Harnessing Performance Variability in Embedded and High-performance Many/Multi-core Platforms: A Cross-layer Approach

Description

This book describes the state-of-the art of industrial and academic research in the architectural design of heterogeneous, multi/many-core processors. The authors describe methods and tools to enable next-generation embedded and high-performance heterogeneous processors to confront cost-effectively the inevitable variations by providing Dependable-Performance: correct functionality and timing guarantees throughout the expected lifetime of a platform under thermal, power, and energy constraints. Various aspects of the reliability problem are discussed, at both the circuit and architecture level, the intelligent selection of knobs and monitors in multicore platforms, and systematic design methodologies. The authors demonstrate how new techniques have been applied in real case studies from different applications domain and report on results and conclusions of those experiments. Enables readers to develop performance-dependable heterogeneous multi/many-core architectures Describes system software designs that support high performance dependability requirements Discusses and analyzes low level methodologies to tradeoff conflicting metrics, i.e. power, performance, reliability and thermal management Includes new application design guidelines to improve performance dependability Front Matter ....Pages i-x The HARPA Approach to Ensure Dependable Performance (Nikolaos Zompakis, Michail Noltsis, Panagiota Nikolaou, Panayiotis Englezakis, Zacharias Hadjilambrou, Lorena Ndreu et al.)....Pages 1-19 Front Matter ....Pages 21-21 Trends in Processor Architecture (Antonio González)....Pages 23-42 Aging Effects: From Physics to CAD (Hussam Amrouch, Heba Khdr, Jörg Henkel)....Pages 43-69 Front Matter ....Pages 71-71 The HARPA-OS (Simone Libutti, Giuseppe Massari, William Fornaciari)....Pages 73-105 Event-Based Thermal Control for High Power Density Microprocessors (Federico Terraneo, Alberto Leva, William Fornaciari)....Pages 107-127 Front Matter ....Pages 129-129 HARPA RT (Dimitrios Rodopoulos, Nikolaos Zompakis, Michail Noltsis, Francky Catthoor, Dimitrios Soudris)....Pages 131-150 Improving Robustness of a Real-Time Spectrum Sensing Application with the HARPA Run-Time Engine (Hans Cappelle, Michail Noltsis, Simone Corbetta, Francky Catthoor)....Pages 151-164 Front Matter ....Pages 165-165 Evaluating System-Level Monitors and Knobs on Real Hardware (Panagiota Nikolaou, Zacharias Hadjilambrou, Panayiotis Englezakis, Lorena Ndreu, Chrysostomos Nicopoulos, Yiannakis Sazeides et al.)....Pages 167-186 Monitor and Knob Techniques in Network-on-Chip Architectures (Davide Zoni, Panayiotis Englezakis, Kypros Chrysanthou, Andrea Canidio, Andreas Prodromou, Andreas Panteli et al.)....Pages 187-213 Front Matter ....Pages 215-215 Time-Efficient Modeling and Simulation of True Workload Dependency for BTI-Induced Degradation in Processor-Level Platform Specifications (Simone Corbetta, Pieter Weckx, Dimitrios Rodopoulos, Dimitrios Stamoulis, Francky Catthoor)....Pages 217-235 Proof-of-Concept HARPA Measurement-Based Platform Modelling Framework (Simone Corbetta, Wim Meeus, Etienne Cappe, Francky Catthoor, Agnes Fritsch)....Pages 237-261 Front Matter ....Pages 263-263 Floreon+ Modules: A Real-World HARPA Application in the High-End HPC System Domain (Antoni Portero, Radim Vavrik, Martin Golasowski, Jiri Sevcik, Giuseppe Massari, Simone Libutti et al.)....Pages 265-293 Beesper SmartBridge: A Real-World HARPA Application in the Low-End Embedded System Domain (Federico Sassi, Alessandro Bacchini, Giuseppe Massari)....Pages 295-318 Back Matter ....Pages 319-325
