Research Biography

***Since July 2012 I'm with the Reliability- and Power-Aware Microarchitectures research group at IBM T.J. Watson Research Center leaded by Pradip Bose. This page may contain outdated information. Maybe you might find more updated information here.

Ramon Bertran finished his PhD at the Barcelona Supercomputing Center under the mentorship of Marc Gonzalez. Ramon's research was focused on power-aware computer architecture techniques. Specifically, his thesis was focused on power modelling techniques for multi-core architectures based on Performance Monitoring Counters (PMC). He proposed a novel methodology to produce accurate, decomposable and responsive power models for multicore architectures, overpassing the research challenges introduced by this type of architectures. The methodology was validated on Intel Core 2 Duo and POWER7 platforms as well as on virtualized environments, demonstrating its generality. Moreover, he also proposed a methodology to generate DVFS agnostic power models, capable of predicting the power consumption for any DVFS level.

Besides, he contributed in the areas of power characterization and automatic microbenchmarking. He developed a micro-architecture aware micro-benchmark generator framework to support his work on power characterization. The framework has been used to perform several power-related studies: max-power stressmark generation, inductive noise stressmark generation or automatic instruction EPI (energy per instruction) characterization.

He published several papers in journals and conferences and he did his PhD defense in the Computer Architecture Department of the Universitat Politecnica de Catalunya in December 2014. He is member of the ACM, IEEE and EuroSys organizations since the beginning of his PhD.

Current Research

Currently, he is a Research Staff Member in Reliability and Power-Aware Microarchitecture department at IBM T. J. Watson Research Center. He received the PhD degree on Computer Architecture, Networks and Systems from Polytechnic University of Catalonia (UPC) in 2014.

He is involved in research and development work in the area of power-aware computer architectures and systems. He mainly contributed in the area of power/energy modelling and characterization using automatic microbenchmarking for different IBM processors (p-systems --PowerPC, POWER7, POWER8 and so on, z-systems --mainframes, s390, zEC12, z13 and so on---and BlueGene systems such as BG/Q). He is the lead developer of Microprobe: a micro-architecture aware micro-benchmark generator framework used to support the works on power/performance/reliability characterization.
