Abstract :
This paper presents a task migration algorithm for dynamic thermal management of Simultaneous Multi-Threading (SMT) multi-core processors. The unique features of this algorithm include: 1) considering SMT capability of processors for dynamic thermal management via task scheduling, 2) using adaptive task migration threshold, and 3) considering cores physical features. This algorithm is evaluated on a commercial SMT quad-core processor. The experimental results indicate that our technique can significantly decrease the average and peak temperature compared to Linux standard scheduler, and two well-known thermal management techniques.
