DVFaaS: Leveraging DVFS for FaaS Workflows
Achilleas Tzenetopoulos, Dimosthenis Masouros, Dimitrios Soudris, Sotirios Xydis · IEEE Computer Architecture Letters · 2023
In this letter, we proposeDVFaaS, a per-core DVFS framework that utilizes control systems theory to assignjust-enoughfrequency for the purpose of addressing the QoS requirements on serverless workflows comprising unseen functions.DVFaaSexploits the intermittent nature of serverless workflows, which enables staged control on distinguishable functions, which jointly contribute to the end-to-end latency. Our results show thatDVFaaSconsiderably outperforms related work, reducing power consumption by up to 22%, with 2x fewer QoS violations.
