Computation tab

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

  1. 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.

    • Under Cells:

      Option

      Description

      Run all

      Runs the entire notebook.

      Run selected

      Runs selected cells. To select several cells in the editor, press Esc, hold down Shift, and press Up or Down.

      Clear outputs

      Clears outputs in all notebook cells.

    • Under Machine:

      Option

      Description

      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.

      Machine selection

      Changes the machine. Click the arrow next to the machine name and select an option from the menu. Confirm the machine change.

      Machine start/stop

      Starts or stops the machine.

      Background computation

      Activates background computation and allows to choose a cut-off timer option.

    • Under Kernel:

      Option

      Description

      Interrupt/Restart

      Interrupts or restarts the kernel. The options are enabled only when there is a running computation.

      Reactive mode

      Turns on the reactive mode.

    • Under Background computation:

      Option

      Description

      Disabled

      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:

      Option

      Description

      Scheduling is on/off

      Turns on or off scheduled running for the notebook if there is a schedule created.

      Scheduled settings

      Click to edit the schedule for the notebook.

      Create schedule

      Opens the schedule dialog where you can schedule runs for the notebook. Find more details in Scheduling.
