CUDADot
CUDADot[vec1,vec2]
gives the dot product of vec1 and vec2.
CUDADot[mat,vec]
gives the matrix-vector product of mat and vec.
CUDADot[mat1,mat2]
gives the matrix-matrix product of mat1 and mat2.

- The CUDALink application must be loaded using Needs["CUDALink`"].
- CUDADot works only on general vectors types such as "Float", "Double", ….
- CUDADot does not work on fixed vector structure types like "Float[2]", "Integer32[2]", ….

First, load the CUDALink application:
Needs["CUDALink`"]This performs matrix-matrix multiplication:
CUDADot[Table[i, {i, 10}, {j, 10}], Table[i, {i, 10}, {j, 10}]]//MatrixFormThis performs matrix-vector multiplication:
CUDADot[Table[i, {i, 10}, {j, 10}], Range[10]]//MatrixFormThis performs the dot product:
CUDADot[Range[10], Range[10]]If input is CUDAMemory, then memory is returned as output:
A = CUDAMemoryLoad[RandomReal[1, {3, 3}]];
B = CUDAMemoryLoad[RandomReal[1, {3, 3}]];This multiplies the two input memories together:
res = CUDADot[A, B]Memory is retrieved using CUDAMemoryGet:
CUDAMemoryGet[res]//MatrixFormMemory must be freed with CUDAMemoryUnload:
CUDAMemoryUnload[A, B]文本
