Workers and Queues¶
The Workers and Queues page allows you to:
monitor resources (CPU and GPU, memory, video memory, and network usage) used by the experiments / Tasks which workers execute
view workers and the queues they listen to
create and rename queues; delete empty queues; monitor queue utilization; reorder, move, and remove experiments from queues.
To monitor resource utilization:
In the WORKERS tab, click a worker. The chart refreshes showing resource utilization for that worker. The worker info panel slides open, and the INFO tab appears showing information about the worker, its name, current experiment, current runtime, last iteration, and last update time.
Select a metric and time frame.
In the list of resources (top left side), select CPU and GPU Usage, Memory Usage, Video Memory Usage, or Network Usage.
In the period list (top right side), select 3 Hours, 6 Hours, 12 Hours, 1 Day, 1 Week, or 1 Month.
Optimize the use of your workers by monitoring worker utilization in the Workers tab.
To monitor worker utilization:
Open the Workers & Queues page, or switch from the Queues tab to Workers tab. The worker utilization chart appears. Hover over any data point and see average workers and total workers.
To monitor all queues:
Open the Workers & Queues page, or switch from the Workers tab to Queues tab. The queue utilization chart appears. The chart shows average wait time (seconds) and number of experiments queued for all queues.
Hover over any data point and see average wait time and number of experiments.
To monitor a queue:
View and manage a queue. In the queues list (lower right), click a queue. The chart refreshes showing metrics for the selected queue. The info panel slides open, and the EXPERIMENTS tab appears showing the enqueued experiments. You can manage the queue from the info panel EXPERIMENTS tab.
View information about the workers listening to the queue. In the info panel, click WORKERS.

Rename a queue - Click RENAME > Type a queue name > RENAME, or click DELETE.
Delete a queue - Click Delete.
Do any of the following by right clicking a queue in the queues list (lower right):
Reorder experiments in a queue - Drag an experiment to a new position in the queue, or click (menu) and then select Move to top or Move to bottom.
Move to a new queue - Click (menu) > Move to queue… > Select a queue > ENQUEUE.
Remove an experiment - Click (menu) > Move to queue… > Select a queue > ENQUEUE.
