Texas Advanced Computing Center (TACC) researcher Paul Navratil, with support from the U.S. National Science Foundation (NSF), is leading an effort to design GraviT, a new framework that would enable tens of thousands of scientists and engineers who use the U.S.'s supercomputers to add ray tracing visualizations to their research, regardless of the type of computing systems or hardware they...

Engineers at the University of California, San Diego, have developed a new family of methods to significantly increase the speed of time-resolved numerical simulations in computational grand challenge problems.  Such problems often arise from the high-resolution approximation of the partial differential equations governing complex flows of fluids or plasmas. The breakthrough could be...

When astronomers try to simulate colliding giant black holes, they usually rely on simplified approximations to model the swirling disks of matter that surround and fuel these gravitational monsters. Researchers now report that, for the first time, they have simulated the collision of two supermassive black holes using a full-blown treatment of Einstein’s general theory of relativity,...

It all begins in the brain as a flood, tens of millions of neurotransmitters handed off from one neuron to another in just a fraction of a second. Stubborn walls that enclose our neurons keep out the signal flow of one cell to another needed for brain activity. Chemists call this gatekeeper of our thoughts an ion channel, which takes a key in the form of a chemical neurotransmitter,...

InsideHPC In this special guest feature from Scientific Computing World , Bill Clark, executive vice president of CD-adapco, considers the successes of computer-aided engineering through the “three ages of CFD. Computational Fluid Dynamics (CFD) is about solving difficult engineering problems, using expensive software, enormous computing resources, and highly trained engineers. If the...

Quartz In 2006, former ACM president Maria Klawe was appointed Harvey Mudd College president and immediately helped changed the computer science department to try to encourage more female students to enroll in computer science classes. First, the course previously called "Introduction to programming in Java," was renamed "Creative approaches to problem solving in science and...
