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

Description

This function computes the matrix-matrix multiplication (X * Y) by using CUDA cublas function cublasDgemm

Usage

mmgpu(X, Y)

Arguments

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

Value

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

• ptr: GPU pointer

• m: matrix X's number of rows

• n: matrix Y's number of columns
