COOPERATIVE THREAD ARRAY GRANULARITY CONTEXT SWITCH DURING TRAP HANDLING

Techniques are provided for restoring thread groups in a cooperative thread array (CTA) within a processing core. Each thread group in the CTA is launched to execute a context restore routine. Each thread group, executes the context restore routine to restore from a memory a first portion of context...

description Techniques are provided for restoring thread groups in a cooperative thread array (CTA) within a processing core. Each thread group in the CTA is launched to execute a context restore routine. Each thread group, executes the context restore routine to restore from a memory a first portion of context associated with the thread group, and determines whether the thread group completed an assigned function prior to executing the context restore routine. If the thread group completed an assigned function prior to executing the context restore routine, then the thread group exits the context restore routine. If the thread group did not complete the assigned function prior to executing the context restore routine, then the thread group executes one or more operations associated with a trap handler routine. One advantage of the disclosed techniques is that the trap handling routine operates efficiently in parallel processors.
