使用CUDA实现块稀疏矩阵向量乘(BSpMV) 本文对Georgii Evtushenko的Block Sparse Matrix-Vector Multiplication with CUDA[1]这篇博客进行了部分汉化,其给出的代码有一点小问题,需要改一下。该篇博客是对《Optimization of Block Sparse Matrix-Vector Multiplication on Shared-Memory Parallel Architectures》[2]这篇论...
New CUSPARSE library of GPU-accelerated sparse matrix routines for sparse/sparse and dense/sparse operations delivers 5x to 30x faster performance than MKL New CURAND library of GPU-accelerated random number generation (RNG) routines, supporting Sobol quasi-random and XORWOW pseudo-random routines at...
The matrix represents a finite-difference approximation to the Laplacian operator on a 5-by-5 mesh. of sparse matrix-vector multiplication, we are not concerned with modifying matrices, we will only consider static sparse matrix formats, as opposed to those suitable for rapid insertion and ...
疎行列の乗算 (SpGEMM: Sparse-Sparse Matrix Multiplication) に必要なワークスペースを削減するために、NVIDIA はメモリ使用量の少ない 2 つの新しいアルゴリズムをリリースしています。最初のアルゴリズムは中間積の数を厳密に制限して計算し、2 番目のアルゴリズムは計算を復数のチャンクで分...

问用cuSPARSE实现CUDA中的稀疏矩阵乘法EN说明：这一段时间用Matlab做了LDPC码的性能仿真，过程中涉及了大量的矩阵运算，本文记录了Matlab中矩阵的相关知识，特别的说明了稀疏矩阵和有限域中的矩阵。Matlab的运算是在矩阵意义下进行的，这里所提到的是狭义上的矩阵，即通常意义上的矩阵。
Algorithms for which data addresses are not known beforehand, such as physics solvers, raytracing, and sparse matrix multiplication especially benefit from the cache hierarchy. Filter and convolution kernels that require multiple SMs to read the same data also benefit. 50% 0% GT200 Architecture ...
