Basic Examples  (2)

First, load the CUDALink application:

This maps the Cos operator on an input list:

The above is equivalent to Map:

The input can be CUDAMemory. This loads a list using CUDAMemoryLoad:

This applies Abs on the input memory:

The memory returned can be retrieved using CUDAMemoryGet:

Possible Issues  (1)

The output type is the same as the input. If the input is a list of integers, then the decimals are dropped:

The above is not equivalent to Map:
