Asynchronous execution mechanism

A method to facilitate asynchronous execution at a processing unit, comprising:

• detecting independent task passes that may be executed out of order in a pipeline of the processing unit;
• scheduling a first set of processing tasks to be executed at a first set of processing elements at the processing unit;
• and
• scheduling a second set of tasks to be executed at a second set of processing elements, wherein execution of the first set of tasks at the first set of processing elements is to be performed simultaneous and in parallel to execution of the second set of tasks at the second set of processing elements.

At least one computer readable medium having instructions stored thereon, which when executed by one or more processors, cause the processors to:

• detect independent task passes that may be executed out of order in a pipeline of the processing unit;
• schedule a first set of processing tasks to be executed at a first set of processing elements at the processing unit;
• and
• schedule a second set of tasks to be executed at a second set of processing elements, wherein execution of the first set of tasks at the first set of processing elements is to be performed simultaneous and in parallel to execution of the second set of tasks at the second set of processing elements.
