GPUArrayQ

GPUArrayQ[g]

gives True if g is a valid GPUArray object and False otherwise.

Details

  • GPUArrayQ tests whether an input is a valid array stored in memory accessible for GPU-accelerated computation.

Examples

open all close all

Basic Examples  (2)

Test whether an object is a valid GPUArray object:

Wolfram Language code: GPUArray[{0., 0.5, 1., 1.5, 2., 2.5, 3., 3.5}]
Wolfram Language code: GPUArrayQ[%]

A list is not a valid GPUArray object:

Wolfram Language code: GPUArrayQ[{0., 0.5, 1., 1.5, 2., 2.5, 3., 3.5}]

Scope  (3)

GPUArrayQ works with vectors:

Wolfram Language code: GPUArray[{0., 0.5, 1., 1.5, 2., 2.5, 3., 3.5}]
Wolfram Language code: GPUArrayQ[%]

GPUArrayQ works with matrices:

Wolfram Language code: GPUArray[{{0., 0.5}, {1., 1.5}, {2., 2.5}, {3., 3.5}}]
Wolfram Language code: GPUArrayQ[%]

GPUArrayQ gives False for anything that is not a valid GPUArray object:

Wolfram Language code: GPUArrayQ[{1, 2, 3}]

Properties & Relations  (3)

ArrayQ gives True for valid GPUArray objects:

Wolfram Language code: GPUArray[{0., 0.5, 1., 1.5, 2., 2.5, 3., 3.5}]
Wolfram Language code: ArrayQ[%]

Use VectorQ to test whether a GPUArray object is a vector:

Wolfram Language code: GPUArray[{0., 0.5, 1., 1.5, 2., 2.5, 3., 3.5}]
Wolfram Language code: VectorQ[%]

Use MatrixQ to test whether a GPUArray object is a matrix:

Wolfram Language code: GPUArray[{{0., 0.5}, {1., 1.5}, {2., 2.5}, {3., 3.5}}]
Wolfram Language code: MatrixQ[%]
