Abstract: A method, apparatus, device and medium for executing tasks in a computing system are provided in the present disclosure. The computing system comprises a first computing node and a plurality of second computing nodes, available duration of the first computing node is known, and the available duration of the plurality of second computing nodes is unknown. A task manager is started at the first computing node, the task manager being used to manage a plurality of tasks to be executed in the computing system. The task manager requests a set of second computing nodes in the plurality of second computing nodes to the computing system. The task manager distributes a target task in the plurality of tasks to the set of second computing nodes so as to execute the target task by using the set of second computing nodes.

Abstract: Disclosed is a folding device, comprising: a first folding part, configured to fold, for a first time in a first direction, a folded object in half; a second folding part, configured to fold for a second time in a second direction in half, the folded object that has been folded in half for the first time, wherein the first direction is opposite to the second direction; a third folding part, configured to fold, for a third time in a third direction, one end of the folded object that has been folded in half for the second time, wherein the third direction is perpendicular to the second direction; a fourth folding part, configured to fold, for a fourth time in a fourth direction, the other end of the folded object that has been folded in half for the second time, where the fourth direction is opposite to the third direction.
