Science Highlights
Star Crash
Artificial intelligence on XSEDE systems is key to speeding simulations of neutron star mergers
Collisions between neutron stars involve some of the most extreme physics in the Universe. The intense effects of vast matter density and magnetic fields make them computation-hungry to simulate. A team from the National Center for Supercomputing Applications (NCSA) used artificial intelligence on the advanced graphics-processing-unit (GPU) nodes of the XSEDE-allocated supercomputers Bridges at the Pittsburgh Supercomputing Center (PSC) as well as Stampede2 at the Texas Advanced Computing Center (TACC) to obtain a correction factor that will allow much faster, less detailed simulations to produce accurate predictions of these mergers.

The intense magnetic fields accompanying movement of matter from neutron-stars past each other causes increasingly complicated turbulence that is computationally expensive with standard simulation methods. Here, a deep learning AI provides a simulation of this process at a fraction of the computing time.
Every Calculation Stabs
XSEDE and other resources enable team to span time scales in simulating dagger-like microbe-killing molecule
Medical science is in a race to develop new and better antimicrobial agents to address infection and other human diseases. One promising example of such agents is the beta-defensins. These naturally occurring molecules stab microbes' outer membranes, dagger-like, causing their contents to spill out. A scientist at Tennessee Tech University used the XSEDE-allocated Bridges platform at PSC, as well as the D .E. Shaw Research (DESRES) Anton 2 system hosted at PSC, in a "one-two" simulation that shed light on a beta-defensin's initial binding to a microbial membrane. The work promises clues to agents that can better destroy microbes with membranes.

Program Announcements
Application Window for XSEDE EMPOWER Fall Internships and Mentorships Closing Soon
XSEDE EMPOWER (Expert Mentoring Producing Opportunities for Work, Education, and Research) provides undergraduate students with the opportunity to work on a variety of XSEDE projects, such as computational and/or data analytics research and education in all fields of study, networking, system maintenance and support, visualization, and more. Mentors help engage undergrads in the work of XSEDE. The EMPOWER program aims to enable a diverse group of students to participate in the actual work of XSEDE. To apply to mentor one or more students, create one or more positions by following the link below. If you also have a student in mind to work with, that student should also submit an application.  The deadline for mentors and students to apply for Fall 2020 participation is July 10, 2020.

Check out this video to learn more about  XSEDE   EMPOWER  and what two recent interns have to say about the program.
Computing4Change Application Deadline Extended
For undergraduate students who want to enhance their skillset and create positive change in their community, XSEDE is accepting applications for Computing4Change (C4C).   C4C is a competition for students from diverse disciplines and backgrounds who want to work collaboratively to learn to apply data analysis and computational thinking to a social challenge. Currently it is planned to be co-located at SC20 in Atlanta, GA from November 14-20, 2020 (but may become virtual).  The deadline to apply has been extended until July 19, 2020

Community Announcements
Science Gateways Community Institute Offering Internship Opportunity
The Science Gateways Community Institute (SGCI) is now offering academic-year internships for students interested in developing their gateway development skills. Students will receive an hourly salary/stipend (determined by the internship host, based on qualifications) for up to 20 hours of work per week. Application reviews will begin on July 6 for fall placements. For more information, to apply, or to find out how to host an intern, see the link below.

PEARC Seeking Nominations for 2022 Conference Chair and Steering Committee
The Practice and Experience in Advanced Research Computing (PEARC) Conference seeks nominations for individuals to serve in the role of PEARC Steering Committee Members-at-Large and PEARC 2022 Conference General Chair.  Nominations will be accepted until July 12, 2020, at 11:59 pm Central Time.  All members of the community are eligible to serve in these roles. Individuals can self-nominate or nominate another person as a potential Steering Committee member or conference chair. Nomination details and obligations may be found at the link below.

2020 NSF Cybersecurity Summit CFP
The 2020 NSF Cybersecurity Summit hosted by Trusted CI, the NSF Cybersecurity Center of Excellence, will take place September 22–24, 2020 and will be hosted online. 

Attendees include cybersecurity practitioners, technical leaders, and risk owners from within the NSF Large Facilities and CI Community, as well as key stakeholders and thought leaders from the broader scientific and information security communities.

The Summit seeks proposals for presentations, breakout, and training sessions. It offers opportunities for student scholarships.  Those interested in presenting at the Summit should send submissions to  by COB on Monday, July 13.  The Summit organizers welcome proposals from all individuals and agencies.
