Registration is now open for a free Workflows Workshop to be held August 9-10 at multiple institutions across the country. Sponsored by the Blue Waters sustained-petascale computing project, this workshop will provide an overview of workflows and how they can enhance research productivity.
Over at NICS, Scott Gibson writes that researchers are using XSEDE supercomputing resources to simulate the gaseous outflows from black holes known as astrophysical jets. “These jets can affect galaxy formation and evolution by, for example, heating up the surroundings and suppressing star formation, expelling the surrounding gas and thereby reducing the mass supply to the black hole.”
Thanks to a grant from the National Science Foundation, Indiana University is developing an online service that will make it easier for university administrators to understand the importance of funding related to IT systems based at their institutions. The novel functionality will be available as a module for Open XDMoD (XD Metrics on Demand), which was developed by the University at Buffalo Center for Computational Research (CCR).
In this special guest feature, Lance Farrell writes that, in this era of global air travel, NSF-funded researchers are using supercomputers to equip policy makers with the evidence needed to make fast, accurate choices in the event of an epidemic.
In this TACC Podcast, Jorge Salazar looks at how researchers are using the Stampede supercomputer to shed light on the microscale world of colloidal gels — liquids dispersed in a solid medium as a gel. “Colloidal gels are actually soft solids, but we can manipulate their structure to produce ‘on-demand’ transitions from liquid-like to solid-like behavior that can be reversed many times,” Zia said. Zia is an Assistant Professor of Chemical and Biomolecular Engineering at Cornell University.
Over at Science Node, Lance Farrell writes that researchers are using XSEDE supercomputer resources to solve the mysteries of the Old Faithful geyser. “If you look at the distribution of supervolcanoes globally, you’ll find something very interesting. You will see that most if not all of them are sitting close to a subduction zone,” Liu observes. “This close vicinity made me wonder if there were any internal relations between them, and I thought it was necessary and intriguing to further investigate this.”
The summer of 2016 will see a raft of summer schools and other initiatives to train more people in high-performance computing, including efforts to increase the diversity of HPC specialists with a specific program aimed at ethnic minorities. But interested students need to get their applications in now.
Application deadlines are fast approaching for the Blue Waters Graduate Program and the International Summer School on HPC Challenges in Computational Sciences.
Today the Texas Advanced Computing Center (TACC) announced that the Lonestar 5 supercomputer is in full production and is ready to contribute to advancing science across the state of Texas. Managed by TACC, the center’s second petaflop system is primed to be a leading computing resource for the engineering and science research community. “An analysis of strong-scaling on Lonestar 5 shows gains over other comparable resources,” said Scott Waibel, a graduate student in the Department of Geological Sciences at Portland State University. “Lonestar 5 provides the perfect high performance computing resource for our efforts.”
Researchers are using XSEDE compute resources to study how lasers can be used to make useful materials. In this podcast, Dr. Zhigilei discusses the practical applications of zapping surfaces with short laser pulses. Laser ablation, which refers to the ejection of materials from the irradiated target, generates chemical-free nanoparticles that can be used in medical applications, for example.
