| Abstract: | Recently, processor power density has been increasing at an alarming rate resulting in high on-chip temperature. Higher temperature increases current leakage and causes poor reliability. In our research, we first propose a Predictive Dynamic Thermal 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 possible 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 Estimation Model (FTEM) and Temperature-Aware Thread Controller (TATC), to model the thermal correlation effect and distinguish the thermal contributions from applications with different workload behaviors at run time in the CMP systems. The pro- posed PDTM and TCDTM enable the exploration of the tradeoff between throughput and fairness in temperature-constrained multicore systems. |
