Abstract
Techniques are disclosed relating to context switching using distributed compute workload parsers. In some embodiments, an apparatus includes a plurality of shader units configured to perform operations for compute workgroups included in compute kernels, a plurality of distributed workload parser circuits each configured to dispatch workgroups to a respective set of the shader units, a communications fabric, and a master workload parser circuit configured to communicate with the distributed workload parser circuits via the communications fabric. In some embodiments, the master workload parser circuit maintains a first set of master state information that does not change for a compute kernel based on operations by the shader units and a second set of master state information that may be changed by operations specified by the kernel. In some embodiments, the master workload parser circuit performs a multi-phase state storage process in communications with the distributed workload parser circuits.
