3.3 Job Details–Functional Areas

The Job Details page shows additional information about a job and lets you make certain modifications to a given job. To access this page, from the Workload view, click on the Job ID link for the job.

This topic describes functional areas, including field descriptions, available on the Job Details page. To expand and display a functional area, click to the left of the title of the desired area.

The information contained in, and the actions you can perform using, the Job Details page will vary based on the job's status, the user's role permissions and/or the fields available from the application template.

In this topic:

3.3.1 Priority

The Priority area requires the "Job Details - Priority Analysis" permission. See 1.7 Role Permissions for more information about the available permissions you can set.

The Priority area lists the priority factors applied to the job for scheduling purposes. Expand the area to view the prioritization factors.

Expand the Priority area to view the additional information. Click to refresh the priority information.

The Priority area is organized as follows:

The top area shows the cumulative value for these prioritization areas:

  • User Job Priority – User defined priority factors. See Job Priority Factors in the Moab Workload Manager Reference Guide for more information on the available factors.

    This feature requires the User Priority field to be enabled in the application template and the Moab ENABLENEGJOBPRIORITY server parameter must be set to "TRUE". See 4.4.3.C Advanced Settings for more information on the User Priority field.

  • System Priority – Factors that are used to override Moab Workload Manager's start priority to allow jobs to start sooner than they would ordinarily. See mjobctl in the Moab Workload Manager Reference Guide for more information on the available factors.
  • Start Priority –Moab's defined start priority.
  • Job Start Count – Number of times Moab has requeued the job after a job failure or preemption.

The second area provides details about how Moab calculated the start priority. The different start priority groups are listed and are also broken down into each factor within the group. The cumulative weight for the group and the how that breaks down into the different factors are provided.

3.3.2 Job Messages

The Job Message area lists any messages reported by Moab. These are the same messages you can view in Moab using checkjob -v -v.

Expand the Job Messages area to view the reported messages, if any. Click to refresh the job message information.

Credentials Area

The Credentials area displays information about the user who created/submitted the job.

The following table describes the fields in the Credentials area.

Field Description
User The user that submitted a job.
Group Displays the group credential, which represents an aggregation of users. User-to-group mappings are often specified by the operating system or resource manager and typically map to a user's UNIX group ID. However, user-to-group mappings may also be provided by a security and identity management service, or you can specify such directly within Moab.
Account Displays the account credential. This credential is generally associated with a group of users along the lines of a particular project for accounting and billing purposes.
Class Displays the job class. The concept of the class credential is derived from the resource manager class or queue object. Classes differ from other credentials in that they more directly impact job attributes. In standard HPC usage, a user submits a job to a class and this class imposes a number of factors on the job. The attributes of a class may be specified within the resource manager or directly within Moab.
Quality of Service Quality of service status applied to the job (for example, low, medium, or high).

CPU Statistics Area

The CPU Statics area contains a graph depicting the CPU statistics of the job. Click to open a pop-window to specify the range and refresh intervals for the displayed statistics. You can also manually update the display.

3.3.4 Time Frame

The Time Frame area provides information on the job's start and completion times as well as duration information.

The following image is an example of the Time Frame area.

The following table describes the fields in the Time Frame area.

Field Description
Start Time The date and time that the job started.
Duration

The amount of time requested for the job in seconds. This represents the maximum amount of time the job is expected to run and is specified when the job is submitted. This does not represent the amount of time the job actually ran if the job is completed.

Jobs that exceed their wallclock limits are subject to the corrective action specified in the Moab WCVIOLATIONACTION parameter.
Completion Time The date and time that the job completed; "None" if the job is running or idle.
Actual Duration The amount of time the job has been running (or ran if the job is completed).
