• Seismic Modeling with Arm Neoverse N1 and AWS Graviton2
    Physics-based three-dimensional numerical simulations are becoming more predictive and are an essential tool for improving the understanding of natural phenomena like seismic wave propagation. These simulations...
  • Assessing AWS Graviton2 for running WRF
    Operational weather forecasting is key to informing many important decisions that are made in agriculture, marine, air transport, environment, military, financial, and other sectors. The WRF (Weather...
  • Evaluation of the NEMO Ocean Model on Arm Neoverse-based AWS Graviton2
    The accuracy of weather and climate predictions is becoming increasingly important. Having the ability to predict extreme events in advance helps us prepare and thus minimize impact. Increasing capability...
  • October 18 - 10^18 - Exascale day, a reason for optimism
    As a long-time member of the HPC community, I have seen a few orders of magnitude performance gains in my career. In the early 90s when the Top500.org list was starting, performance was measured in Gflops...
  • Demonstration of low mach-number CFD modeling with Nalu on AWS Graviton2 M6g instances
    Computational Fluid Dynamic (CFD) simulations are of great importance for the physical process they model with predictive goals as well as the technology research that is developed both numerically and...
