Exascale Computing – What are the Goals and the Baseline?

Thomas Schulthess presented this talk at the MVAPICH User Group. “Implementation of exascale computing will be different in that application performance is supposed to play a central role in determining the system performance, rather than just considering floating point performance of the high-performance Linpack benchmark. This immediately raises the question as to what the yardstick will be, by which we measure progress towards exascale computing. I will discuss what type of performance improvements will be needed to reach kilometer-scale global climate and weather simulations. This challenge will probably require more than exascale performance.”

Requesting Your Input on the HPC Customer Experience Survey

We’d like to invite our readers to participate in our new HPC Customer Experience Survey. It’s an effort to better understand our readers and what is really happening out there in the world of High Performance Computing. “This survey should take less than 10 minutes to complete. All information you provide will be treated as private and kept confidential.”

SGI Opens European Research Centre at ICHEC in Ireland

Today SGI announced a significant investment in extreme scale software research at the Irish Centre for High-End Computing (ICHEC), a top European center. The investment highlights the commitment of SGI to the European software research community. These resources, including SGI application software and supercomputing hardware expertise, will assist scientists as they explore issues related to climate change, weather forecasting, and environmental research among many other topics.

Simulating the Earliest Generations of Galaxies with Enzo and Blue Waters

“Galaxies are complex—many physical processes operate simultaneously, and over a huge range of scales in space and time. As a result, accurately modeling the formation and evolution of galaxies over the lifetime of the universe presents tremendous technical challenges. In this talk I will describe some of the important unanswered questions regarding galaxy formation, discuss in general terms how we simulate the formation of galaxies on a computer, and present simulations (and accompanying published results) that the Enzo collaboration has recently done on the Blue Waters supercomputer. In particular, I will focus on the transition from metal-free to metal-enriched star formation in the universe, as well as the luminosity function of the earliest generations of galaxies and how we might observe it with the upcoming James Webb Space Telescope.”

OpenHPC – Community Building Blocks for HPC Systems

Karl Schulz from Intel presented this talk at the 4th Annual MVAPICH User Group meeting. “Today, many supercomputing sites spend considerable effort aggregating a large suite of open-source projects on top of their chosen base Linux distribution in order to provide a capable HPC environment for their users. This presentation will introduce a new, open-source HPC community (OpenHPC) that is focused on providing HPC-centric package builds for a variety of common building-blocks in an effort to minimize duplication, implement integration testing to gain validation confidence, incorporate ongoing novel R&D efforts, and provide a platform to share configuration recipes from a variety of sites.”

Radio Free HPC Looks at Alternative Processors for High Performance Computing

In this podcast, the Radio Free HPC team looks at why it’s so difficult for new processor architectures to gain traction in HPC and the datacenter. Plus, we introduce a new regular feature for our show: The Catch of the Week.

Students Learn Supercomputing at the Summer of HPC in Barcelona

In this video, students describe their learning experience at the 2016 PRACE Summer of HPC program in Barcelona. “The PRACE Summer of HPC is a PRACE outreach and training program that offers summer placements at top HPC centers across Europe to late-stage undergraduates and early-stage postgraduate students. Up to twenty top applicants from across Europe will be selected to participate. Participants spend two months working on projects related to PRACE technical or industrial work and produce a report and a visualization or video of their results.”

There’s Still Time to Show Why HPC Matters in the SC16 Impact Showcase

SC16 has extended the application deadline for its Impact Showcase, a forum designed to show attendees why HPC Matters in the real world. Submissions are now due Sept. 15.

Extreme-scale Graph Analysis on Blue Waters

George Slota presented this talk at the Blue Waters Symposium. “In recent years, many graph processing frameworks have been introduced with the goal to simplify analysis of real-world graphs on commodity hardware. However, these popular frameworks lack scalability to modern massive-scale datasets. This work introduces a methodology for graph processing on distributed HPC systems that is simple to implement, generalizable to broad classes of graph algorithms, and scales to systems with hundreds of thousands of cores and graphs of billions of vertices and trillions of edges.”

Job of the Week: Data Operations Specialist at the Simons Foundation

“The Simons Foundation is beginning a new computational science organization called the Flatiron Institute. Flatiron will seek to explore challenging science problems in astrophysics, biology and chemistry. Computational science techniques involve processing and simulation activities and large-scale data analysis. This position is intended to help manage and fully exploit the data and storage resources at Flatiron to further the scientific mission.”
