On Extensions of Limited Memory Steepest Descent Method
Qinmeng Zou, Frederic Magoules
We present some extensions to the limited memory steepest descent method based on spectral properties and cyclic iterations. Our aim is to show that it is possible to combine sweep…
Recent Developments in Iterative Methods for Reducing Synchronization
Qinmeng Zou, Frederic Magoules
On modern parallel architectures, the cost of synchronization among processors can often dominate the cost of floating-point computation. Several modifications of the existing meth…
Fast Gradient Methods with Alignment for Symmetric Linear Systems without Using Cauchy Step
Qinmeng Zou, Frederic Magoules
The performance of gradient methods has been considerably improved by the introduction of delayed parameters. After two and a half decades, the revealing of second-order informatio…
Parameter Estimation in the Hermitian and Skew-Hermitian Splitting Method Using Gradient Iterations
Qinmeng Zou, Frederic Magoules
This paper presents enhancement strategies for the Hermitian and skew-Hermitian splitting method based on gradient iterations. The spectral properties are exploited for the paramet…
Asynchronous Time-Parallel Method based on Laplace Transform
Frederic Magoules, Qinmeng Zou
Laplace transform method has proved to be very efficient and easy to parallelize for the solution of time-dependent problems. However, the synchronization delay among processors im…
GPU Accelerated Contactless Human Machine Interface for Driving Car
Frederic Magoules, Qinmeng Zou
In this paper we present an original contactless human machine interface for driving car. The proposed framework is based on the image sent by a simple camera device, which is then…
