Katie Antypas

Katie Antypas is the NERSC Division Deputy and leads the Data Department at NERSC. As the Data Department Head at the National Energy Research Scientific Computing (NERSC) Center, she has oversight of the Data Science Engagement, Data and Analytics Services, Storage Systems, and Infrastructure Services groups.

Katie is the Director of the Hardware and Integration are of the Exascale Computing Project. She is also the co-PI on a ASCR funded research project called ScienceSearch: Enabling Automated Metadata through Machine Learning. Katie has expertise in system architectures, parallel I/O, application performance, and user science requirements.

From 2012-2017, Katie led the NERSC-8 system procurement resulting in the deployment of the Cori system (named after Nobel Laureate Gerty Cori). The Cray XC system features 9300 Intel Knights Landing processors. The Knights Landing processors have over 60 cores with 4 hardware threads each and a 512-bit vector unit width. It is crucial that users can exploit both thread and SIMD vectorization to achieve high performance on Cori. Additionally, the Knights Landing architecture features high bandwidth on-package memory significantly faster than DRAM memory. The Cori system also features the Cray Aries interconnect, 28 PB for a Lustre-based file system, and a "burst buffer" layer of NVRAM that sits between the compute node memory and file system to accelerate I/O. Cori debuted as #6 on the Top500 list.

From 2010 to 2013 Katie was the group leader for User Services at NERSC, a team of consultants who work directly with scientists to help them use apply NERSC resources effectively to their research and to optimize applications.

Prior to becoming the Group Leader of USG, Katie was a consultant in the group from 2006-2010. She was the co-implementation team lead on the Hopper system. Hopper was NERSC's first petaflop system, a Cray XE6 with over 150,000 compute cores which delivered more than 3 million computing hours to scientists each day.

Before coming to NERSC, Katie worked at the ASC Flash Center at the University of Chicago as a parallel programmer developing the FLASH code, a parallel adaptive mesh refinement astrophysics application. She also spent 2 years as a management consultant at Cambridge Strategic Management Group building financial models and conducting market research. She has a Master's degree in Computer Science from the University of Chicago and a Bachelor's degree in Physics from Wellesley College.
