- The CUDALink application must be loaded using Needs["CUDALink`"].
- CUDAMap works only on general vector types such as "Float", "Double", ….
- CUDAMap does not work on fixed vector structure types like "Float[2]", "Integer32[2]", ….
- CUDAMap does not work on symbolic input.
- CUDAMap is equivalent to Map.
- The value for f can be either Cos, Sin, Tan, ArcCos, ArcSin, ArcTan, Cosh, Sinh, Exp, Log, Log10, Sqrt, Ceiling, Floor, or Abs.

First, load the CUDALink application:
Needs["CUDALink`"]This maps the Cos operator on an input list:
CUDAMap[Cos, 1.0 * Range[10]]The above is equivalent to Map:
Map[Cos, 1.0 * Range[10]]The input can be CUDAMemory. This loads a list using CUDAMemoryLoad:
mem = CUDAMemoryLoad[Range[-10, 10], "Byte"]This applies Abs on the input memory:
res = CUDAMap[Abs, mem]The memory returned can be retrieved using CUDAMemoryGet:
CUDAMemoryGet[res]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:
CUDAMap[Cos, Range[10]]The above is not equivalent to Map:
Map[Cos, Range[10]]文本
