NUMA/NEPTUNE Scalability mentioned in Exascale Applications and Software Conference 2016 Plenary Tal

At the Exascale Applications and Software Conference 2016 (April) in Stockholm Sweden (see http://www.epigram-project.eu/easc2016/), Dr. Erland Kallen, the director of ECMWF, gave a talk on the state of the union on numerical weather prediction around the world but also focusing on his center (The European Center for Medium-Range Weather Forecasting). Dr. Kallen gives a great introduction to weather prediction in this Plenary Talk where he mentions that one of the key challenges for the future will be the scalability of the models. At the 34 through 38 minute marks, Dr. Kallen discusses the AVEC report published by the National Oceanographic and Atmospheric Administration (NOAA) and he discusses the scalability results where me mentions, in particular, that the NUMA/NEPTUNE model is the most scalable model in the report. The YouTube video of this presentation can be found here: https://youtu.be/WAqR4aUzpgo.

Since this report was published, we have shown NUMA to scale perfectly up to 3.1 Million MPI threads on the Supercomputer Mira at Argonne National Laboratory. The paper discussing these reports can be found here (click here). For more information on NUMA please go to the NUMA website (click here).
