Using differential execution analysis to identify thread interference

Published in IEEE Transactions on Parallel and Distributed Systems, VOL. 30, NO. 12, December 2019, 2019

In this paper, we propose a holistic metric able to pinpoint the blocks of code that suffer interference the most, regardless of the interference cause. Our metric uses performance variation as a universal indicator of interference problems.

DUF: Dynamic Uncore Frequency scaling to reduce power consumption

Published in (HAL), 2019

This paper studies how the uncore frequency can be used as a leverage to improvepower consumption. We propose DUF, a daemon process that dynamically adaptsthe uncore frequency to reduce an application power consumption with a user-definedlimit on performance degradation.

NVCache: A Plug-and-Play NVMM-based I/O Booster for Legacy Systems

Published in 51th IEEE/IFIP International Conference on Dependable Systems and Networks (DSN 21), 2021

This paper introduces NVCache, an approach that uses a non-volatile main memory (NVMM) as a write cache to improve the write performance of legacy applications.
