Description: This R&D proposal includes two complementary sub-projects aimed at investigating the energy efficiency of important parallel applications using a state-of-the-art high-performance computing system. The first sub-project focuses on proposing and evaluating architectural mechanisms and new computational techniques that enable a parallel seismic modeling application and extract maximum performance from the Santos Dumont supercomputer. In a parallel application, energy efficiency reflects the percentage of time that processors spend performing useful computation. Therefore, the second sub-project will evaluate new techniques to increase the energy efficiency of parallel applications using energy-efficient computing systems that employ an increasing number of multi-core processors, DVFS, and virtualization support.

Description: Development and integration of software for a scalable Video On Demand distribution system, accessible via wireless devices using WiFi technology, meeting defined security and quality of service requirements. The final product should enable access to digital video on demand via portable mobile devices (PDAs and notebooks) through wireless communication platforms. The potential applications of the technology to be provided are enormous. For example, the products obtained in this project will make it possible to produce videos for distribution for various purposes in localized (e.g., in defined communities) and/or geographically dispersed environments, using high-speed access.

Description: Development of a distributed shared memory system, called the NCP 2 parallel computer. The NCP 2 project maintained continuity with the NCPI computer and introduced advancements, primarily new hardware support for implementing the distributed shared memory model, in addition to utilizing the new T9000 and Intel i860P chips with up to one order of magnitude greater processing power than the NCP I. It also continued the advancement in R&D of numerical algorithms for large-scale applications in the areas of Computing, Engineering, Physics, and strategic areas. Finally, R&D was conducted to solve basic problems of parallel computing related to the construction of distributed Operating Systems, programming languages, and parallel programming environments.
