2019 MultiCore 9 Workshop


2019 MultiCore 9 Workshop

September 25th & 26th, 2019, at the National Center for Atmospheric Research (NCAR) Mesa Lab in Boulder, Colorado

******If you would like to join remotely, please use the following Webcast link: https://ucarconnect.ucar.edu/  (you will need to click on "UCAR Live" tab at the top) 


The purpose of this workshop is to provide a forum for open discussion to better understand the application of new high performance computing technologies for the next generation of weather, climate, and earth-system models. The new generation of High Performance Computer (HPC) architectures has diverse heterogeneous architectures and they present significant challenges to the community working on these models.


Workshop Goals

The workshop primary goals are:

  • Provide a forum to present experiences and lessons learned from development of weather and climate models on these platforms.
  • Create a community of developers to collect and enunciate requirements for next-generation HPC programming models, tools, systems, and hardware.
  • Exchange information and ideas on topics including:
  • Techniques for programming, performance analysis and optimization and I/O strategies on these platforms.
  • Language, library, and directive based approaches for programming earth system applications. 
  • Achieving performance portability across diverse heterogeneous architectures
  • Handling of multiple or heterogeneous memory on both CPU and GPU 
  • Use of mixed-precision 
  • Utilization of non-volatile on-node storage for complex workflows and data analysis
  • Advancements in machine and deep learning techniques for physics code surrogates, data analysis and assimilation.
  • Entrain student and early career computational scientists into HPC for earth system applications.


Keynote Speakers 



The ECMWF Scalability Programme - Progress and Plans- Dr. Peter Bauer

Dr Peter Bauer is the Deputy Director of the Research Department at ECMWF and heads the ECMWF Scalability Programme. He obtained his PhD degree in meteorology from the University in Hamburg, Germany. During his career, he was awarded post-doctoral and research fellowships working at NOAA and NASA in the US and IPSL in France. He is an international fellow of the German Helmholtz Society. He led a research team on satellite meteorology at DLR in Germany before joining ECMWF in 2000. He has been a member of advisory committees for national weather services, the World Meteorological Organization and European space agencies. He is coordinating the FET-HPC projects ESCAPE and ESCAPE-2, and the recent ExtremeEarth proposal for European Flagships.


Accelerating Earth System Models with machine learningKelly Kochanski 

Kelly Kochanski is a doctoral candidate at the University of Colorado Boulder, where she holds a Computational Science Graduate Fellowship from the Department of Energy. She conducts research on subgrid scale snow features both in the field, through the CU Institute for Arctic and Alpine Research, and on high-performance computers at Lawrence Livermore National Laboratory. Translating science between those two realms has led her to focus on building Earth system models that are both computationally efficient and true to scientific observations. She is the climate science lead for Climate Change AI, an initiative by top thinkers in AI to identify high-impact ways to use machine learning to tackle climate change.


Workshop Program

The workshop will consist of a limited number of presentations by the two invited speakers plus a series of 20-25 minute presentations of selected attendee submissions and a poster session. The link to the workshop program is HERE.



Registration is open until September 20th or until there are 80 confirmed registrants. To register and submit an abstract, please complete the form by clicking HERE

We hope to provide travel support of up to $1,500 for a limited number of out-of-town students/early-career presenters. Awards will be based on availability of funds and merit of the submission as determined by the program committee. Travel must be arranged through NCAR. Indicate your interest by completing the Travel Support Request form, the link to which is found on the registration form.



The workshop will be hosted by the National Center for Atmospheric Research (NCAR) and held in the Mesa Laboratory, 1850 Table Mesa Drive, Boulder, CO 80305, September 25th & 26th, 2019. Lunch both days will be the NCAR Cafe.  Please note the cafe can only accept cash payments. NCAR does have an ATM machine onsite if needed.



The Hilton Garden Inn is the official conference hotel, located at 2701 Canyon Boulevard in Boulder. The room block rate is available for the dates of September 23-26, 2019. Conference rate is $131/night. Check-in time is 3:00pm, check-out time 11:00am on departure day. For reservations, please use this link Hilton Garden Inn - 2019 MultiCore 9 Workshop or call (855)-437-4231 or 303-443-2600 ex 0, where Maryann is happy to assist (ask for the NCAR 2019 MultiCore 9 Workshop room block). Room block rate is available until Friday September 13, 2019. 


Transportation to Mesa Laboratory

Out of town guests should plan to arrange their own transportation (rental car, bus, Uber/Lyft, etc.) to the Mesa Laboratory as the UCAR shuttle service is reserved for employees only.
