Video: Introduction to OpenACC

Vasileios Karakasis from CSCS gave this talk at the the Directive Based GPU Programming Workshop. “Directives-based programming facilitates the task of parallelizing your application by letting you focus on its parallel logic rather than on the very details and the low-level intricacies of the GPU architecture. In this course, we will introduce the OpenACC programming paradigms for the GPU. We will cover the parallel execution model and how it can be used to leverage parallelism, the memory model and how this differs from the classic CPU paradigm.”

Tachyum Touts Benefits of Universal Processor at HOT CHIPS

This week at the Hot Chips conference, Tachyum CEO Dr. Radoslav Danilak described how the company’s its Prodigy Universal Processor Chip combines the best attributes of CPU, GPU and TPU architectures to overcome HPC challenges. “I look forward to sharing with attendees at HOT CHIPS how a new approach is needed to overcome the challenges faced by all those in the hyperscale datacenter, HPC and AI markets.”

Video: Accelerated Any-Scale Ai Solutions from DDN

In this video from the DDN User Group at ISC 2018, James Coomer from DDN presents: A3I – Accelerated Any-Scale Solutions from DDN. “Engineered from the ground up for the AI-enabled data center, DDN’s A3I solutions are fully optimized to handle the spectrum of AI and DL activities concurrently: data ingest and preparation, training, validation, and inference. The DDN A3I platform is easy to deploy and manage, highly scalable in both performance and capacity, and represents a highly efficient and resilient solution for all of your current and future AI requirements.”

Video: Massive Galaxies and Black Holes at the Cosmic Dawn

Tiziana DiMatteo from Carnegie Melon University gave this talk at the 2018 Blue Waters Symposium. “The first billion years is a pivotal time for cosmic structure formation. The galaxies and black holes that form then shape and influence all future generations of stars and black holes. Understanding and detecting the the first galaxies and black holes is therefore one of the main observational and theoretical challenges in galaxy formation.”

Extreme Computing for Extreme Adaptive Optics: The Key to Finding Life Outside our Solar System

Hatem Ltaief from KAUST gave this talk at PASC18. “The real-time correction of telescopic images in the search for exoplanets is highly sensitive to atmospheric aberrations. The pseudo-inverse algorithm is an efficient mathematical method to filter out these turbulences. We introduce a new partial singular value decomposition (SVD) algorithm based on QR-based Diagonally Weighted Halley (QDWH) iteration for the pseudo-inverse method of adaptive optics. The pseudo-inverse simulation code will be deployed on-sky for the Subaru telescope during observation nights scheduled early 2018.”

Video: NVIDIA Announces Turing GPUs and CUDA Toolkit 10

Today at SIGGRPAH, NVIDIA announced its newest GPUs based on the new Turing architecture. ”
This fundamentally changes how computer graphics will be done, it’s a step change in realism,” Huang told an audience of more than 1,200 graphics pros gathered at the sleek glass and steel Vancouver Convention Center, which sits across a waterway criss-crossed by cruise ships and seaplanes from the stunning North Shore mountains.

Lenovo Takes the TOP500 with Liquid Cooling at ISC 2018

In this video from ISC 2018, Rick Koopman from Lenovo describes the company’s latest HPC innovations including their new Neptune liquid cooling technology. Lenovo is the world’s largest TOP500 supercomputing provider measured by the number of systems ranked on the TOP500 list. 117 of the 500 most powerful supercomputers included in the TOP500 are Lenovo installations, meaning nearly one out of every four systems (23.4 percent) on the prestigious list is a Lenovo solution.

Training Generative Adversarial Models over Distributed Computing Systems

Gul Rukh Khattak from CERN gave this talk at PASC18. “We use a dataset composed of the energy deposition from electron, photons, charged and neutral hadrons in a fine grained digital calorimeter. The training of these models is quite computing intensive, even with the help of GPGPU, and we propose a method to train them over multiple nodes and GPGPU using a standard message passing interface. We report on the scalings of time-to-solution.”

PASC18 Panel Discussion Big Data vs. Fast Computation

“The panelists will discuss the critical challenges facing key HPC application areas in the next 5-10 years, based on a mix of knowledge and speculation. They will explore whether we need to make radical changes to our practices, methods, tools, and techniques to be able to use modern resources and make faster and bigger progress on our scientific problems.”

Dr. Eng Lim Goh presents: Prediction – Use Science or History?

Dr. Eng Lim Goh from HPE gave this keynote talk at PASC18. “Traditionally, scientific laws have been applied deductively – from predicting the performance of a pacemaker before implant, downforce of a Formula 1 car, pricing of derivatives in finance or the motion of planets for a trip to Mars. With Artificial Intelligence, we are starting to also use the data-intensive inductive approach, enabled by the re-emergence of Machine Learning which has been fueled by decades of accumulated data.”
