This paper focuses on matrix multiplication algorithm, particularly square parallel matrix multiplication using Computer Unified Device Architecture (CUDA) programming model with C programming language. Matrix
CUDAMatrix MultiplicationMultiphysics SimulationslibMeshMultiphysics systems are used to simulate various physics phenomena given by Partial Differential Equations (PDEs). The most popular method of solving PDEs is Finite Element method. The simulations require large amount of computational power, that is ...
Matrix Multiplication 本文主要介绍如何优化cuda的矩阵乘法,接近cublas库的性能。 naive version 思路:每个线程计算一个C中的元素 #define OFFSET(row, col, ld) ((row) * (ld) + (col))__global__voidnaiveSgemm(float*__restrict__a,float*__restrict__b,float*__restrict__c,constintM,constintN,cons...
In this case that is matrix multiplication: cublasdx::function::MM. Valid and sufficient description of the inputs and outputs: the dimensions of matrices (m, n, k), the precision (half, float, double etc.), the data type (real or complex) and the data arrangement of matrices (row- ...

编译和运行:确保你的系统已安装CUDA工具包,并使用nvcc编译器来编译这段代码。例如: bash nvcc matrixmultiplication.cu -o matrixmultiplication ./matrixmultiplication 这样,你就完成了CUDA矩阵乘法模板代码的补全,并且可以编译和运行它来验证矩阵乘法的正确性。
We focus on the design of kernels for sparse matrix-vector multiplication. Although CUDA kernels may be compiled into sequential code that can be run on any architecture supported by a C compiler, our SpMV kernels are designed to be run on throughput-oriented architectures in general and the ...
