PPT-Multicore: performance prediction of OpenMP applications using reuse profiles and analytical modeling
Springer Science and Business Media LLC - Tập 78 - Trang 2354-2385 - 2021
Atanu Barai, Yehia Arafa, Abdel-Hameed Badawy, Gopinath Chennupati, Nandakishore Santhi, Stephan Eidenbenz
We present PPT-Multicore, an analytical model embedded in the Performance Prediction Toolkit (PPT) to predict parallel applications’ performance running on a multicore processor. PPT-Multicore builds upon our previous work towards a multicore cache model. We extract LLVM basic block labeled memory trace using an architecture-independent LLVM-based instrumentation tool only once in an application’s...... hiện toàn bộ
Accelerating number theoretic transform in GPU platform for fully homomorphic encryption

Improving drug discovery through parallelism
Springer Science and Business Media LLC - - 2023
Jerónimo S. García, Savíns Puertas-Martín, Juana L. Redondo, Juan José Moreno, Pilar M. Ortigosa
Compound identification in ligand-based virtual screening is limited by two key issues: the quality and the time needed to obtain predictions. In this sense, we designed OptiPharm, an algorithm that obtained excellent results in improving the sequential methods in the literature. In this work, we go a step further and propose its parallelization. Specifically, we propose a two-layer parallelizatio...... hiện toàn bộ
Performance-enhanced real-time lifestyle tracking model based on human activity recognition (PERT-HAR) model through smartphones
Springer Science and Business Media LLC - Tập 78 - Trang 5241-5268 - 2021
K. Ishwarya, A. Alice Nithya
The identification of human actions and their representation and categorization in an automated system through training and learning is considered the human activity recognition (HAR) process. Tracking systems capture and read human actions ranging from the identification of plain movements to the comprehension of habits and practices. As such, HARs have found their use in areas such as health car...... hiện toàn bộ
A cloud-based face video retrieval system with deep learning
Springer Science and Business Media LLC - Tập 76 - Trang 8473-8493 - 2020
Feng-Cheng Lin, Huu-Huy Ngo, Chyi-Ren Dow
Face video retrieval is an attractive research topic in computer vision. However, it remains challenges to overcome because of the significant variation in pose changes, illumination conditions, occlusions, and facial expressions. In video content analysis, face recognition has been playing a vital role. Besides, deep neural networks are being actively studied, and deep learning models have been w...... hiện toàn bộ
An optimization approach for cloud composite services
Springer Science and Business Media LLC - Tập 78 - Trang 3621-3645 - 2021
Aida Lahouij, Lazhar Hamel, Mohamed Graiet
Recently, a considerable literature has grown up around the theme of composite services verification. Namely, the verification of the non-functional aspect generally consisting of optimizing the quality of service (QoS) of the composite service. Great efforts have been devoted to the study of several optimization methods and their impact on the QoS of the composite service. Guaranteeing the servic...... hiện toàn bộ
Modeling and simulation of parallel adaptive divide-and-conquer algorithms
Springer Science and Business Media LLC - Tập 43 - Trang 241-255 - 2007
Fernando J. Barros
Conventional modeling and simulation formalisms only give support to the representation of model behavior, providing no constructs for describing changes in model structure. However, some systems are better modeled by self-reconfigurable formalisms. We have developed the Discrete Flow System Specification (DFSS) to exploit dynamic structure, component-based and hierarchical model construction. Du...... hiện toàn bộ
Energy optimized container placement for cloud data centers: a meta-heuristic approach
Springer Science and Business Media LLC - Tập 80 - Trang 98-140 - 2023
Avita Katal, Tanupriya Choudhury, Susheela Dahiya
The cloud-computing paradigm based on containers has progressively grown in recent years as a flexible strategy that has proven to be energy efficient. The increasing usage of the container as a service technology in data centers (DCs) among cloud providers highlights the necessity of the container installation design phase in cloud environments. Cloud providers attempt to enhance resource utiliza...... hiện toàn bộ

A genetic mixed-integer optimization of neural network hyper-parameters
Springer Science and Business Media LLC - Tập 78 - Trang 14680-14702 - 2022
Kyle Spurlock, Heba Elgazzar
Neural networks (NN) have become immensely popular for their effectiveness and flexibility in learning complicated patterns. Despite this success, they are often considered difficult to design because of the wide variety of parameters they require. Determining the most optimal selection of parameters has become tedious and costly, and neural architecture search (NAS) methods have been employed to ...... hiện toàn bộ
