Call for Papers: International Workshop on Performance-Portable Programming Models for Accelerators

The first annual International Workshop on Performance Portable Programming Models for Accelerators has issued its Call for Papers. Known as P^3MA, the workshop will provide a forum for bringing together researchers, vendors, users and developers to brainstorm aspects of heterogeneous computing and its various tools and techniques.

2016 OpenPOWER Summit Announces Speaker Agenda

Today, the OpenPOWER Foundation announced the lineup of speakers for the OpenPOWER Summit 2016, taking place April 5-8 at NVIDIA’s GPU Technology Conference (GTC) at the San Jose Convention Center. The Summit will bring together dozens of technology leaders from the OpenPOWER Foundation to showcase the latest advancements in the OpenPOWER ecosystem, including collaborative hardware, software and application developments – all designed to revolutionize the data center.

Video: Supercomputing at the University of Buffalo

In this WGRZ video, researchers describe supercomputing at the Center for Computational Research at the University of Buffalo. “The Center’s extensive computing facilities, which are housed in a state-of-the-art 4000 sq ft machine room, include a generally accessible (to all UB researchers) Linux cluster with more than 8000 processor cores and QDR Infiniband, a subset (32) of which contain (64) NVidia Tesla M2050 “Fermi” graphics processing units (GPUs).”

Call for Contributions: Hot Chips 2016

hotchipsThe Hot Chips 2016 conference has issues its Call for Proposals. The event takes place August 21-23 in Cupertino, California. “Presentations at HOT CHIPS are in the form of 30 minute talks using PowerPoint or PDF. Presentation slides will be published in the HOT CHIPS Proceedings. Participants are not required to submit written papers, but a select group will be invited to submit a paper for inclusion in a special issue of IEEE Micro.”

Video: AMD’s next Generation GPU and High Bandwidth Memory Architecture

“HBM is a new type of CPU/GPU memory (“RAM”) that vertically stacks memory chips, like floors in a skyscraper. In doing so, it shortens your information commute. Those towers connect to the CPU or GPU through an ultra-fast interconnect called the “interposer.” Several stacks of HBM are plugged into the interposer alongside a CPU or GPU, and that assembled module connects to a circuit board. Though these HBM stacks are not physically integrated with the CPU or GPU, they are so closely and quickly connected via the interposer that HBM’s characteristics are nearly indistinguishable from on-chip integrated RAM.”

Video: Bill Dally on Scaling Performance in the Post-Dennard Era

“It was indicated in my keynote this morning there are two really fundamental challenges we’re facing in the next two years in all sorts of computing – from supercomputers to cell phones. The first is that of energy efficiency. With the end of Dennard scaling, we’re no longer getting a big improvement in performance per watt from each technology generation. The performance improvement has dropped from a factor of 2.8 x back when we used to scale supply voltage with each new generation, now to about 1.3 x in the post-Dennard era. With this comes a real challenge for us to come up with architecture techniques and circuit techniques for better performance per watt.”

The GPUltima: Up to a Petaflop of Networked GPUs in a Single Rack

In this week’s industry Perspective, Katie Garrison of One Stop Systems explains how GPUltima allows HPC professionals to create a highly dense compute platform that delivers a petaflop of performance at greatly reduced cost and space requirements.compute power needed to quickly process the amount of data generated in intensive applications.

Call for Submissions: GPU Hackathon at the University of Delaware

The Call for Submissions is open for the upcoming GPU Programming Hackathon at University of Delaware (UDEL). The event takes place from May 2-6, 2016 at UDEL in Newark, Delaware.

Long Live the King – The Complicated Business of Upgrading Legacy HPC Systems

“Upgrading legacy HPC systems relies as much on the requirements of the user base as it does on the budget of the institution buying the system. There is a gamut of technology and deployment methods to choose from, and the picture is further complicated by infrastructure such as cooling equipment, storage, networking – all of which must fit into the available space. However, in most cases it is the requirements of the codes and applications being run on the system that ultimately define choice of architecture when upgrading a legacy system. In the most extreme cases, these requirements can restrict the available technology, effectively locking a HPC center into a single technology, or restricting the application of new architectures because of the added complexity associated with code modernization, or porting existing codes to new technology platforms.”

GPUs & Liquid-Cooling Speed APEXX 5 Advanced Computer Workstation

Apexx5_hero_web_smallToday BOXX Technologies introduced the redesigned APEXX 5, the “world’s most advanced professional workstation.” Built to accommodate demanding engineering, architectural, VFX, and animation workflows, the newly upgraded and highly configurable APEXX 5 is designed to maximize I/O expandability with up to 5 dual-width GPUs with a sync card, a single-width GPU, or any combination of seven, full-length expansion cards while reaching new levels of rendering and simulation performance.
