OPENCL MEMORY MODEL<br />
•Private Memory<br />
–Per work-item<br />
•Local Memory<br />
–Shared <strong>with</strong>in a workgroup<br />
•Global/Constant Memory<br />
–Visible to all workgroups<br />
•Host Memory<br />
–On the CPU<br />
Memory management is Explicit<br />
You must move data from host -> global -> local … and back<br />
