Weather and Climate

Weather and Climate

Weather and climate centers worldwide rely on the power of high-performance computing (HPC), and Altair keeps HPC running reliably and efficiently. Because modeling the Earth’s weather and climate is a challenge, it requires powerful HPC systems and software that can orchestrate the most complex workloads. Fields such as climate modeling and numerical weather forecasting have global economic and social impact.

PBS Professional and the Cylc Workflow Engine

Cylc is an open-source workflow engine for cycling systems that handles a range of workflow complexities. It automatically executes tasks according to detailed schedules and dependencies, and it’s especially useful in areas such as weather and climate modeling, numerical weather prediction, physics simulation, and data processing.

Cylc has become a popular choice at major weather and climate centers around the world — and now it’s a key tool at Australia's Bureau of Meteorology. Cylc was originally developed for operational environmental forecasting at NIWA, the National Institute of Water and Atmospheric Research in New Zealand, and now it’s an open-source collaboration between NIWA, the Met Office (UK), the Center of Excellence for Weather and Climate Simulation in Europe (ESiWACE), the Bureau of Meteorology, and other contributors.

Altair, NIWA, and the Bureau of Meteorology developed a production environment for monitoring the performance of many Cylc workflows along with Altair® PBS Professional®, our industry-leading workload manager and job scheduler for HPC and cloud environments. Altair provides commercial support for the community-based Cylc workflow engine.

More About the Collaboration

The Altair Weather Solution

Altair’s weather solution is built on the PBS Professional workload manager for HPC and cloud environments, combined with the Cylc workflow engine. The solution lets users monitor HPC hardware, Cylc suites, and PBS Professional jobs, and it provides clear and concise status reporting. Purpose-built for the complex workloads of climate modeling and prediction, the Altair weather solution was designed to be modular, comes ready for easy, out-of-the-box deployment and includes:

  • Message Viewer: View into Cylc and PBS Professional messages
  • Event Inspector: Insight into system events
  • Message Modifier: For development and support
  • Schedule Prediction Tool: Visual representation of the workflow schedule
