Speaker: Ricardo Macedo, Research Assistant, Institute for Systems and Computer Engineering, Technology and Science (INESC TEC) and University of Minho

Moderator: Todd Evans, Researcher Associate, Texas Advanced Computing Center (TACC)

HPC infrastructures are long thought as computational powerhouses that enable scientists to conduct massively parallel jobs. However, with the advent of new data-intensive workloads from both scientific and deep learning jobs, the storage performance has become a pressing concern in these infrastructures, due to high levels of performance variability and I/O contention generated by multiple applications executing concurrently. In this webinar, we discuss how to build portable and generally applicable Software-Defined Storage data planes tailored for the requirements of data-centric applications running on modern HPC infrastructures. We demonstrate how to improve I/O performance and manage I/O interference of HPC jobs with none to minor code changes to applications and HPC storage backends.

About the speaker:

Ricardo Macedo is a researcher at HASLab INESC TEC and a 4th year PhD student at University of Minho, advised by Prof. João Paulo and Prof. José Pereira. His research interests include local and distributed storage systems, with particular focus in Software-Defined Storage, programmable and distributed storage, and kernel-/user-space storage technologies. Currently, Ricardo is working on a Software-Defined Storage data plane framework for enforcing end-to-end performance policies in complex storage infrastructures.
