Machine Learning: Improved predictions for time-to-solution of materials science simulations
The accurate prediction of the time-to-solution required by massively parallel scientific codes is a key goal in HPC. It allows scientists to better program and allocate their computational tasks, and benefits environmental sustainability since energy waste due to sub-optimal execution parameters could be easily detected. Such prediction is however especially challenging for hybrid and complex architectures. An important step in this direction has been obtained with machine learning techniques for DFT-based material science codes. The results by Pittino et al, presented at PASC 19, show how accurate predictions obtained with machine learning approaches can outperform parametrized analytical performance models made by domain experts.
