vectorAddMMAP - Vector Addition cuMemMap

Description

This sample replaces the device allocation in the vectorAddDrv sample with cuMemMap-ed allocations. This sample demonstrates that the cuMemMap api allows the user to specify the physical properties of their memory while retaining the contiguous nature of their access, thus not requiring a change in their program structure.

Key Concepts

CUDA Driver API, Vector Addition, MMAP
