Scale Performance from Multicore to Many-Core

Implementing a parallel algorithm can get frustrating at times. Developers can thread an application, but see little performance gain. Or they can hit a scalability ceiling where performance gains level off as more cores are added. A newly updated tool, the Advisor XE 2015, can help solve those issues by …

Boost Your App Performance with Optimization Reports

Intel’s latest compilers produce new, user-friendly optimization reports that provide developers the information they need to increase the performance of their applications. Previous compilers scattered information across different reports, resulting in messages that were cryptic, confusing or not logically ordered. The single report stream was also hard to navigate, hard …

Catching Gravitational Waves to Answer Big Bang Questions

Scientists have long believed that galactic events, such as supernova explosions or black hole mergers, leave a trace called gravitational waves, which are ripples in the fabric of space-time much like how a boat produces waves in the water. Now scientists are beginning to take advantage of supercomputers — specifically, …

World’s Fastest Astronomical Supercomputer Reaches Petascale Speeds

The world’s fastest supercomputer for astronomical research just got a lot faster. The National Astronomical Observatory of Japan’s Center for Computational Astrophysics (CfCA) has doubled the power of its Aterui supercomputer, from 502 teraflops to 1.058 petaflops per second, according to a recent press release. In order to meet increased …

Supercomputer Solves Genealogical Mystery

Scientists who have used a supercomputer to compare modern and ancient DNA have discovered that most modern Europeans come from three distinct groups of people. The three populations are blue-eyed hunter-gatherers that arrived in Europe 40,000 years ago, light-skinned brown-eyed farmers from the near East who migrated about 7,000 years …

Comet Supercomputer Extends Reach of HPC Power

The San Diego Supercomputer Center (SDSC) plans to launch a new supercomputer next spring that is designed to meet the needs of researchers who have not traditionally used high-performance computing (HPC) in the past, such as those in social sciences, economics or genomics. The new $21.6 million supercomputer, called Comet, …
