Introduction

The command qhost shows the current status of the available SGE hosts, queues and the jobs associated with the queues. Selection options allow you to get information about specific hosts, queues, jobs or users. If multiple selections are done a host is only displayed if all selection criteria for a host are met. Without any options qhost  will display a list of all hosts without queue or job information. With option -j  display jobs hosted by host(s)

qhost -j -h node16                       shown which jobs are running on the host or a set of hosts. 
qhost -h node23,node24                   show host info for multiple nodes
qhost -q -h node23,node24                host info plus queue info

It has the following syntax:

qhost [ -cb ] [ -F [resource_name,...] ] [ -help ] [ -h host_list ] [ -j ] [ -l resource=val,... ] [ -u user,... ] [ -xml ].

options

 [-cb]                      show topology based information (socket/core)
  [-F [resource_attribute]]  show (selected) resources
  [-h hostlist]              display only selected hosts
  [-help]                    print this help
  [-j]                       display jobs hosted by host
  [-l attr=val,...]          request the given resources
  [-q]                       display queues hosted by host
  [-u user[,user,...]]       show only jobs for user
  [-xml]                     display the information in XML-Format
