Method For Organizing Tasks In The Nodes Of A Computer Cluster, Associated Task Organizer And Cluster

A computer cluster comprising:

• several nodes,
• an organizer of tasks to be assigned to said nodes, configured, for at least some of said nodes, so as to:
• first, launch two containers on each of said nodes, a standard container and a priority container,
• next, for all or part of said nodes, with two containers, at each node,
• while a priority task does not occur, assign the resources of the node to the standard container thereof to execute a standard task, the priority container thereof not executing a task,
• when a priority task occurs, dynamically switch only a portion of resources from the standard container thereof to the priority container thereof, such that, on the one hand the priority task is executed in priority container with the switched portion of the resources, and on the other hand the standard task continues to be executed, without being halted, in standard container with the non-switched portion of the resources.
