1 概述 稀疏线性方程组的求解是自然科学中许多实际问题求解 的关键技术.稀疏线性方程组求解中的核心计算子程序是稀 疏矩阵向量乘(Sparse Matrix Vector Multiply, SMVM),其运行 时间往往占到方程组求解的 90%以上.由于矩阵 A 是高度稀 疏的,在基于 cache 架构的通用处理器 (General Purpose Processor, GPP)上求...
A sparse matrix implementation of Whittaker-Eilers smoothing and interpolation - AnBowell/whittaker-eilers
The future direction of this work is threefold: first, the sparse nature of many classification problems requires investigating the effect of the integration of sparse data structures and sparse matrix and vector multiplications on the GPU SVM implementation. Second, it is necessary to extend this GP...
and thelogic unitsare distributed to form many processing elements (PE) to fully utilize the onboard resource. The processing elements can perform partition to the data matrix and divide them into groups, and the work groups can run in parallel while each partition has an internal pipeline desig...
In-memory computing, in which computation is performed at the data storage, has been proposed to accelerate the speed of NN computation and address the von Neumann bottleneck3,4. Vector-matrix multiplication (VMM), which requires the multiplication of two numbers, is one of the main functions ...
These leakage points can then be used to replace the entire segment of the power trace, to construct the correlation coefficient matrix. It should be noted that the above description is based on ideal conditions. However, in practical applications, there is often some delay in the data. ...
This implementation uses a custom graph format, namely binary compressed sparse row (BCSR) format for efficiency and reduced memory usage. Converter for three common graph formats (MATLAB sparse matrix, adjacency list, edge list) can be found in the root directory of the project. Usage: $ conv...
