Use the Computation tab to manage kernels, machines, and notebook runs from one place. This is an alternative option to performing the same operations using Kernel and Run under the main menu.
Use the Computation tab
Open the tab by clicking the Computation icon on the left-hand sidebar or selecting the Computation option from the command palette.
When opened, the tab looks as shown in the image below.
(Optional) Drag the items on the tab to re-arrange them.
The Computation tab provides the following options:
Runs the entire notebook.
Runs selected cells. To select several cells in the editor, press Esc, hold down Shift, and press Up or Down.
Clears outputs in all notebook cells.
Only on-demand machines
Activates selection of on-demand machines only for notebook computations. Recommended when you expect to have long computations and want to make sure they are not interrupted.
Changes the machine. Click the arrow next to the machine name and select an option from the menu. Confirm the machine change.
Starts or stops the machine.
Activates background computation and allows to choose a cut-off timer option.
Interrupts or restarts the kernel. The options are enabled only when there is a running computation.
Turns on the reactive mode.
Under Background computation:
Keeps background computation off.
Turn off after 30 min of inactivity
Enables background computation and sets the machine to shut down after the kernel is in idle state for 30 minutes.
Turn off after 2 hours of inactivity
Enables background computation and sets the machine to shut down after the kernel is in idle state for 2 hours.
Turn off after 24 hours of inactivity
Enables background computation and sets the machine to shut down after the kernel is in idle state for 24 hours.
Never turn off
Enable the mode without time restrictions. The machine keeps running even after the computation is finished or an error occurs.
Under Scheduled runs:
Scheduling is on/off
Turns on or off scheduled running for the notebook if there is a schedule created.
Click to edit the schedule for the notebook.
Opens the schedule dialog where you can schedule runs for the notebook. Find more details in Scheduling.
