Background computation
Last modified: 28 November 2023
Background computation mode in Datalore allows you to run computations even if the browser tab is closed. This is particularly important when you expect long cell execution.
Keep in mind that work with background computation on can significantly increase your resource consumption. Therefore, by default, this mode is disabled.
note
Important
With background computation off, the computation is stopped as soon as both the browser is closed and the kernel becomes inactive. If there is some code being executed, closing the browser will not stop the computation.
You can select one of the following options when enabling background computation:
Turn off after 30 min of inactivity to enable background computation and set the machine to shut down after the kernel is in idle state for 30 minutes.
Turn off after 2 hours of inactivity to enable background computation and set the machine to shut down after the kernel is in idle state for 2 hours.
Turn off after 24 hours of inactivity to enable background computation and set the machine to shut down after the kernel is in idle state for 24 hours.
Never turn off to enable the mode without time restrictions. The machine keeps running even after the computation is finished or an error occurs.
