 Running:0 Exiting:0 
    max_running = 3
    acl_host_enable = True
    acl_hosts = localhost
    resources_min.ncpus = 1
    resources_min.nodect = 1
    resources_default.ncpus = 1
    resources_default.nodes = 1
    resources_default.walltime = 00:00:10
    mtime = Mon Apr 11 12:07:10 2011
    resources_assigned.ncpus = 0
    resources_assigned.nodect = 0
    kill_delay = 3
    enabled = True
    started = True

I can't set resources_assigned to nonzero because of Cannot set attribute, read only or insufficient permission resources_assigned.ncpus.

When I qrun some task, this goes to mom's log:

How to make it execute jobs automatically, without manual qrun?

Vi.

I spent several hours on the problem with similar symptoms and at the end it was single option missing in server settings:

qmgr -c "set server scheduling = True"

Normally it would be the scheduler that decides when jobs are to be run, i.e. when there are sufficient resources, and tells the server to run the job. Are you running a scheduler? TORQUE includes a basic scheduler (pbs_sched), or you could install and run the more sophisticated maui (free) or moab (pay-for).

The pbs_server part of PBS/TORQUE is a "resource manager" - essentially just a 'framework'. It makes no decisions itself: that is the job of the scheduler.
