Using surrogate-based modeling to predict optimal I/O parameters of applications at the extreme scale

Published in 20th IEEE International Conference on Parallel and Distributed Systems (ICPADS), 2014

We adopt and adapt an engineering method called surrogate-based modeling to efficiently search for the optimal I/O parameter values and accurately predict the associated I/O times at the extreme scale.

Performance impact of I/O on QMCPack simulations at the petascale and beyond

Published in IEEE 16th International Conference on Computational Science and Engineering, 2013

In this paper, we work to increase the granularity of the I/O in QMCPack simulations without increasing the I/O associated overhead or compromising the scalability of the simulations.
