Assigning Jobs to Heterogeneous Processing Modules

A processing system comprising:

• plural computing units,
• each computing unit being capable of executing plural threads, and
• each thread, performed by a particular computing unit, having a performance level that depends on a number of other threads that are simultaneously being executed by the particular computing unit;
• and
• a scheduling module configured to assign a new job to a thread having a highest performance level that is currently available.

A method, performed by a computer-implemented processing system, for scheduling jobs, comprising:

• receiving a new job by the processing system, the processing system having:
• plural processing modules,
• each processing module being characterized by a performance level that reflects a processing capability of the processing module, and
• at least two of the processing modules having different performance levels;
• assigning the new job to a processing module having a highest performance level that is currently available;
• and
• determining that a previously-assigned job has ended on a newly-vacated processing module having a vacated-module performance level, and, in response, reassigning a most-urgent in-progress job to the newly-vacated processing module, providing that the in-progress job is executing on a processing module having a lower performance level compared to the vacated-module performance level.
