Q: How many AUs has my job used?
A: You can obtain an estimate of the number of AUs an HPCx job has used
by calling the accounting script at the end of your job.
For example, the script can be called by adding the following to the
end of your batch script:
/usr/local/packages/bin/accounting_g128 [cpus] [tasks_per_node]
where cpus is the number of cpus you have requested and
tasks_per_node is the number of processors you wish to use
within a 16-way node. If you have not specified the number of
processors per 16-way node earlier in your batch script, you should set
this value to 16.
So, for example, to determine the number of AUs you have used for a
128 processor job, you would specify:
/usr/local/packages/bin/accounting_g128 128 16
This will return an estimate of the number of AUs you have used. Note
that the number of AUs is calculated from the job start time to the time
this script is called. Hence by calling this script at the end of your
job you will gain a good estimate of the number of AUs used. There is
however a small shut down time, which will not be included in these
estimates.
