Flexible Parallel Algorithms for Big Data Optimization [PDF]

, 2013
We propose a decomposition framework for the parallel optimization of the sum of a differentiable function and a (block) separable nonsmooth, convex one.

Parallel Multidimensional Lookahead Sorting Algorithm

IEEE Access, 2019
This paper presents a new parallel structured lookahead multidimensional sorting algorithm. Our algorithm can be based on any sequential sorting algorithm. The amount of parallelism can be controlled using several parameters such as the number of threads,

Second-Order L1 Schemes for Fractional Differential Equations

Fractal and Fractional
Difference schemes for the numerical solution of fractional differential equations rely on discretizations of the fractional derivative. In this paper, we obtain the second-order expansion formula for the L1 approximation of the Caputo fractional ...

Main Memory Adaptive Indexing for Multi-core Systems

, 2014
Adaptive indexing is a concept that considers index creation in databases as a by-product of query processing; as opposed to traditional full index creation where the indexing effort is performed up front before answering any queries.

Dynamic Algorithms for the Massively Parallel Computation Model [PDF]

, 2019
The Massive Parallel Computing (MPC) model gained popularity during the last decade and it is now seen as the standard model for processing large scale data. One significant shortcoming of the model is that it assumes to work on static datasets while, in

GPGPU Implementation of a Genetic Algorithm for Stereo Refinement

International Journal of Interactive Multimedia and Artificial Intelligence, 2015
During the last decade, the general-purpose computing on graphics processing units Graphics (GPGPU) has turned out to be a useful tool for speeding up many scientific calculations. Computer vision is known to be one of the fields with more penetration of
