Supercomputing Spotlights is a new webinar series featuring short 
presentations that highlight the impact and successes of 
high-performance computing (HPC) throughout our world. Presentations, 
emphasizing achievements and opportunities in HPC, are intended for the 
broad international community, especially students and newcomers to the 
field. Supercomputing Spotlights is an outreach initiative of 
SIAG/Supercomputing (https://urldefense.us/v3/__https://siag-sc.org__;!!G_uCfscf7eWS!bs80uo_YmGleV2pAEroEO0RcXJNuh3YQBNbOBiK36fIs0rPNUTPxchRGpj_kATUPOkWQpdKivlAj57FHreT1Dc9x6lqMU1w$ ) …  Join us!

Abstract: The duration and scale of the exascale computing project (ECP) 
provided a unique opportunity to advance computational science in a wide 
variety of application areas.   The project lasted seven years and 
funded over one thousand researchers to develop 24 applications, over 70 
software products, and deploy them on the exascale computers when they 
were first deployed at the DOE facilities.    This results in many 
notable outcomes including:   the first integrated HPC software stack 
comprising over 100 libraries, performance portable applications 
refactored for accelerator-based computing architectures, and a new 
generation of computational scientists exposed to state-of-the-art 
techniques.  In this talk we will give an overview of the exascale 
computing project and highlight key legacy outcomes that will impact the 
computational science community for years to come.   We will also 
discuss the major outcomes and lessons learned in creating the exascale 
ecosystem; particularly in algorithm design and implementation for 
accelerator-based compute nodes, performance portability across a range 
of platforms, fostering strong collaborations across multidisciplinary 
teams, and managing and measuring the success of a computational science 
project of this scale.

Bio: Lori Diachin is the Director for the U.S. Department of Energy's 
Exascale Computing Project (ECP). ECP is a collaborative Department of 
Energy effort supported by both the National Nuclear Security 
Administration and the Office of Science to accelerate the delivery of a 
capable exascale computing ecosystem for breakthroughs in scientific 
discovery, energy assurance, economic competitiveness, and national 
security.  In her role as the Director, Lori is responsible for setting 
the strategic direction for ECP and ensuring that the project has an 
impactful and executable plan that delivers on its goals and objectives.

Lori is also serving as the Principal Deputy Associate Director (PDAD) 
in the Computing Directorate at Lawrence Livermore National Laboratory. 
The Computing Directorate has approximately 1400 staff serving the needs 
of the laboratory in areas ranging from high performance computing, 
computing sciences for the missions of LLNL, and information technology 
for business and workforce enablement. In this role, Lori serves as a 
senior-level advisor to the Computing Associate Director and to division 
leaders and institute directors on strategies to develop and sustain 
critical computer and computational capabilities.

Lori Diachin has over 30 years experience in high performance computing 
and applied mathematics research where her areas of expertise include 
mesh quality improvement, mesh component software, numerical methods, 
and parallel computing. She is the co-author of over 50 technical 
journal articles, book chapters, and conference proceeding articles in 
these areas. Before joining LLNL, Lori was a computer scientist at 
Argonne National Laboratory and a Member of the Technical Staff at 
Sandia National Laboratory. Lori received her Bachelor's degree in 
Mathematics from Edinboro University of Pennsylvania in 1988 and her 
Ph.D. in Applied Mathematics from University of Virginia in 1992. She 
joined Lawrence Livermore National Laboratory in 2003.
