Improving Collective I/O Performance with Machine Learning Supported Auto-tuning

Abstract: Collective Input and output (I/O) is an essential approach in high performance computing (HPC) applications. The achievement of effective collective I/O is a nontrivial job due to the complex interdependencies between the layers of I/O stack. These layers provide the best possible I/O performance through a number of tunable parameters. Sadly, the correct combination of parameters depends on diverse applications and HPC platforms. When a configuration space gets larger, it becomes difficult for humans to monito… Show more

“…The paper first demonstrates the need for a flexible and efficient optimisation approach through a series of experimental benchmarks. This is similar to much existing research which examines how I/O performance can prove challenging in these scenarios [7][8][9][10][11][12]. There are two key contributions outlined in this paper.…”
