I am starting to use the GPUs on the VIM3. The clinfo info command indicates that the GPU is configured as 1 device with 2 compute units and can support a maximum work group size of 384 with a work item dimension of 3.
I was under the impression that there were 4 GPU cores. Is this incorrect?
Do the two compute units each map to a GPU core? If not, what is the mapping from compute units to cores?
Does the work group size of 384 map to a number of shader cores in each compute unit?
How does the work item dimension of 3 map to a platform/physical core model for your implementation of OPENCL on the VIM3?
