Research Biography

Ramon Bertran is a PhD student at the Barcelona Supercomputing Center under the mentorship of Marc Gonzalez. Ramon Bertran's research is focused on power and performance modelling techniques for multi-core architectures based on Performance Monitoring Counters (PMC). He has contributed with a novel methodology to produce accurate, decomposable, responsive (in overall, more informative) power and performance models, and overpassing the new research challenges introduced by recent multicore architectures. The methodology has been validated on virtualized environments and with the Dynamic Voltage and Frequency Scaling (DVFS) mechanism proposing also DVFS agnostics power models, capable of predicting the power consumption for any DVFS level. He has published several papers in journals and conferences and he is preparing his PhD defense in the Computer Architecture Department of the Universitat Politècnica de Catalunya.
