How do I output nodes in a certain queue to std out?

It’s pretty simple, but I can’t seem to find a way to output a list of nodes to std out based off of the queue.

Thanks! Sorry if this is obvious, I couldn’t figure it out with qstat, qmgr or pbsnodes.

Good question @dward4 indeed :+1:

There is no command to get this output. You would need to write a script ( bash, python , perl or others ) to get this .

Might help:

import os
import sys
queue_cmd="source /etc/pbs.conf; $PBS_EXEC/bin/qmgr -c 'l q @default' | grep ^[a-zA-Z]  | awk '{print $2}'"
for queuename in os.popen(queue_cmd).readlines():
    queuename=queuename.strip()
    qstat_rn1_cmd = "source /etc/pbs.conf ; $PBS_EXEC/bin/qstat -rn1 | tail -n +6  | grep " + queuename + " | awk \'{print $12}\' > "+ queuename +".txt"
    os.system(qstat_rn1_cmd)
def nodes_return(queuename):
    nodelist=[]
    filename="./"+queuename+".txt"
    nodes=open(filename,'r').readlines()
    for line in nodes:
        line=line.strip()
        line=line.split('+')
        for node in line:
            node=node.split('/')[0]
            nodelist.append(node)
    nodelist=list(set(nodelist))
    return nodelist
for i in os.popen(queue_cmd).readlines():
    i = i.strip()
    j=nodes_return(i)
    print i,"(",len(j),")"
    print ','.join(j)

Thanks @adarsh!

This worked for me (similar to what you have in queue_cmd, line 3:

qmgr -c ‘p n @default’ | grep “queue = <queue_name>” | awk ‘{print $3}’
