Abstract:
1. A method of managing preemption of a parallel application, the method on a computing node in a parallel computing system comprising: receiving, from a scheduler, a request with a key for managing preemption of a parallel application with a plurality of tasks running on at least one computing node in a multi-processor system as part of a parallel computing system, wherein the key has been previously associated to the parallel application, and wherein the key is associated with a plurality of tasks of the parallel application; accessing from a network resource table using the key, an address location of each task in the plurality of tasks associated with the parallel application; collecting a status for each of the tasks by completing the following sending a reply to the scheduler with an overall preemption related status of the parallel application based on the preemption related status entry for each of the tasks in the status table.
