What command do you use to get the number of GPUs available on a particular queue?

Suppose you have some nodes "n1", "n2", and "n3" associated with a particular queue named "gpu".  Each node has 4 GPUs.  What command do I use to query the queue to find out how many total GPUs are available on that queue, which, in this example, will be 12 GPUs, since there are 3 nodes associated with the queue and each node has 4 GPUs?

For example, I am setting the number of GPUs available on each node using the following commands.

qmgr -c 'set node n1 resources_available.ngpus=4'
qmgr -c 'set node n2 resources_available.ngpus=4'
qmgr -c 'set node n3 resources_available.ngpus=4'

 

I am associating nodes "n1", "n2", and "n3" with queue "gpu" using the following commands. 

</code><code class="java plain">qmgr -c&nbsp;<code class="java string">'create resource Qlist type=string_array, flag=h'<br /><br />grep Qlist /var/spool/pbs/sched_priv/sched_config<br />resources:&nbsp;"ngpus, ncpus, mem, arch, host, vnode, aoe, eoe, Qlist"

<code class="java string">qmgr -c&nbsp;'set queue gpu default_chunk.Qlist = gpuQ'

qmgr -c&nbsp;"set node&nbsp;n1 resources_available.Qlist='gpuQ'"<br /><code class="java plain">qmgr -c&nbsp;"set node n2 resources_available.Qlist='gpuQ'"
<code class="java plain">qmgr -c&nbsp;"set node n3 resources_available.Qlist='gpuQ'"

<br />What command do I use to report that queue "gpu" has 12 GPUs that are available, and also, if some of those GPUs become in use, what command do I use to show that "N" out of 12 GPUs are in use?
