Is it possible to submit a job to one of the nodes from a list of nodes?

Please follow the below instructions , this might satisfy your requirement

  1. Define the custom resource:

    qmgr –c "c r my_node_type type=string_array,flag=h"

  2. Append the custom resource to resources: line in sched_config file:
    resources: “ncpus, mem, arch, host, vnode, aoe, my_node_type”
    Note: after updating sched_config file, it is necessary to kill -HUP the pid of pbs scheduler.

  3. Set each queue’s default_chunk for the new resource to the value you are using
    to associate it with vnodes or compute nodes using qmgr:

    qmgr –c "s q redq default_chunk.my_node_type = red"
qmgr –c "s q blueq default_chunk.my_node_type = blue"
qmgr –c "s q greenq default_chunk.my_node_type = green"
qmgr –c "s q pinkq default_chunk.my_node_type = pink"

  4. Set the value for the new resource at each vnode:

    qmgr –c "s n node01 resources_available.my_node_type = red"
qmgr –c "s n node02 resources_available.my_node_type = blue"
qmgr –c "s n node03 resources_available.my_node_type = green"
qmgr –c "s n node04 resources_available.my_node_type = pink"

Note:

To submit jobs, so that jobs land only on node1:

  qsub -q redq -- /bin/sleep 100   # This job is scheduled on node01

To use cross utilization of nodes, append my_node_type to nodes (here we are using node01 / node02 as example)

  qmgr –c "s n node01 resources_available.my_node_type += blue"
  qmgr –c "s n node02 resources_available.my_node_type += red"

Now,

  qsub -q blueq -- /bin/sleep 100 # has two nodes node01 and node02 
  qsub -q redq  -- /bin/sleep 100 # has two nodes node01 and node02

I hope this helps
