Local launch in workgroup processors

An apparatus comprising:

• a shader engine comprising a plurality of workgroup processors configured to execute shader threads and a shader program interface (SPI) configured to assign the shader threads to execute at one or more of the workgroup processors;
• and
• a local launcher associated with a workgroup processor of the plurality of workgroup processors, wherein the local launcher is configured to perform one or more tasks in response to an application programming interface (API) call associated with utilizing the local launcher.

A method comprising:

• launching a shader thread at a workgroup processor of a shader engine using a local launcher associated with both the workgroup processor and a shader program interface (SPI) configured to assign shader threads to execute at the shader engine, wherein launching comprises assigning a shader thread to execute at the workgroup processor and allocating one or more resources of the shader engine to the workgroup processor, and wherein launching the shader thread using the local launcher is performed in response to an application programming interface (API) call associated with utilizing the local launcher.
