Exploring DAOS Interfaces and Performance
Nicolau Manubens, Johann Lombardi, Simon D. Smart +4
Distributed Asynchronous Object Store (DAOS) is a novel software-defined object store leveraging Non-Volatile Memory (NVM) devices, designed for high performance. It provides a num…
Reducing the Impact of I/O Contention in Numerical Weather Prediction Workflows at Scale Using DAOS
Nicolau Manubens, Simon D. Smart, Emanuele Danovaro +2
Operational Numerical Weather Prediction (NWP) workflows are highly data-intensive. Data volumes have increased by many orders of magnitude over the last 40 years, and are expected…
DAOS as HPC Storage: Exploring Interfaces
Adrian Jackson, Nicolau Manubens
This work in progress paper outlines research looking at the performance impact of using different storage interfaces to access the high performance object store DAOS. We demonstra…
Evaluating Total Environmental Impact for a Computing Infrastructure
Adrian Jackson, Jon Hays, Alex Owen +3
In this paper we outline the results of a project to evaluate the total climate/carbon impact of a digital research infrastructure for a defined snapshot period. We outline the car…
