TEAPC: Temperature Adaptive Computing in a Real PC
نویسندگان
چکیده
TEAPC is an IBM/Intel-standard PC realization of a CPU temperature-adaptive feedback-control system. The control system adjusts the CPU frequency and/or voltage to maintain a constant set-point temperature. TEAPC dynamically adapts to changing CPU computation loads, as well as any other system phenomenon that affects the CPU temperature. For example, with the specific TEAPC hardware, should the CPU cooling fan fail, the control system detects the increase in CPU temperature and automatically reduces the CPU frequency and voltage to keep the CPU from overheating. In such a circumstance the system continues to operate. All of the adaptation is done dynamically, at runtime, on an unmodified standard operating system (Windows 2000) with a purely software-implemented feedback-control system.

TEAPC: Adaptive Computing and Underclocking in a Real PC
TEAPC is an IBM/Intel-standard PC realization of the TEAtime performance “maximizing” adaptive computing algorithm, giving performance beyond worstcase-specifications. TEAPC goes beyond the TEAtime algorithm by adapting to the current CPU load. It is also the first machine to use extensive underclocking for disaster tolerance, low power consumption and high reliability. This is all done dynamic...

متن کاملImproving the Resilience of Military Hospitals Through Self-Adaptation of Hospital Systems Using Organic Computing
Background and Aim: Among the failures of a disaster, the disruption of the critical infrastructure of the community causes the most damage to society. Therefore, the ability of critical infrastructure such as hospitals to anticipate, absorb, adapt or rapidly recover from a devastating event is essential. The purpose of this study is to design a self-adaptive model for resilient hospital system...
متن کاملProposed Feature Selection for Dynamic Thermal Management in Multicore Systems
Increasing the number of cores in order to the demand of more computing power has led to increasing the processor temperature of a multi-core system. One of the main approaches for reducing temperature is the dynamic thermal management techniques. These methods divided into two classes, reactive and proactive. Proactive methods manage the processor temperature, by forecasting the temperature be...
