Pointers on Kaveri APU

Jump to solution

As the Kaveri APUs support SVM, data structures can be directly shared between the CPU and the GPU (including pointers). In the past, pointers on the CPU-end cannot be interpreted by the GPU because they have different addressing space. Now with OpenCL 2.0 enabled and Omega driver available, is it possible to implement a data structure like linked list or binary tree on the CPU, and pass it to the GPU? Or could I create such a linked list or tree on the GPU directly?

You could generate these data structures on the GPU as long as the memory is allocated by the CPU before hand.
