CUDA new delete

Question

Can someone give a clear explanation of how the new and delete keywords would behave if called from __device__ or __global__ code in CUDA 4.2?

Answer 1

C++ new and delete operate on device heap memory. The device allows for a portion of the global (i.e. on-board) memory to be allocated in this fashion. new and delete work in a similar fashion to device malloc and free.

You can adjust the amount of device global memory available for the heap using a runtime API call.

CC 2.0 or greater is required for these capabilities.
