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"

First, load the CUDALink application:

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

Retrieve the data from a CUDASparseVector:

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

Normal of a CUDASparseVector is a SparseArray:

To get the underlying data, Normal is applied twice:
