Kind Code:
A1
Abstract:
Described is a machine-readable storage medium having instructions stored thereon, that when executed, cause a processor to perform a method which comprises: grouping two or more work groups to form a super-workgroup; and partitioning a portion of a memory space into one or more super-shared local memories (Super-SLMs), wherein the memory space shared within the super-workgroup forms at least one Super-SLM of the one or more Super-SLMs. Described is an apparatus which comprises: a plurality of execution units; a cache memory having a portion characterized as a SLM which is shared with the plurality of execution units at least one of which is to operate on a work group of a sub-slice, wherein the SLM is shared within the work group; and at least one Super-SLM for providing shared memory accessible by different work groups in the sub-slice, wherein the at least one of the execution units is to operate on the different work groups.
