Title: Dynamic thermal management in chip multiprocessor systems
Author: Liu, Chih-Chun
Abstract: Recently , processor power density has been increasing at an alarming rate result - ing in high on -chip temperature . Higher temperature increases current leakage and causes poor reliability . In our research , we ?rst propose a Predictive Dynamic Ther - mal Management (PDTM ) based on Application -based Thermal Model (ABTM ) and Core -based Thermal Model (CBTM ) in the multicore systems . Based on predicted temperature from ABTM and CBTM , the proposed PDTM can maintain the system temperature below a desired level by moving the running application from the possi - ble overheated core to the future coolest core (migration ) and reducing the processor resources (priority scheduling ) within multicore systems . Furthermore , we present the Thermal Correlative Thermal Management (TCDTM ) , which incorporates three main components : Statistical Workload Estimation (SWE ) , Future Temperature Estima - tion Model (FTEM ) and Temperature -Aware Thread Controller (TATC ) , to model the thermal correlation e ?ect and distinguish the thermal contributions from appli - cations with di ?erent workload behaviors at run time in the CMP systems . The pro - posed PDTM and TCDTM enable the exploration of the tradeo ? between throughput and fairness in temperature -constrained multicore systems .
