- The chip multiprocessor (CMP) thermal issue impacting the system reliability and cooling cost has become a limiting factor for chip scaling and attracted growing attentions in the dark-silicon era. We propose a thermal-aware thread-to-core mapping method for CMPs under the dark-silicon constraint. We first propose a high-level spatial-temporal information-based thermal model to capture the relationship between the mapping result and the system thermal distribution. Then, we develop a thermal-aware mapping algorithm, which can automatically assign threads to proper cores based on the proposed model. Finally, we evaluate our method through simulations. Compared with three other mapping methods, namely, random, network-on-chip (NoC)-sprinting and round-robin, our thermal-priority design decreases the peak temperature by up to 4.31 K while showing good communication performance (34.7% of improvement against random and 50.3% against NoC sprinting, and only 6.3% of degradation against round robin); and our latency-priority design achieves the best communication performance with an improvement up to 62.6% and a satisfactory thermal profile.
