Weather and Climate

Helping to improve the pace and precision of forecasting

Numerical Weather Prediction of today's weather forecasts and climate prediction require massive use of high performance computing. Supercomputers used for weather forecasting are amongst the largest in the world.

The leading centers of research - including NOAA, ECMWF, UK Met Office, Meteo France and Deutscher Wetterdienst - rely on Allinea's tools to ensure that they deliver the information that we need to live our lives safely.

Accurate and timely forecasting requires software that is correct and efficient - and Allinea's development tools are at the heart of the field.

Forecasting software is continuously developed by weather and climate centers and consortia and is deployed on the increasingly powerful supercomputers. Larger ensembles are necessary to increase confidence in forecasts - which mean running more simulations.  Each simulation run must be efficient and well optimized. Finer-grain grids for more precise predictions mean greater scale - necessitating development tools and performance tools that can handle more processes simultaneously.

We needed a solution that could not only handle our very complicated code, but that could be used in a wide range of scales.

The tools enable centers to solve difficult bugs quickly and to reduce the time it takes for software to produce a forecast. The scalability of Allinea Forge provides the weather community with development tools that are able to handle the size of today's systems.  Alinea's tools integrate cleanly with the complex workflow of scientists - and can handle the massive codebases of both legacy and new software.

Developing for Weather and Climate

From winter blizzards bearing down on the east coast of the United States, to floods in Argentina and droughts in Brazil, severe weather conditions can leave devastation in their wake. While the predictability – or seemingly lack thereof – of weather patterns is a headline-grabbing topic, great strides are being made to increase the fidelity and range of forecasts on both a local level and global scale.

Tied together within the same community, the fields of weather forecasting and climate modelling may differ in both focus and approach, but the fundamental goal of developing more accurate predictions through the use of higher fidelity modelling and simulation tools remains the same. And critical to this goal is high-performance computing (HPC).

The right debugger can save everyone quite a bit of time, and that’s what we’re really trying to do with Allinea DDT – improve the time to solution for a development or investigation of a scientific problem.

DKRZ - The German Climate Computing Center

At DKRZ, Germany's leading center for climate research, researchers produce simulations to model extremely complex scenarios. Reproducible and accurate science means high quality software is essential.

When software problems arise, DKRZ, relies on Allinea DDT.  Climate scientists need to focus on their urgent research and have no time to waste learning difficult tools for software debugging.

Allinea DDT can pinpoint software problems on massive supercomputers in minutes instead of days.

Allinea DDT is a real time-saver. The problem was particularly difficult to understand because it happened only in this context on one particular task. With Allinea DDT, it only took a few minutes to see this bug. Once we knew the location, it was very easy to fix.
