Allocations and compute scheduling: Difference between revisions

The portal.alliancecan.ca/slurm site provides an intuitive interface for exploring job usage time series. The page contains a time series histogram figure window that displays usage metrics derived from job records on the Alliance national clusters. The initial metric displayed in the histogram is CPU-equivalent days for the logged-in user on the Cedar cluster. If the logged-in user does not have usage on the Cedar cluster the figure window will not have a histogram but rather contain the text “No Data or usage too small to have a meaningful plot”.The data summaries presented in the figure window can be modified by the edit and selection panels along the left margin of the page. The editing panels are "Select system and dates", "Parameters" and "SLURM account".

The "Select user’s account" pull down menu of the "SLURM account" panel allows the user to select the specific project account to be displayed in the figure window. If the “Select user’s account” is left empty the histogram figure window will display all of the usage for the logged in user across accounts on the specified cluster over the selected time period. The "Select user’s account" pull down menu is populated by a list of all the accounts that have job records on the selected cluster over the selected time interval. Once that a single project account is selected the usage histogram figure is updated and the summary panel titled "Allocation Information" is populated with relevant details of the project account. The height of each bar in the histogram figure corresponds to the metric for that day (e.g. CPU-equivalend days) across all users in the account on the system, where the top 8 users are displayed in a unique colour stacked on top of the summed metric for all other users in gray. The figure can be navigated using native Plotly tools (e.g. zoom, pan, etc) whose icons appear at the top-right when the mouse hovers over the figure window. The figure's right side legend can also be used to manipulate the figure display such that single clicking an item will toggle the item's presence in the figure, and double clicking the item will toggle isolating the figure to the single item.
