I’m doing some performance tests on my Nvidia Quadro FX 1700 : I want to compute the GFlops / sec number during my program execution. My cuda code : __global__ void matrixMulKernel( float* A, float* B, float* C, int N) { int bx = blockIdx.x; int by = blockIdx.y; int tx...
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。

Efficient Sparse Matrix-Vector Multiplication on CUDA Nathan Bell∗ and Michael Garland† December 11, 2008 Abstract The massive parallelism of graphics processing units (GPUs) offers tremendous performance in many high-performance computing applications. While dense linear algebra readily maps to such...

CUDA Programming Guide Version 1.1 69 Chapter 6. Example of Matrix Multiplication // Device multiplication function called by Mul() // Compute C = A * B // wA is the width of A // wB is the width of B __global__ void Muld(float* A, float* B, int wA, int wB,...
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 ...
Results have been compared with results obtained by classic Central Processing Unit (CPU) matrix multiplication algorithm. The comparison shows that matrix multiplication on GPU significantly outperforms classic CPU approach. 展开 关键词: CUDA Matrix Multiplication Multiphysics Simulations libMesh ...
