Method, apparatus, device and medium for performing task in computing system

An electronic device, comprising:

• at least one processing unit;
• and
• at least one memory coupled to the at least one processing unit and storing instructions to be executed by the at least one processing unit, the instructions, when executed by the at least one processing unit, causing the electronic device to perform a method of executing tasks in a computing system, the computing system comprising a first computing node and a plurality of second computing nodes, available duration of the first computing node being known, available duration of the plurality of second computing nodes being unknown, and the method comprising:
• starting a task manager at the first computing node, the task manager being used to manage a plurality of tasks to be executed in the computing system;
• requesting, by the task manager, a set of second computing nodes in the plurality of second computing nodes to the computing system;
• and
• distributing, by the task manager, 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.

A non-transitory computer-readable storage medium, on which a computer program is stored, the computer program, when executed by a processor, causing the processor to perform a method of executing tasks in a computing system, the computing system comprising a first computing node and a plurality of second computing nodes, available duration of the first computing node being known, available duration of the plurality of second computing nodes being unknown, and the method comprising:

• starting a task manager at the first computing node, the task manager being used to manage a plurality of tasks to be executed in the computing system;
• requesting, by the task manager, a set of second computing nodes in the plurality of second computing nodes to the computing system;
• and
• distributing, by the task manager, 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.
