September 2019 | Science Highlights, Announcements & Upcoming Events
XSEDE helps the nation's most creative minds discover breakthroughs and solutions for some of the world's greatest scientific challenges. Through free, customized access to the National Science Foundation's advanced digital resources, consulting, training, and mentorship opportunities, XSEDE enables you to Discover More. Get started here.
Science Highlights
Turbulence Meets a Shock
Stampede2 , ECSS help simulate shock turbulence interactions
This may come as a shock, if you're moving fast enough. The shock being shock waves. Far out in the cosmos, a collapsing star generates shock waves from particles racing near the speed of light as the star goes supernova. Scientists are using supercomputers allocated through XSEDE, including Stampede2 at the Texas Advanced Computing Center (TACC), to get a better understanding of turbulent flows that interact with shock waves. This understanding could help develop supersonic and hypersonic aircraft, more efficient engine ignition, as well as probe the mysteries of supernova explosions, star formation, and more.
A new theoretical framework was developed and tested using the Stampede2 supercomputer to understand turbulent jumps of mean thermodynamic quantities, shock structure and amplification factors. Turbulence comes in from the left in this image, hitting the shock, and leaving the domain from the right. This three-dimensional picture shows the structure of enstrophy and colored by local Mach number with the shock at gray. Credit: Chang-Hsin Chen, TAMU.
Magnetic Fields with a Laser Beam
XSEDE-allocated supercomputers aid in novel simulations of x-ray laser research
While intense magnetic fields are naturally generated by neutron stars, researchers have been striving to achieve similar results in the laboratory for many years. Tao Wang, a University of California San Diego mechanical and aerospace engineering graduate student, recently demonstrated how an extremely strong magnetic field, similar to that on the surface of a neutron star, can be not only generated but also detected using an x-ray laser inside a solid material. Wang carried out his research with the help of simulations conducted on the Comet supercomputer at the San Diego Supercomputer Center ( SDSC ) as well as Stampede1 and Stampede2 at the Texas Advanced Computing Center ( TACC ). All resources were allocated via XSEDE.
This Comet -generated simulation illustrates how an intense laser pulse renders a dense material relativistically transparent, thereby allowing it to propagat e the material is penetrated and the laser pushes the electrons to form an extremely strong magnetic field. The strength is comparable to that on a neutron star's surface, which is at least 100 million times stronger than the Earth's magnetic field and a thousand times stronger than the field of superconducting magnets. Credit: Tao Wang, Department of Mechanical and Aerospace Engineering, and the Center for Energy Research, UC San Diego.
Program Announcements
XSEDE Cyberinfrastructure Integration (XCI) updates
The XSEDE Cyberinfrastructure Integration (XCI) team has released a new REST API that enables a gateway to directly report the user associated with a job that is running under a gateway account for XSEDE accounting purposes. Gateways are strongly advised to switch to the new method of reporting these attributes as the older method will be decommissioned after Nov 30, 2019. 
Apply by Nov. 1 for Spring 2020 XSEDE EMPOWER internships
Do you know an undergraduate interested in computation, conducting their own research, and making connections within our community? Tell them about  XSEDE EMPOWER  ( E xpert  M entoring  P roducing  O pportunities for  W ork,  E ducation, and  R esearch), an internship program where undergraduates have the chance to participate in actual XSEDE activities, like computational research and education in all fields of study, data analytics research and education, networking, system maintenance and support, and visualization. Undergraduate students at any U.S. degree-granting institution are welcome to apply. No prior experience necessary. EMPOWER is also accepting applications for those who would like to serve as mentors.  The deadline to apply for Spring 2020 internships and mentorships is November 1, 2019.
Check out this video to learn more about XSEDE EMPOWER and what two recent interns have to say about the program.
Community Announcements
