The status of the testing of ECP applications on the Summit system at Oak Ridge National Laboratory (ORNL) and the success and impact of the co-design centers are among the subjects of an audio update from Andrew Siegel, director of ECP’s Application Development (AD) research focus area.
- We’re already seeing very good early results on Summit for a few applications. Summit is in the early stages of testing at ORNL, and ECP applications for nuclear energy, computational cosmology, and fusion have run large test problems with excellent results. A scaled-down version of Summit, summit_dev, is available more broadly on a per-request basis.
- The co-design center approach has been very successful and has had significant impact on application projects. Adaptive mesh refinement in AMRex (Co-Design Center for Block-Structured AMR) and higher-order unstructured meshes in CEED (Center for Efficient Exascale Discretizations) are being broadly adopted and deeply integrated in application projects. CODAR (Co-Design Center for Online Data Analysis and Reduction) is developing data compression tools for which there is great interest across a wide range of applications, and the COPA (Co-Design Center for Particle Applications) project has been doing work on FFTs (fast Fourier transforms) that have led to a new stand-alone effort in building a more general exascale FFT effort.
- Co-design success and the use of machine learning across projects has led us to explore standing up a new machine learning co-design center, possibly as early as 2018. Plans are being developed and will be presented at the end of the month.
