What’s cooking at CNI?
CNI PhD fellow, Moonmoon Mohanty, has co-authored a conference paper titled "Energy-minimizing workload splitting and frequency selection for guaranteed performance over heterogeneous cores". She will present the same work at the 15th ACM International Conference on Future and Sustainable Energy Systems, which will be held in Singapore from June 4 - 7, 2024. Read more...
Heterogeneous computing involves CPU architectures that support more than one core type, and it aims to achieve energy efficiency while meeting the performance guarantees. This aim can be achieved by the operating system or the on-chip driver by exploiting the differential power-performance trade-off that heterogeneous cores offer. In their work, they have characterised the power-performance trade-off for an Intel CPU with heterogeneous cores and provided a mathematical framework to study heterogeneous computing. In particular, a probabilistic workload split and operating frequency for all active cores that allow workload execution with minimal carbon emissions is provided. The analytical findings are supported by experimental evaluations for a few representative workloads. As compared to the default Linux frequency governors, their scheme can reduce the energy-delay product by up to 80%.
