Throughput

Introduction

This plugin analyzes the frequency at which jobs are submitted and enqueued by the job scheduler, as well as their slowdown (time spent by a job on the cluster over its execution time).

Key metrics

  • Number of jobs arriving per second, minute, hour, day or month

  • Inter-arrival (time between submission of 2 consecutive jobs)

  • Job submission time

  • Job submission weekday

  • Cumulative job load (queued and running)

  • Slowdown. This metric allows you to put into perspective the time jobs spend in queue vs. their execution time.

The Cumulative Distribution Function in this example shows that 96.48% of jobs had a slowdown <= 2 meaning that they wait at most as long as their execution time before they could start.
