Title

[Adjust vCPU Frequency by Workload]

Description

“Tune the frequency of virtual CPUs (vCPUs) dynamically at runtime based on the specific characteristics of software module. This tactic promotes energy efficiency by applying workload-aware frequency scaling rather than relying on default OS policies. The frequency adjustment strategy can be informed by historical execution data and tailored to each module's computational profile, enabling optimal performance-energy trade-offs."

Participant

Scientific software developers

Related software artifact

Scientific software components, runtime frequency scaling policies

Context

High-Performance Computing (HPC) or virtualized environments where the execution of scientific workflows includes heterogeneous modules with diverse computational characteristics. Particularly useful when modules vary in resource demand (e.g., memory-intensive vs. CPU-intensive)

Software feature

CPU frequency scaling, dynamic workload adaptation

Tactic intent

To minimize energy consumption by adapting vCPU frequency to the module’s resource demand characteristics during runtime, rather than relying on static or generalized policies
