Slurm Dashboard

A dashboard for interacting with the Slurm workload manager in VSCode. It allows you to see running jobs, cancel jobs, submit new jobs, and more.

Features

There are two main views in this extension: Job Queue and Job Scripts. The first view is a list of all current user jobs in the queue. Actions are provided for canceling, resubmitting, and inspecting the jobs. The second view shows all detected job scripts and provides actions for inspecting and/or running them. These views are shown in the highlight below.

Requirements

This extension requires Slurm to be on the system where the workspace is located. Currently it only works with Slurm, but PBS, BSUB, and Flux support is planned.

Extension Settings

This extension contributes the following settings:

• slurm-dashboard.job-dashboard.showJobInfo: Show all job metadata in the job list. Default: false
• slurm-dashboard.job-dashboard.promptBeforeCancel: Prompt user before canceling a job. Default: true
• slurm-dashboard.job-dashboard.promptBeforeCancelAll: Prompt user before cancelling all jobs. Default: true
• slurm-dashboard.job-dashboard.refreshInterval: How many seconds between refreshes of the job queue view. Set to null to turn off auto-refresh. Default: 300
• slurm-dashboard.job-dashboard.extrapolationInterval: Extrapolate the job run times in the UI without querying the workload manager. Allows you to set a high job-dashboard.refreshInterval, but still see more realistic job run times. This has the danger of coming out of sync with the real times or not portraying job completion/failure, so it is turned off by default. Provide a number to specify the interval in seconds or null to disable extrapolation. Default: null
• slurm-dashboard.job-dashboard.persistJobs: Keep completed jobs in the job dashboard until they are removed with the X button. Default: false
• slurm-dashboard.job-dashboard.useNativeIcons: Instead of the job status icons shipped with the extension, use VSCode native codicons. Default: false
• slurm-dashboard.job-dashboard.sortBy: Sort the job list by this column. Set to null to leave the order returned by the workload manager. Choices: id, name, time left, status. Default: null
• [DEPRECATED] slurm-dashboard.submit-dashboard.jobScriptExtensions: Use jobScriptPatterns setting instead. File extensions used to identify job scripts. Default: [".sbatch", ".slurm", ".job"]
• slurm-dashboard.submit-dashboard.jobScriptPatterns: Glob patterns to identify job scripts. Default: ["**/*.slurm", "**/*.sbatch", "**/*.job"]
• slurm-dashboard.submit-dashboard.promptBeforeSubmitAll: Prompt user before submitting all job scripts. Default: true
• slurm-dashboard.submit-dashboard.sortBy: Sort the job script list by this column. Set to null to leave the order the glob pattern discovered the files. Choices: filename, rel path, last modified, newest, oldest. Default: last modified
• slurm-dashboard.setJobWorkingDirectoryToScriptDirectory: Launch job scripts with the working directory as the location of the job script. Default: true
• slurm-dashboard.backend: Scheduler backend. Choices: slurm, debug. Default: slurm
• slurm-dashboard.slurm-backend.squeueUserArg: By default --me is passed to squeue to get the users jobs. Slurm versions older than 20.02 do not support --me. This settings provides a way to fallback to the --user flag instead. Choices: me, user. Default: me

Most notable is the job-dashboard.refreshInterval setting. The job queue view refreshes its data at regular intervals. To avoid overloading the login nodes or the workload manager the refresh interval is set to a high value. By default it is 300 seconds. This can be changed to the users preference or auto-refresh can be turned off entirely by setting it to null.

If you still want to see live job times, you can set job-dashboard.extrapolationInterval, which will extrapolate the current job time based on the last available value from the workload manager. This will make the UI more informative, but has the danger of coming out of sync with the real job times and/or not capturing job completion and failure. However, these will be corrected the next time the jobs are refreshed from the queue. Due to these reasons extrapolation is turned off by default. An example of what this looks like when enabled is shown below.

0.0.13

• use glob patterns to find job scripts instead of extensions. The glob patterns can be specified with slurm-dashboard.submit-dashboard.jobScriptPatterns. The old setting, slurm-dashboard.submit-dashboard.jobScriptExtensions, is now deprecated and will be removed in a future version.
• collect node list data and display it in the job info display
