CUDAVector

CUDAVector[data]

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

CUDAVector[data,type]

yields a vector of the specified type.

Details and Options

  • The CUDALink application must be loaded using Needs["CUDALink`"].
  • The resources used by a CUDAVector are automatically reclaimed from the GPU when they are no longer used.
  • The data in a CUDAVector can be retrieved by Normal.
  • A number of functions accept and return CUDAVector 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 vector of data that lives on the GPU:

Wolfram Language code: vec = CUDAVector[ {1., 2., 3.}]

Compute a dot product on the GPU:

Wolfram Language code: CUDADot[vec, vec]

Retrieve the data from a CUDAVector:

Wolfram Language code: Normal[vec]

Information  (1)

Information about the CUDA vector:

Wolfram Language code: Information[CUDAVector[ {1., 2., 3.}]]

Possible Issues  (1)

Normal of a CUDAVector is a NumericArray:

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

To get the underlying data, Normal is applied twice:

Wolfram Language code: Normal[Normal[cuvec]]
