An analytical framework for estimating TCO and exploring data center design space
Hardy, D.; Kleanthous, Marios M.; Sideris, I.; Saidi, A. G.; Ozer, E.; Sazeides, Yiannakis (2013)In this paper, we present EETCO: an estimation and exploration tool that provides qualitative assessment of data center design decisions on Total-Cost-of-Ownership (TCO) and environmental impact. It can capture the ...

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 ...

The performance vulnerability of architectural and non-architectural arrays to permanent faults
Hardy, D.; Sideris, I.; Ladas, N.; Sazeides, Yiannakis (2012)This paper presents a first-order analytical model for determining the performance degradation caused by permanently faulty cells in architectural and non-architectural arrays. We refer to this degradation as the performance ...

Probabilistic WCET estimation in presence of hardware for mitigating the impact of permanent faults
Hardy, D.; Puaut, I.; Sazeides, Yiannakis (Institute of Electrical and Electronics Engineers Inc., 2016)Fine-grained disabling and reconfiguration of hardware elements (functional units, cache blocks) will become economically necessary to recover from permanent failures, whose rate is expected to increase dramatically in the ...

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 ...
