2020 MultiCore 10 Workshop

Sep. 28 to Oct. 2, 2020

5:00 pm – 10:00 am MDT


MultiCore 10 was held virtually the week of September 28, 2020 and was hosted by the National Center for Atmospheric Research (NCAR) which is located in Boulder, Colorado, USA.


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.
