# 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.
