I am a researcher at the Computer Science department of the Barcelona Supercomputing Center (BSC) since 2006. My research interest includes load balancing, parallel programming, performance analysis, and optimization.I co-lead the Best Practices for Performance and Productivity (BePPP) group at BSC. BePPP aims to be the bridge between scientific domain researchers and computer scientists. Promoting best practices for programmers to productively (re)structure their codes in ways that can result in high efficiency and portability. And capture the fundamental co-design input forwarding it to the appropriate system software and architecture team to target their developments in the most useful direction.
