Staff from the Oak Ridge Leadership Computing Facility (OLCF), a US Department of Energy (DOE)Office of Science User Facility, held prominent roles in two recent committee meetings—one focused on OpenACC and one devoted to OpenMP.
“Space Debris are defunct objects in space, including old space vehicles (such as satellites or rocket stages) or fragments from collisions. Space debris can cause great damage to functional space ships and satellites. Thus detection of space debris and prediction of their orbital paths are essential for today’s operation of space missions. The talk shows the Python-based infrastructures BACARDI for gathering and storing space debris data from sensors and Skynet for high-throughput data processing and orbital collision detection.”
“The fast fourier transform (FFT) algorithm is a powerful tool for looking at time-based measurements in an interesting way, but do you understand what it does? This talk will start from basic geometry and explain what the fourier transform is, how to understand it, why it’s useful and show examples. If you’re collecting time-series data (e.g. heart rate, stock prices, server usage, temperature) the fourier transform can be a useful tool for analyzing the underlying periodic nature of the data.”
As reported here, President Obama established the National Strategic Computing Initiative (NSCI) in July to ensure the United States continues leading high performance computing over the coming decades. Today, IDC announced what promises to be the first NSCI discussion involving the lead agencies at their next HPC User Forum.
In this video from the ISC 2015 conference, Erich Strohmaier from NERSC and Jack Dongarra from University of Tennessee discuss the latest HPC trends reflected in the 45th TOP500 list. “Nine systems in the top 10 were installed in 2011 or 2012, and this low level of turnover among the top supercomputers reflects a slowing trend that began in 2008.”
