CUDASparseVector

CUDASparseVector[sparse,type]

yields a sparse vector of given type which resides on a CUDA enabled GPU.

Details and Options

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

Basic Examples  (1)

First, load the CUDALink application:

Wolfram Language code: Needs["CUDALink`"]

Create a sparse vector of data that lives on the GPU:

Wolfram Language code: vec = CUDASparseVector[ SparseArray[Table[{i} -> i, {i, 3}]], "Real64"]

Retrieve the data from a CUDASparseVector:

Wolfram Language code: Normal[vec]

Multiply a dense matrix into the sparse vector (the result also lives on the GPU):

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

Information  (1)

Information about the CUDA sparse vector:

Wolfram Language code: Information[CUDASparseVector[ SparseArray[Table[{i} -> i, {i, 3}]], "Real64"]]

Possible Issues  (1)

Normal of a CUDASparseVector is a SparseArray:

Wolfram Language code: cuspvec = CUDASparseVector[ SparseArray[Table[{i} -> i, {i, 3}]], "Real64"]; Normal[cuspvec]

To get the underlying data, Normal is applied twice:

Wolfram Language code: Normal[Normal[cuspvec]]
