Accurately Simulating Energy Consumption of I/O-Intensive Scientific Workflows

Abstract: While distributed computing infrastructures can provide infrastructure-level techniques for managing energy consumption, application-level energy consumption models have also been developed to support energy-efficient scheduling and resource provisioning algorithms.In this work, we analyze the accuracy of a widely-used application-level model that have been developed and used in the context of scientific workflow executions. To this end, we profile two production scientific workflows on a distributed platform … Show more

“…In [40], [41], we have proposed and validated a power consumption model that accounts for CPU utilization, computations that execute on multi-core compute nodes, and I/O operations (including the idle power consumption caused by waiting for these operations to complete). In this work, we leverage this model, to estimate the energy consumption of the execution of large-scale workflows.…”

“…WRENCH has already enabled the development of two simulators of two production application execution frameworks [8], [9] for supporting the study of energy-efficiency for I/O-intensive workflow applications [10], and the study of simulation accuracy and scalability [2]. WRENCH has also gained overseas attention, and received contributions from users in France and Ivory Coast, who are conducting research on workflow scheduling.…”

“…In a recent work [10], we have leveraged the WRENCHenabled Pegasus simulator to investigate the impact of resource utilization and I/O operations on the energy usage, as well as the impact of executing multiple tasks concurrently on multisocket, multi-core compute nodes. Our simulator allowed us to draw direct comparisons between real-world and modeled power and energy consumption.…”
