CUDAMatrix

CUDAMatrix[data]

yields a matrix of data which resides on a CUDA enabled GPU.

CUDAMatrix[data,type]

yields a matrix of the specified type.

Details and Options

  • The CUDALink application must be loaded using Needs["CUDALink`"].
  • The resources used by a CUDAMatrix are automatically reclaimed from the GPU when they are no longer used.
  • The data in a CUDAMatrix can be retrieved by Normal.
  • A number of functions accept and return CUDAMatrix objects allowing operations to work with data that stays on the GPU.
  • Possible types for CUDAVector are:
  • "Integer32""Real32""ComplexReal32"
    "Integer64""Real64""ComplexReal64"
