If each workgroup uses 16kBytes you may have up to 4 workgroups on the CU. 2) There are 256 registers per SIMD unit (1/4 CU). If each wavefront uses 16 registers you may have to 16 wavefronts on the SIMD unit, or 64 for the CU.
WebEach PE is capable of performing the standard arithmetic and logical operations. In addition, each PE knows its index. 2) Each PE has some local memory. 3) The PE's are synchronized and operate under the control of a single instruction stream. This instruction stream is generated by the control unit which has access to the program that is to be ... WebEach PE in our parallel summation algorithm in the previous section has only access to its own local memory. Access to data stored in the memory of another PE needs to be implemented by an explicit communication step. This type of parallel computer architecture is called a distributed memory system. Fig. 1.7 (A) illustrates its general design.
