At the moment when a job gets allocated to a node (regardless of cpusets) the
node shows a <#>/<jobid> which queried (e.g. pbsnodes <node>). 

What I would like to propose is that in the case of cpusets that the <#> is
actually the same as the core that was allocated for the cpuset. This would
make tracking jobs easier as we could tell which cpus a job was allocated
without having to search through on the node.

I do see a few issues. Like what happens for people not using cpusets. What
happens for clusters where there are more jobs allocated than there are cpus.
But I think in both those cpusets are not active.

Cheers,
Craig.
