Job history & analytics

Press H from the main screen to open the history screen — a durable record of every job slurmhub has observed, backed by a local SQLite database (see Database configuration). Unlike the live job table, history survives restarts and keeps jobs long after they leave the queue.

The screen has two modes, toggled with a:

Past runs

A scrollable, filterable table of recorded runs. Each row shows the favourite star, the profile/cluster it ran on, the job ID and name, final state, submit time, elapsed time, and the CPU / GPU / memory it reserved, plus any favourite note.

Filter and search to find a run:

Key	Action
1 / 2 / 3 / 4	Filter RUNNING / PENDING / COMPLETED / FAILED.
0	Clear the state filter.
t	Cycle the date range: all time → last 24h → 7 days → 30 days.
p	Toggle scope between the current profile and all profiles.
F	Show favourites only.
/	Search by job name or ID.
Enter	Open the selected run’s detail screen.

Usage aggregates

Press a to switch to the analytics view, which sums what you consumed from the cluster over the selected date range:

• GPU-hours, CPU-hours, and memory (GB·h) — allocated resources × elapsed time, summed across the matching runs.

• Average GPU utilisation — measured from periodic nvidia-smi samples (only when utilisation capture is enabled; see below).

• A per-profile breakdown when scope is set to all profiles.

Note

Aggregates are computed from each run’s final allocation × elapsed time, so they are independent of how many snapshots were recorded — re-opening the app does not double-count. CPU-hours and memory figures depend on the extra squeue/sacct fields slurmhub now captures (allocated CPUs and requested memory).

Favourites & notes

Mark runs you want to keep or revisit. Favourites are never removed by the retention policy, and you can attach a short note (e.g. “best hyperparams”).

• From the history screen: f toggles the favourite on the highlighted row, n edits its note.

• From the job detail screen: f and n do the same for the job you are viewing, and the star + note are shown at the top of the screen.

Favourites are not shown as a column in the live job table — they live in the history and detail views.
