Application programming interfaces for data parallel computing on multiple processors

A parallel computing system comprising:

• a host processor;
• one or more compute units coupled to the host processor;
• a memory coupled to at least one of the host processor and the one or more compute units, wherein a parallel computing program is stored in the memory, the parallel computing program including calls to one or more APIs (application programming interface) for the host processor to perform:
• generating a program object corresponding to a source code for a data processing task;
• generating executable codes from the program object for the one or more compute units;
• and
• loading the executable codes to be executed concurrently among the one or more compute units to perform the data processing task,
• wherein the loading of the executable codes comprises:
• generating a kernel object associated with a function name identifying a function implementing the data processing task in the source codes, the kernel object including storage for arguments of the function;
• and
• scheduling execution of the executable codes among the one or more compute units, wherein the execution including number of threads in a thread group to execute one of the executable codes concurrently in at least one of the one or more compute units.

A machine readable non-transitory storage medium storing a plurality of tokens comprising:

• host function tokens corresponding to one or more APIs (application programming interfaces) for a host processor to perform one or more host functions including:
• selecting one or more compute units coupled to the host processor based on processing requirements specified through the one or more APIs;
• generating a program object corresponding to a source code for a data processing task, the source code for the data processing task being specified through the one or more APIs;
• generating executable codes from the program object for one or more compute units coupled to the host processor, the program object for the generation of the executable codes being specified through the one or more APIs;
• and
• loading the executable codes to be executed concurrently among the one or more compute units to perform the data processing task;
• and
• kernel function tokens corresponding to the source code for the data processing task.
