John McCalpin
Biography
John D. McCalpin is a Research Scientist in the High Performance Computing Group and Co-Director of the Advanced Computing Evaluation Laboratory (ACElab) at the Texas Advanced Computing Center (TACC) of the University of Texas at Austin. At TACC, he works on performance analysis and performance modeling in support of both current users and future system acquisitions.
McCalpin joined TACC in 2009 after a twelve-year career in performance analysis and system architecture in the computer industry. This included three years at SGI (performance analysis and optimization on the SGI Origin 2000 and performance lead on the architecture team for the SGI Altix 3000), six years at IBM (performance analysis for HPC, processor and system design for Power4/4+ and Power5/5+, high-level architecture for the Power7-based PERCS Prototype system), and three years at AMD (technology lead for the "Torrenza" program enabling third-party accelerated computing technologies).
Prior to his industrial career, John was an oceanographer (Ph.D., Florida State), spending six years as an assistant professor at the University of Delaware engaged in research and teaching on numerical simulation of the large-scale circulation of the oceans.
In 1991, McCalpin developed the STREAM Benchmark to provide a simple way to measure and report sustainable memory bandwidth, and for 25 years has been an advocate for a multidimensional approach to understanding performance in HPC. In 2015 he was named an "Intel Black Belt Software Developer" in recognition of
his contributions to the Intel Software Developer communities.
