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
Massive parallelization of multilevel fast multipole algorithm for 3-D electromagnetic scattering problems on SW26010 many-core cluster
Springer Science and Business Media LLC - - Trang 1-17 - 2023
Xin-Duo Liu, Wei-Jia He, Ming-Lin Yang, Xin-Qing Sheng
This paper presents a massively parallel approach of the multilevel fast multipole algorithm (PMLFMA) on homegrown many-core SW26010 cluster of China, noted as (SW-PMLFMA), for 3-D electromagnetic scattering problems. In this approach, the multilevel fast multipole algorithm (MLFMA) octree is first partitioned among management processing elements (MPEs) of SW26010 processors following the ternary ...... hiện toàn bộ

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
Cognitive social network analysis for supporting the reliable decision-making process
Springer Science and Business Media LLC - Tập 74 - Trang 3654-3665 - 2016
Mucheol Kim, Sangyong Han
With the advancement of the Internet and web technologies, social networks have gained attention as a new paradigm for user-centered information systems. As the amount of accessible information increases, the need for personalized information increases as well. Under such circumstances, social networks that are based on trust between users are increasingly utilized to provide efficient and reliabl...... 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
Dynamic Affinity Cluster Allocation in a Shared Disks Cluster
Springer Science and Business Media LLC - Tập 37 - Trang 47-69 - 2006
Kyungoh Ohn, Haengrae Cho
A shared disks (SD) cluster couples multiple computing nodes for high performance transaction processing, and all nodes share a common database at the disk level. In the SD cluster, a front-end router selects a node for an incoming transaction to be executed. An affinity-based routing can increase the buffer hit ratio of each node by clustering transactions referencing similar data to be executed ...... 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
Authentication and authorization infrastructure for Grids—issues, technologies, trends and experiences
Springer Science and Business Media LLC - Tập 52 - Trang 82-96 - 2009
Wei Jie, Junaid Arshad, Pascal Ekin
Authentication and authorization for Grids is a challenging security issue. In this paper, key issues for the establishment of Grid authentication and authorization infrastructures are discussed, and an overview of major Grid authentication and authorization technologies is presented. Related to this, recent developments in Grid authentication and authorization infrastructures suggest adoption of ...... hiện toàn bộ
