With the increasing complexity of parallel applications, which require more computing power, energy consumption has become an important issue. The power consumption of high-performance computing (HPC) systems is expected to significantly grow (up to 100 MW) in the next years (Dutot et al., Towards energy budget control in HPC. In: IEEE/ACM International Symposium on Cluster, Cloud and Grid Computing, pp. 381–390. IEEE, Piscataway, 2017). Moreover, while general-purpose processors are being pulled back by the limits of the thermal design power (TDP), most of the embedded devices are mobile and heavily dependent on battery (e.g., smartphones and tablets). Therefore, the primary objective when designing and executing parallel applications is not to merely improve performance but to do so with minimal impact on energy consumption. |
