Podcast: Supercomputing Black Hole Mergers


“General Relativity is celebrating this year a hundred years since its first publication in 1915, when Einstein introduced his theory of General Relativity, which has revolutionized in many ways the way we view our universe. For instance, the idea of a static Euclidean space, which had been assumed for centuries and the concept that gravity was viewed as a force changed. They were replaced with a very dynamical concept of now having a curved space-time in which space and time are related together in an intertwined way described by these very complex, but very beautiful equations.”

Submit Your 2016 Research Allocation Requests for the Bridges Supercomputer


XSEDE is now accepting 2016 Research Allocation Requests for the Bridges supercomputer. Available starting in January, 2016 at the Pittsburgh Supercomputing Center, Bridges represents a new concept in high performance computing: a system designed to support familiar, convenient software and environments for both traditional and non-traditional HPC users.

Over at XSEDE, Scott Gibson writes that Computational Scientist Paul Delgado Says the XSEDE Scholars Program helped him realize his dream of solving real-life problems.

XSEDE & UC Berkeley Offer Online Parallel Computing Course


The XSEDE project and the University of California, Berkeley are offering an online course on parallel computing for graduate students and advanced undergraduates.

XSEDE Powers Polymer Research at MIT

Confined to a tube to approximate the spaghetti-like motion of entangled polymers, a rod–coil block copolymer (rod in blue, coils in pink) moves through a sea of molecules. Flow is impeded when a molecule with a rod passes through a curved portion of the tube (denoted in red). [Image credit: Muzhou “Mitchell” Wang and Christopher N.

Researchers at MIT are using XSEDE resources to study polymers, the chemical compounds used to make plastic, rubber, and more.

Allinea Training Coming to XSEDE15 Conference


Training on Allinea Software will be a featured segment at the XSEDE15 conference in St. Louis next week. The event is designed to help scientists and developers make more efficient use of their time and system allocations.

Video: Introduction to XSEDE 2.0 and Beyond

John Towns, NCSA

This presentation will briefly review XSEDE, its past mission and accomplishments, and give insight into the direction and vision for the second round of XSEDE.

Supercomputing Black Hole Mergers with Blue Waters

Manuela Campanelli, Director of CCRG

“The mathematics involved in simulating these events is very sophisticated because one has to solve the equations of Einstein’s general relativity and magneto-hydrodynamics all together. The problem also requires very advanced supercomputers running programs on tens of thousands of CPUs simultaneously, and the use of sophisticated techniques for data extraction and visualization. Petascale numerical simulation is therefore the only tool available to accurately model these systems.”
