What is the relation between Mali shader core and OpenCL work-group

hiwu

Hi all:

I use a RK3288 with mali T760 MP4 board. T760 has 16 shader core.
(1) Is there 64 shader core (16*4) in mali T760 MP4?
(2) Does one opencl work-group use more than 1 shader core ?

Thank you

    Mali-T760 supports up to 16 shader cores / 16 pixels per clock, the "MP" number is the number of shader cores implemented, so in the case of the RK3288 it has 4 shader cores.

    In general workgroups are small enough that one or more workgroups will run on a single shader core at a time, with multiple cores running other workgroups in parallel.
