Engility To Provide NOAA With HPC Expertise

Today Engility announced $14 million in task order awards from NOAA’s Geophysical Fluid Dynamics Laboratory. Engility scientists will conduct HPC software development and optimization, help users gain scientific insights, and maintain cyber security controls on NOAA’s R&D High Performance Computing System. These services assist NOAA GFDL in enhancing and advancing their HPC capability to explore and understand climate and weather. “As we saw with Hurricanes Harvey and Irma, a deeper understanding of climate and weather are critical to America’s preparedness, infrastructure and security stance,” said Lynn Dugle, CEO of Engility. “Engility has been at the forefront of leveraging HPC to advance scientific discovery and solve the toughest engineering problems. HPC is, and will continue to be, an area of high interest and value among our customers as they seek to analyze huge and ever-expanding data sets.”

Supercomputers turn the clock back on Storms with “Hindcasting”

Researchers are using supercomputers at LBNL to determine how global climate change has affected the severity of storms and resultant flooding. “The group used the publicly available model, which can be used to forecast future weather, to “hindcast” the conditions that led to the Sept. 9-16, 2013 flooding around Boulder, Colorado.”

Video: Scaling Climate and Weather Forecasting on Sunway TaihuLight

Haohuan Fu from Tsinghua University in China at the PASC17 conference in Lugano. “This talk reports efforts on refactoring and optimizing the climate and weather forecasting programs – CAM and WRF – on Sunway TaihuLight. To map the large code base to the millions of cores on the Sunway system, OpenACC-based refactoring was taken as the major approach, with source-to-source translator tools applied to exploit the most suitable parallelism for the CPE cluster and to fit the intermediate variable into the limited on-chip fast buffer.”

Top Weather and Climate Sites run on DDN Storage

“DDN’s unique ability to handle tough application I/O profiles at speed and scale gives weather and climate organizations the infrastructure they need for rapid, high-fidelity modeling,” said Laura Shepard, senior director of product marketing, DDN. “These capabilities are essential to DDN’s growing base of weather and climate organizations, which are at the forefront of scientific research and advancements – from whole climate atmospheric and oceanic modeling to hurricane and severe weather emergency preparedness to the use of revolutionary, new, high-resolution satellite imagery in weather forecasting.”

Will ECMWF Move Supercomputing to Italy?

Weather and climate simulation services could soon be run in Europe rather than the UK as it was announced that the European Centre for Medium-range Weather Forecasts (ECMWF) is proposing to move its supercomputing capabilities to a new data centre located in Italy.

Dr. Peter Bauer from ECMWF to Keynote ISC 2017

Today ISC 2017 announced that their Tuesday keynote will be delivered by Dr. Peter Bauer from the European Centre for Medium-Range Weather Forecasts (ECMWF). As Deputy Director of the Research Department Center at ECMWF, Dr. Bauer will discuss the computing and data challenges, as well as the current avenues the weather and climate prediction community is taking in preparing for the new computing era.

Supercomputing Sandstorm Forecasts at BSC

“Over the past 15 years, a number of factors have resulted in an increase in the frequency, intensity, and operational impact of sand and dust storms in the Middle East and surrounding areas,” said Bob Richard, vice president, ARINC Direct for Rockwell Collins. “Integrating high-resolution forecast information into our flight and international trip support services will provide safety and performance benefits for business aviation operators in the region.”

UK Met Office Research Simulations Predict European Winter One Year Ahead

In a paper published today in Nature Geoscience, scientists at the Met Office have demonstrated significant advances in predicting up to one year ahead the phases of the North Atlantic Oscillation (NAO), which drives European and North American winter variability. The NAO – a large-scale gradient in air pressure measured between low pressure around Iceland and high pressure around the Azores – is the primary driver of winter climate variability for Europe.

PSyclone Software Eases Weather and Climate Forecasting

“PSyclone was developed for the UK Met Office and is now a part of the build system for Dynamo, the dynamical core currently in development for the Met Office’s ‘next generation’ weather and climate model software. By generating the complex code needed to make use of thousands of processors, PSyclone leaves the Met Office scientists free to concentrate on the science aspects of the model. This means that they will not have to change their code from something that works on a single processing unit (or core) to something that runs on many thousands of cores.”

Exascale Computing – What are the Goals and the Baseline?

Thomas Schulthess presented this talk at the MVAPICH User Group. “Implementation of exascale computing will be different in that application performance is supposed to play a central role in determining the system performance, rather than just considering floating point performance of the high-performance Linpack benchmark. This immediately raises the question as to what the yardstick will be, by which we measure progress towards exascale computing. I will discuss what type of performance improvements will be needed to reach kilometer-scale global climate and weather simulations. This challenge will probably require more than exascale performance.”
