A Comprehensive Timing, Power, Thermal, and Reliability Model for Exascale Node Architectures
ثبت نشده
چکیده
In modern processors, the interactions between performance, power, thermal, and reliability are complex. Neglecting one aspect, such as reliability, might lead to unrealistically optimistic evaluations of the other aspects due to the (implicit) assumption on non-faulty devices [15]. The sheer size and the compute, power, and mean-time-to-intervention (MTTI) requirements of an exascale system further increase the need to model the dynamic interactions between all four aspects [5]. Hence a detailed analysis to determine the capability of a processing node must precede extrapolations to the datacenter using other methodologies [6].

Reliability and Performance Evaluation of Fault-aware Routing Methods for Network-on-Chip Architectures (RESEARCH NOTE)
Nowadays, faults and failures are increasing especially in complex systems such as Network-on-Chip (NoC) based Systems-on-a-Chip due to the increasing susceptibility and decreasing feature sizes. On the other hand, fault-tolerant routing algorithms have an evident effect on tolerating permanent faults and improving the reliability of a Network-on-Chip based system. This paper presents reliabili...
