BlackOut: Enabling fine-grained power gating of buffers in Network-on-Chip routers
Zoni, D.; Canidio, A.; Fornaciari, W.; Englezakis, Panayiotis; Nicopoulos, Chrysostomos A.; Sazeides, Yiannakis (2017)The Network-on-Chip (NoC) router buffers play an instrumental role in the performance of both the interconnection fabric and the entire multi-/many-core system. Nevertheless, the buffers also constitute the major leakage ...

HARPA: Solutions for dependable performance under physically induced performance variability
Rodopoulos, Dimitrios; Corbetta, S.; Massari, Giuseppe; Libutti, S.; Catthoor, F.; Sazeides, Yiannakis; Nicopoulos, Chrysostomos A.; Portero, Antoni; Cappe, E.; Vavrík, R.; Vondrák, V.; Soudris, Dimitrios J.; Sassi, F.; Fritsch, A.; Fornaciari, W. (Institute of Electrical and Electronics Engineers Inc., 2015)Transistor miniaturization, combined with the dawn of novel switching semiconductor structures, calls for careful examination of the variability and aging of the computer fabric. Time-zero and time-dependent phenomena need ...

NoCAlert: An on-line and real-time fault detection mechanism for network-on-chip architectures
Prodromou, Andreas; Panteli, Andreas; Nicopoulos, Chrysostomos A.; Sazeides, Yiannakis (2012)The widespread proliferation of the Chip Multi-Processor (CMP) paradigm has cemented the criticality of the on-chip interconnection fabric. The Network-on-Chip (NoC) is becoming increasingly susceptible to emerging reliability ...

An online and real-time fault detection and localization mechanism for network-on-chip architectures
Chrysanthou, Kypros; Englezakis, Panayiotis; Prodromou, Andreas; Panteli, Andreas; Nicopoulos, Chrysostomos A.; Sazeides, Yiannakis; Dimitrakopoulos, Giorgos N. (2016)Networks-on-Chip (NoC) are becoming increasingly susceptible to emerging reliability threats. The need to detect and localize the occurrence of faults at runtime is steadily becoming imperative. In this work, we propose ...

Optimizing data-center tco with scale-out processors
Grot, B.; Hardy, D.; Lotfi-Kamran, P.; Falsafi, B.; Nicopoulos, Chrysostomos A.; Sazeides, Yiannakis (2012)Performance and total cost of ownership (TCO) are key optimization metrics in large-scale data centers. According to these metrics, data centers designed with conventional server processors are inefficient. Recently ...

Thermal characterization of cloud workloads on a power-efficient server-on-chip
Milojevic, D.; Idgunji, S.; Jevdjic, D.; Ozer, E.; Lotfi-Kamran, P.; Panteli, Andreas; Prodromou, Andreas; Nicopoulos, Chrysostomos A.; Hardy, D.; Falsari, B.; Sazeides, Yiannakis (2012)We propose a power-efficient many-core server-on-chip system with 3D-stacked Wide I/O DRAM targeting cloud workloads in datacenters. The integration of 3D-stacked Wide I/O DRAM on top of a logic die increases available ...

Toward multi-layer holistic evaluation of system designs
Kleanthous, Marios M.; Sazeides, Yiannakis; Ozer, E.; Nicopoulos, Chrysostomos A.; Nikolaou, Panagiota; Hadjilambrou, Zacharias (2016)The common practice for quantifying the benefit(s) of design-time architectural choices of server processors is often limited to the chip- or server-level. This quantification process invariably entails the use of salient ...
