Science Highlights
Blue Whirl Flame Structure Revealed with Supercomputers
XSEDE-allocated Stampede2 simulates 3D structure of vortex breakdown with combustion
Lightning struck a bourbon warehouse, setting fire to a cache of 800,000 gallons of liquor in the Bardstown countryside of Kentucky in 2003. Some of it spilled into a nearby creek, spawning a massive fire tornado, or "bourbonado," as reported locally. Aerial video of it inspired scientists to investigate fire whirls, tornados of fire, as something promising for oil spill remediation because the alcohol burned with relatively little soot.
Their fire whirl investigations in the lab led them to find something that astonished them. The chaotic and dangerous fire whirl transformed into a tame and clean burning flame they call a "blue whirl." One of its discoverers is now on a science team using supercomputers allocated by XSEDE to reveal the structure of the blue whirl, a new type of flame that consists of four separate flames. The scientists hope blue whirls can one day be used to burn fuels more cleanly.
Blue whirls are a swirling flame phenomenon that evolves from a chaotic fire whirl and burns with nearly soot-free combustion. Supercomputer simulations have revealed the flame structure and flow structure of the blue whirl. (A) Volume rendering of the heat release rate from the numerical simulations.

Online Supply Chain Tool Available to Authorities, Public Thanks to XSEDE Resources
Website for analyzing critical good, supply vulnerabilities developed by Bridges, other XSEDE systems
Supply chains of goods like food, fuel, and water have created wealth and greatly reduced human hunger. But they also bring with them vulnerabilities, when supplies are disrupted by natural disasters, human conflicts, or sudden demand. Using the XSEDE-allocated Bridges supercomputing platform at the Pittsburgh Supercomputing Center (PSC), scientists at Northern Arizona University (NAU) are expanding their online tool for studying supply chains and are rolling out a program for sharing it with other researchers, governments, and members of the public.

High-Performance Computing Aids in Predicting Oil Dispersal During Spills
Supercomputer simulations detail oil's behavior during crossflow waves
According to the National Oceanic and Atmospheric Administration (NOAA), thousands of oil spills occur each year in the United States. Although the majority of incidents involve less than one barrel, the spills have wreaked economic and environmental devastation for decades. To better understand the fate of oil droplets for effective countermeasures, researchers recently created simulations using XSEDE-allocated supercomputers, including Comet at the San Diego Supercomputer Center (SDSC) at UC San Diego and Bridges at the Pittsburgh Supercomputing Center (PSC).

Program Announcements
XSEDE Cyberinfrastructure Integration Updates
A new Comprehensive XSEDE Software Discovery service is now available on the Research Software that significantly enhances the ability to find and use software, services, cloud images, cluster toolkits, and public container registries and XSEDE's InCommon Identity Provider has been migrated and updated to Shibboleth IdP V4.
New XSEDE Highlights Book Available!
The annual XSEDE Highlights book is here! In this publication, we provide a select set of research accomplishments enabled, in part, by XSEDE. 
XSEDE Allocations Lead to Multiple HPCWire Awards
Multiple research projects carried out on XSEDE allocations were recognized via the HPCWire Editors' and Readers' Choice Awards at the Supercomputing (SC) 20 conference this year, including research allocated via the COVID-19 HPC Consortium, whose allocations process is administered by XRAS. Congratulations to all partner institutions involved with these projects. The full list of award winners may be found through the link below.
