A GPU-based out-of-core architecture for interactive visualization of AMR time series data
No full textCe manuscrit présente une approche de scalabilité pour de la visualisation in-téractive de série temporelle de Maillages à Raffinement Adaptatif (AMR) massives. Nouspouvons définir une donnée AMR comme un format de quadrillage dynamique de cellulesraffinées hiérarchiquement à partir d’un domaine de calcul décrit dans cette étude commeune grille cartésienne régulière. Cette caractéristique adaptative est essentielle pour suivredes phénomènes évolutifs dépendant du temps et fait du format AMR une représentationessentielle pour la simulation numérique 3D. Cependant, la visualisation des données desimulation numérique met en évidence un problème critique : l’augmentation significa-tive de l’empreinte mémoire des données générées, qui atteint des pétaoctets, dépassantainsi largement les capacités mémoire des cartes graphiques les plus récentes. La questionest donc de savoir comment accèder à ces données massives - les séries temporelles AMRen particulier - pour de la visualisation intéractive sur un simple poste de travail. Afinde répondre à cette problématique majeure, nous présentons une architecture out-of-corebasée GPU. Notre proposition est un système de cache basé sur un bricking ad-hoc identifiépar une indexation Space-Filling Curve (SFC) et gérée par une table de pagination baséeGPU qui charge les données AMR requises à la volée depuis le disque vers la mémoire duGPU.This manuscript presents a scalable approach for large-scale Adaptive Mesh Refinement (AMR) time series interactive visualization.We can define AMR data as a dynamic gridding format of cells hierarchically refined from a computational domain described in this study as a regular Cartesian grid.This adaptive feature is essential for tracking time-dependent evolutionary phenomena and makes the AMR format an essential representation for 3D numerical simulations.However, the visualization of numerical simulation data highlights one critical issue: the significant increases in generated data memory footprint reaching petabytes, thus greatly exceeding the memory capabilities of the most recent graphics hardware.Therefore, the question is how to access this massive data - AMR time series in particular - for interactive visualization on a simple workstation. To overcome this main problem, we present an out-of-core GPU-based architecture.Our proposal is a cache system based on an ad-hoc bricking identified by a Space-Filling Curve (SFC) indexing and managed by a GPU-based page table that loads required AMR data on-the-fly from disk to GPU memory

Curriculum, Teaching and Learning Within the Context of Comparative, International and Development Education
Get PDFCurriculum, teaching and learning should include a component of Comparative, International and Development Education. It is increasingly important for teachers to foster global citizenship, international cooperation and cross-cultural understanding, within the dialectic of the global and the local. By reaching beyond the four walls of classrooms, teachers can gain broader, international perspectives and a deeper sociocultural understanding of curriculum, teaching and learning. Thus, enriching student experience and substantially improving teacher professional development. While there are many potentially significant cross-cultural lessons in teaching pedagogy, teachers have few opportunities. However, through educational exchanges and shared experience, teachers can become introduced to alternative forms of schooling and can learn to think more critically about traditional approaches to education. In this paper, I propose using Comparative, International and Development Education to enhance teacher education and situate my own cross-cultural experiences in curriculum, teaching and learning in Canada and Japan within this context.Not peer reviewedThe published version in the this article is available: Howe, E.

Welcome from the IEEE PES ISGT Europe 2020 General Chairs
No full textWelcome from the IEEE PES ISGT Europe 2020 General Chairs On behalf of the Organizing Committee we are very pleased to welcome you to the 10th IEEE PES Innovative Smart Grid Technologies Europe (ISGT-Europe) Conference organized by the Delft University of Technology, the Netherlands, which for more than 175 years has been one of the most prestigious public institutions both at an international and national level in education, research, technological transfer and services in all sectors of engineering. The IEEE-PES ISGT-Europe 2020 conference will stress the need for viewing the role of smart grids in future energy systems as part of the designing, managing and operating qualitatively new complex socio-technical systems. From a technical perspective, solutions to the limited ability to predict stochastic generation and demand can be found in novel technologies such as integrated communications, advanced sensing & measurement technologies, advanced control methods, improved interfaces and decision support. From an economic and regulatory perspective, the challenge is to innovate and deploy new technologies within new business models and market designs, so that the objectives to contribute significantly to a sustainable world will be met. This is the first ISGT conference that is conducted in a virtual fashion. This is a challenge but also an opportunity. Although we would have preferred to welcome the ISGT community in the beautiful city of the Hague located in South-Holland, we are happy to host you virtually this time. We kept the classical format of a conference with regards to timing and content, and tried to replicate the interactive elements such as discussions or social interaction with on-line tools. Conferences are - besides learning the newest trends and developments - for meeting peers and networking after all. A clearly positive aspect of virtual conferences such as this one are reduced costs, both in conference organization (and in attendee fees ) and travel. Still, we hope that we will meet soon again face to face and enjoy a few days together. We would like to thank all the conference sponsors and everyone that supported us in setting this IEEE PES ISGT-Europe 2020 up, from IEEE PES, the Technical Review Committee to the local team at TU Delft and wish everyone a fruitful and engaging conference. We look forward to meeting you virtually at the 10th IEEE PES Innovative Smart Grid Technologies Europe (ISGT-Europe) Conference."Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public."Energie and IndustrieIntelligent Electrical Power Grid
