Breaking boundary between CPU and GPU

This session will cover what is a memory address space, what it means to have different memory address space between CPU and GPU. A familiarity with existing compute API such as OpenCL or CUDA is expected (https://www.khronos.org/opencl/ or https://developer.nvidia.com/cuda-zone)

Threads on the GPU have their own memory address space, distinct from the CPU memory address space. This is one of the biggest issue for programmers wishing to leverage GPU. Programmers have to replicate their data structure in the GPU memory address space. New Linux kernel features and hardware features are now breaking this boundary and offer a unified memory address space for CPU and GPU. Programmers can share pointers between the two without having to do anything.
