Monitoring Usage

There are two general methods to monitor the usage of time for a project:

1.  Monitor through https://monitoring.sdcc.bnl.gov/pub/allocation/.  This is a web portal that shows usage for USQCD sub accounts on the 3 clusters.

Usage for the IC and Skylake clusters is under the Annie-IC option in the upper-left.  For the 2018-2019 allocation year, all USQCD projects are listed under the sub-option lccd-18-19.  The units for the allocations are nodes * minutes * 36 (the 36 is the number of CPU cores per node).  USQCD allocates in Jpsi core-hours, which can be converted to node-hours on the IC or Skylake, using the conversions in the USQCD call for propsals.

Usage on the KNL is shown under the Frances-KNL option.  For the 2018-2019 allocation year, all USQCD projects are listed under the lqcd-knl sub-option.  

The units for the allocations are nodes * minutes * 256 (the 256 is the number of cores per node (64) times the number of hyperthreads (4)).

2.  The SLURM terminal command sshare and sreport can be used to generate finer grained reports about the usage.  For example. to see a breakdown of the usage under the axialgpu-18-19 account from October 1, 2018 through November 15, 2018, this command:

/usr/bin/sreport cluster AccountUtilizationByUser account=axialgpu-18-19  start=2018-10-01-00:00 end=2018-11-15-23:59 format=Accounts,Login,Used
