Advanced Computer Architecture for Exascale Computing: The AMD Research Perspective

Place: ISCTE-IUL Room: J.J. Laginha Auditorium

Sponsor: ISTAR Lab, IUL

The need for ever more powerful supercomputers does not appear to be slowing down, but the challenges to push computing to exaFLOP levels and beyond are becoming increasingly difficult. Targets for computing throughput, memory capacity, memory bandwidth, power efficiency, reliability, and cost make the construction of an Exascale machine to be a significant challenge. In this talk, I will first present an overview of current AMD technologies, and then I will describe one possible vision for a processor architecture that can be used to construct Exascale systems. We describe a conceptual Exascale Node Architecture (ENA), which is a computational building block for an Exascale supercomputer. The ENA consists of an Exascale Heterogeneous Processor (EHP) coupled with an advanced memory system. The conceptual EHP provides a high-performance accelerated processing unit (CPU+GPU), in-package high-bandwidth 3D memory, and aggressive use of die-stacking and chiplet technologies to meet the requirements for Exascale computing in a balanced manner. In addition to detailing our approach, I will also discuss some of the remaining open research challenges for the community.

European Researchers Night 2017

Last Friday we have been at the European Researchers Night 2017 presenting articles about the advantages of using Gamification and Robotics in programming learning process.

CISTI 2017: ISCTE-IUL ACM Student Chapter participation

The ISCTE-IUL ACM Student Chapter participated in the CISTI 2017, the largest conference in Portuguese and Spanish in the field of Information Technology and Information Systems.

In fact, the student chapter had a stand in the conference place, where Joao Aparicio, Joao Sequeira, Andre Pereira and Antonio Teixeira represented the ACM Student chapter.

ACM student chapter members had a significant scientific participation.  In fact, Fernando Bento, Martinha Piteira, Joao Papricio, Catarina Santos, Sofia Aparicio and Hugo Araujo co-authored several papers presented at the conference. Fernando Bento, Martinha Piteira, Catariana Santos and Hugo Araujo presented papers at the conference.

Presentation of Undergraduate Research Project Proposals

Several students presented undergraduate research project proposals during research week.

The ACM chair (Joao Aparicio) presented a project related to autonomous driving. Andre Freire presented a project related to computer programming learning.

Web Applications and Usability: a Project using WordPress CMS

Last Monday (May 22th), students of Web Applications and Usability course (Postgraduate Program of Informatics Applied to Organizations – ISCTE-IUL) presented one of the projects consisting of developing an organizational website. Students were encouraged to develop the project using WordPress. Prof. Manuela Aparicio supported the students in WordPress customization. In the course, students also learned Javascript, CSS, PHP, and Mysql, allowing them to create a small plug-in. They also used UX and usability concepts and techniques in the process of development and evaluation of the website.

The students were organized in the following working groups (or teams):

  • Team 1: Fátima Tomé, Pedro Dias, Pedro Calado, Patricia Nobrega
  • Team 2: Miguel Afonso, Fabio Damil
  • Team 3: Ana Massano, Sérgio Aires
  • Team 4: Cátia Henriques, Ângela Freixo, Catarina Canteiro, André Mendes
  • Team 5: Carla Silva, Ana Sofia Graça, Cláudia Souza
  • Team 6: Diana Teixeira, Melissa Garcia, Sandra Ricardo
  • Team 7: Volodymyr Mykhayliv, João Sardinha, Rafael Moisés, André Bolila
  • Team 8: Olena Mandzyuk,Nuno Mendes, Brenardo Pereira
  • Team 9: Maria Nunes, Cláudia Ferreira

Master Lecture: Logistics & Robotics

João Sequeira and João Aparicio gave a lecture about Logistics and Robotics to a class of  students from the IBS (ISCTE Business School). In this lecture, João Sequeira and João Aparicio  introduced main robotics concepts to the students in the course of Information Systems and ERP (Master of Services and Technology Management). They also discussed possible impacts of using robotics in factories and warehouses.  João Aparicio also talked about his experience in robot competition.
