mvGPU: mvgpu

In yuanli22/RCUDA: GPU Enabled BLAS, LAPACK, Statistical Functions and Random Number Generators

Description

This function computes the matrix-vector multiplication (X * y) by using CUDA cublas function cublasDgemv

Usage

mvgpu(X, y)

Arguments

X	input matrix; list of R external GPU pointer and dimension
y	input vector; list of R external GPU pointer and dimension

Value

matrix-vector multiplication (X * y), a list consisting of

• ptr: GPU pointer

• m: matrix X's number of rows

• n: matrix X's number of columns; vector y's number of elements

Examples

a <- 1:4
b <- 2:3
a_gpu <- creategpu(a, 2, 2)
b_gpu <- creategpu(b)
mvgpu(a_gpu, b_gpu) -> c_gpu
gathergpu(c_gpu)
