Diagnosing applications' I/O behavior through system call observability
Tânia Esteves, Ricardo Macedo, Rui Oliveira +1
We present DIO, a generic tool for observing inefficient and erroneous I/O interactions between applications and in-kernel storage systems that lead to performance, dependability,…
PADLL: Taming Metadata-intensive HPC Jobs Through Dynamic, Application-agnostic QoS Control
Ricardo Macedo, Mariana Miranda, Yusuke Tanimura +6
Modern I/O applications that run on HPC infrastructures are increasingly becoming read and metadata intensive. However, having multiple concurrent applications submitting large amo…
PAIO: A Software-Defined Storage Data Plane Framework
Ricardo Macedo, Yusuke Tanimura, Jason Haga +3
We propose PAIO, the first general-purpose framework that enables system designers to build custom-made Software-Defined Storage (SDS) data plane stages. It provides the means to i…
