Hi everybody,
i have a doubt about global memory.
I don’t understand if each OpenCL device has its own global memory or if global memory is a generic region of the whole system.
By looking the OpenCL specification 2.1 ( https://www.khronos.org/registry/cl/specs/opencl-2.1.pdf) at page 39 it seems that the global memory is a region shared between all the possible OpenCL devices, and not a part of each device.
Instead, by looking the OpenCL specification 1.0 (https://www.khronos.org/registry/cl/specs/opencl-1.0.pdf) at page 25 it seems that a specific OpenCL device integrates its own global memory.
So, can someone help me to understand where the global memory resides ?
