System, method, and computer program product to enable the yielding of threads in a graphics processing unit to transfer control to a host processor

A computer-readable storage medium storing instructions that, when executed by a processor, causes the processor to perform steps comprising:

• receiving an intermediate representation of a program;
• replacing a yield instruction in the intermediate representation with a yield operation that includes one or more instructions;
• and
• compiling at least a portion of the modified intermediate representation into a machine code for execution on a parallel processing unit.

A system, comprising:

• A parallel processing unit;
• and
• a host processor, coupled to the parallel processing unit, that executes a compiler configured to:
• receive an intermediate representation of a program,
• replace a yield instruction in the intermediate representation with a yield operation that includes one or more instructions, and
• compile at least a portion of the modified intermediate representation into a machine code for execution on the parallel processing unit.
