CUDAFunction[args]

represents a function loaded using CUDAFunctionLoad.

更多信息和选项更多信息
  • The CUDALink application must be loaded using Needs["CUDALink`"].
  • CUDAFunction is returned by CUDAFunctionLoad.
  • A CUDAFunction object can be used the same way as a pure function.
  • The function represented by CUDAFunction runs in the same process as the Wolfram Language kernel.
  • The function represented by CUDAFunction is unloaded when the Wolfram Language kernel exits.
  • CUDAFunctionInformation returns information about the CUDAFunction.
  • On launch, if the number of threads is not specified (as an extra argument to the CUDAFunction), then the dimension of the element with largest rank and dimension is chosen. For images, the rank is set to 2.
  • On launch, if the number of threads is not a multiple of the block dimension, then it is incremented to be a multiple of the block dimension.
  • 范例

    基本范例  (1)

    First, load the CUDALink application:

    In[1]:=
    Click for copyable input

    This loads a function from the CUDA source:

    In[2]:=
    Click for copyable input
    Out[2]=

    This calls the function:

    In[3]:=
    Click for copyable input
    Out[3]=

    This gives information about the CUDA function:

    In[4]:=
    Click for copyable input
    Out[4]=
