nextGEMS: entering the era of kilometer-scale Earth system modeling Open
The Next Generation of Earth Modeling Systems (nextGEMS) project aimed to produce multidecadal climate simulations, for the first time, with resolved kilometer-scale (km-scale) processes in the ocean, land, and atmosphere. In only 3 years,…

MultIO: A Framework for Message-Driven Data Routing For Weather and Climate Simulations Open
In numerical weather prediction and high-performance computing, the primary computational bottleneck has gradually evolved from floating-point arithmetic to the throughput of data to and from the storage. This phenomenon is commonly referr…

MultIO: Message-Driven Data Routing for Distributed Earth-System Models Open
Traditionally, in numerical weather prediction, the computational cost of performing floating-point operations (flops) has been the primary concern. However, in the past couple of decades throughput to storage has become a significant bott…
