Would it be possible for qhost -xml output to include the number of slots used

Okay, I see how it is done - there are multiple job entries for each
slot.
Indeed, like the non-XML version. The SGE support
in<https://oss.trac.surfsara.nl/jobmonarch> should provide an example of
similar processing from qstat output.
Job 31911 is a 4 slot pe job - why are there 5 entries (one of which
is a "MASTER")?
Because the PE has job_is_first_task false?
It is, but something doesn't jive:
job_is_first_task
The job_is_first_task parameter can be set to TRUE or FALSE. A value
of TRUE indicates
that the Sun Grid Engine job script already contains one of the tasks
of the parallel
application (the number of slots reserved for the job is the number of
slots requested
with the -pe switch), while a value of FALSE indicates that the job
script (and its
child processes) is not part of the parallel program (the number of
slots reserved for
the job is the number of slots requested with the -pe switch + 1).
My -pe mpi 4 job:
qstat:

Everything except for qhost refers to 4 slots being used and I can fit 4 cpu
jobs onto my 4 slot hosts.
