1、introduction

• this paper proposes an algorithm, the Pareto-efficient Stepwise Frequency Selection Algorithm (PSFS), to provision CPU frequencies for a predefined number of CPU resources that aims to find cost-efficient, Pareto-optimal solutions for different execution time and cost trade-offs
• In this paper, the proposed approach is extended to return a Pareto set that meets different cost-performance tradeoffs, something that allows the user to select CPU frequency configurations according to different requirements.

4、 Algorithm description

• Pareto-efficient stepwise frequency selection (PSFS) algorithm.
• Cost-based stepwise frequency selection from heterogeneous resources (CSFS-H) algorithm.

6、 Conclusion

This paper proposed an approach to select Pareto-efficient CPU frequency configurations for the execution of scientific workflows on a selected number of cloud resources. The main idea has been to prune the search space by carefully selecting a small set of initial CPU frequencies to build an initial Pareto front, which a subsequent algorithm attempts to improve.
