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"

Basic Examples  (1)

First, load the CUDALink application:

Wolfram Language code: Needs["CUDALink`"]

Create a matrix of data that lives on the GPU:

Wolfram Language code: mat = CUDAMatrix[ {{1., 2., 3.}, {4., 5., 6.}, {7., 8., 9.}}]

Compute a dot product on the GPU (the result also resides on the GPU):

Wolfram Language code: CUDADot[mat, mat]

Retrieve the data from a CUDAMatrix:

Wolfram Language code: Normal[mat]

Scope  (1)

Information  (1)

Information about the CUDA matrix:

Wolfram Language code: Information[CUDAMatrix[ {{1., 2., 3.}, {4., 5., 6.}, {7., 8., 9.}}]]

Possible Issues  (1)

Normal of a CUDAMatrix is a NumericArray:

Wolfram Language code: cumat = CUDAMatrix[{{1., 2., 3.}}]; Normal[cumat]

To get the underlying data, Normal is applied twice:

Wolfram Language code: Normal[Normal[cumat]]
