Science Highlights
Supercomputing the Secrets of the Inner Ear
XSEDE-allocated supercomputers aid in study of key proteins involved in hearing and balance
The ears don't just help you hear. They also help a person walk, stand, and stay balanced. In fact, they work together with other systems in the body to help one understand our place in space. Many people who have sensations of vertigo find that the problem lies in their inner ears.
Researchers are studying cadherin-23 (CDH23) and protocadherin-15 (PCDH15), two large proteins involved in hearing loss and balance disorders, thanks to supercomputing resources allocated by XSEDE.

MIT Researchers Use Machine Learning to Advance Computational Chemistry
XSEDE-allocated resources simulate complex models
Even though computational chemistry represents a challenging arena for machine learning, a team of researchers from the Massachusetts Institute of Technology (MIT) may have made it easier.
Thanks to allocations from XSEDE, they succeeded in developing an artificial intelligence (AI) approach to detect electron correlation — the interaction between a system's electrons — which is vital but expensive to calculate in quantum chemistry.

Supercomputer Illustrates Mechanical Process of Cancer Growth
XSEDE-allocated resource enables researchers to show cellular "pushing" of collagen
According to the World Health Organization, one in six worldwide deaths has been attributed to cancer. However, these fatalities were not due to initial malignant tumors — the deaths were caused by the spread of cancer cells to surrounding tissues and subsequent tumor growth.
These tissues, which consist largely of collagen, have been the focus of a recent collaborative study by a team from Stanford University and Purdue University. To accomplish their work, the researchers utilized XSEDE allocations to study cancer cell division as what drives the growth of primary and metastatic tumors. Their research singled out the pushing mechanism as the key factor in allowing mitosis to occur.

Program Announcements
PSC's Bridges-2 and SDSC's Expanse Now Allocable by XSEDE
Two relatively new NSF-funded supercomputers, the Bridges-2 platform at the Pittsburgh Supercomputing Center (PSC), and Expanse at the San Diego Supercomputer Center (SDSC), are available for allocation requests via XSEDE. Users who wish to access either resource can request allocations through normal XSEDE allocation channels, including the upcoming March 15-April 15 allocation cycle. More information about each individual resource may be found at the link below.
New Cornell Virtual Workshop Training Opportunities Available with XSEDE
Four new Cornell Virtual Workshop training topics are available at the XSEDE User Portal:
  • Getting Started on Frontera
  • Introduction to Advanced Cluster Architectures
  • Using the Jetstream APIs
  • Python for Data Science: Part 2 - Data Modeling and Machine Learning
Cornell Virtual Workshop topics are freely available at all times to the entire scientific community — researchers, HPC practitioners, students, and educators — at XSEDE Online Training.
Community Announcements
Frontera Expansio
Watch out, disasters and pandemics! The fastest university supercomputer in the world just got faster — thanks to an expansion from the National Science Foundation (NSF)Dell, and Intel — and will help scientists solve societal problems by providing urgent access to massive computing power.
Apply for a One-on-One Engagement with Trusted CI
One of Trusted CI's core activities is conducting one-on-one engagements with NSF projects and facilities. Topics for engagements include anything broadly in the scope of information security and can include the development of new cybersecurity programs, assessing existing cybersecurity programs, software assurance, identity management, or recommendations on new software features. The application deadline for engagements to be executed July-December 2021 is April 2, 2021.
