Job List With Compare Switch

Job list with compare switch. In this example, filters return 145 jobs, while no job is selected manually.

Accessible from the job list primary view, the job compare view allows for the comparison of metric statistics in a pseudo-time-dependent manner.

The “Compare Jobs” button is located in the upper right corner of the job list view. Jobs for comparison are either selected by

  1. … a combination of filters resulting in a dataset of 500 jobs or less.
  2. … manual job selection by checking the box in the job info card.

If too many jobs are returned by the current filter selection, the button will be disabled.

If jobs are directly selected from the current job list, the button will display the current count, as well as an additional “Reset” button, which will empty the list of selected jobs, if pressed.

Manual job selection will also work if the current job list has more than 500 returned jobs, while the subsequent job compare view will ignore all additional filters, and only show selected jobs. Returning to the job list also returns with the last used filters.

Job Compare Options and Resource Compare

Job compare view top elements. The count of 145 jobs remains after switching to this view. The resource plot shows jobs sorted by their startTime, and all jobs have allocated accelerators (red data line).

The compare view features a reduced header:

  • Sorting is disabled, as jobs are always sorted by startTime in ascending order.
  • The filter component is removed and only shows the total number of compared jobs.
  • The refresh component is also removed.

The “Metric Selection” is active and can be used to add additional metric comparison plots to the view, if desired.

“Return to List” closes the compare view and restores the former job list view.

The “Resource Compare” plot is always shown at the first position. It features a semi-logarithmic view of allocated job resources in a pseudeo-time-dependent manner, as all jobs are sorted by actual start time. The data is colored as follows:

  • Black: Nodes - will always be at least 1 (Note: Also for shared jobs!)
  • Blue: Hardware Threads ( ~ Cores)
  • Red: Accelerators - Can be zero! If so, no line is rendered.

The legend includes further information, such as:

  • Job-ID
  • Cluster (and subCluster) on which the job ran
  • Runtimeof the job

Job Compare Metric Plot and Table

Job compare view metric plot and table. ‘Clock’ metric statistics are plotted for every job sorted by their startTime. All information is also shown as sortable table at the bottom of the compare view.

Below the resource compare plot, the individual metric compare plots are rendered. For each job, the Min/Max/Avg of the respective metric is plotted in a banded manner.

Zooming is possible, and will be synchronized to all other rendered plots, including the resource comparison.

Below the plots, all information is again rendered as a single table consisting of the following columns:

  • JobID
  • Start Time
  • Duration
  • Cluster
  • Resources (Nodes, Threads , Accs)
  • For each Metric: Minimum, Maximum, Average

It is possible to filter for specific jobIDs or parts thereof, all other columns are sortable.

Clicking on a JobID will lead to the respective Job View.
