The present disclosure is directed to a method for managing tasks in a computer system having a plurality of CPUs. Each task in the computer system may be configured to indicate a migration ready indicator of the task. The migration ready indicator for a task may be given when the set of live data for that task reduces or its working set of memory changes. The method may comprise associating a migration readiness queue with each of the plurality of CPUs, the migration readiness queue having a front-end and a back-end; analyzing a task currently executing on a particular CPU, wherein the particular CPU is one of the plurality of CPUs; placing the task in the migration readiness queue of the particular CPU based on status of the task and/or the migration ready indicator of the task; and selecting at least one queued task from the front-end of the migration readiness queue of the particular CPU for migration when the particular CPU receives a task migration command.
