Radio Free HPC Looks at Diverging Chip Architectures in the Wake of Spectre and Meltdown

In this podcast, the Radio Free HPC team looks at the tradeoff between chip performance and security. In the aftermath of the recently disclosed Spectre and Meltdown exploits, Cryptograpy guru Paul Kocher from Rambus is calling for a divergence in processor architectures:

HACC: Fitting the Universe inside a Supercomputer

Nicholas Frontiere from the University of Chicago gave this talk at the DOE CSGF Program Review meeting. “In response to the plethora of data from current and future large-scale structure surveys of the universe, sophisticated simulations are required to obtain commensurate theoretical predictions. We have developed the Hardware/Hybrid Accelerated Cosmology Code (HACC), capable of sustained performance on powerful and architecturally diverse supercomputers to address this numerical challenge. We will investigate the numerical methods utilized to solve a problem that evolves trillions of particles, with a dynamic range of a million to one.”

Job of the Week: HPC Systems Engineer at Washington State University

The Center for Institutional Research Computing at Washington State University is seeking a High-Performance Computing Systems Engineer in our Job of the Week. “This position will play a vital role in the engineering and administration of HPC clusters used by the research community at Washington State University. This position is an exciting opportunity to participate in the frontiers of research computing through the selection, configuration, and management of HPC infrastructure including all computing systems, networking, and storage. This position is key to ensuring the high quality of service and performance of WSU’s research computing resources.”

Video: Deep Reinforcement Learning and Systems Infrastructure at DeepMind

In this video from HiPEAC 2018 in Manchester, Dan Belov from DeepMind describe the company’s machine learning technology and some of the challenges ahead. “DeepMind Inc. is well known for state of the art Deep Reinforcement Learning (DRL) algorithms such as DQN on Atari, A3C on DMLab and AlphaGo Zero. I would like to take you on a tour of challenges we encounter when training DRL agents on large workloads with hundreds of terabytes of data. I’ll talk about why DRL poses unique challenges when designing distributed systems and hardware as opposed to simple supervised learning. Finally I’d like to discuss opportunities for DRL to help systems design and operation.”

Adaptive Computing rolls out Moab HPC Suite 9.1.2

Today Adaptive Computing announced the release of Moab 9.1.2, an update which has undergone thousands of quality tests and includes scores of customer-requested enhancements. “Moab is a world leader in dynamically optimizing large-scale computing environments. It intelligently places and schedules workloads and adapts resources to optimize application performance, increase system utilization, and achieve organizational objectives. Moab’s unique intelligent and predictive capabilities evaluate the impact of future orchestration decisions across diverse workload domains (HPC, HTC, Big Data, Grid Computing, SOA, Data Centers, Cloud Brokerage, Workload Management, Enterprise Automation, Workflow Management, Server Consolidation, and Cloud Bursting); thereby optimizing cost reduction and speeding product delivery.”

Intel Rolls out new 3D NAND SSDs

Today, Intel announced the Intel SSD DC P4510 Series for data center applications. As a high performance storage device, the P4510 Series uses 64-layer TLC Intel 3D NAND to enable end users to do more per server, support broader workloads, and deliver space-efficient capacity. “The P4510 Series enables up to four times more terabytes per server and delivers up to 10 times better random read latency at 99.99 percent quality of service than previous generations. The drive can also deliver up to double the input-output operations per second (IOPS) per terabyte.”

Interview: European cHiPSet Event focuses on High-Performance Modeling and Simulation for Big Data Applications

The cHIPSet Annual Plenary Meeting takes place in France next month. To learn more, we caught up with the Vice-Chair for the project, Dr. Horacio González-Vélez, Associate Professor and Head of the Cloud Competency Centre at the National College of Ireland. “The plenary meeting will feature a workshop entitled “Accelerating Modeling and Simulation in the Data Deluge Era”. We are expecting keynote presentations and panel discussions on how the forthcoming exascale systems will influence the analysis and interpretation of data, including the simulation of models, to match observation to theory.”

TACC Podcast Looks at AI and Water Management

In this TACC podcast, Suzanne Pierce from the Texas Advanced Computing Center describes her upcoming panel discussion on AI and water management and the work TACC is doing to support efforts to bridge advanced computing with Earth science. “It’s about letting the AI help us be better decision makers. And it helps us move towards answering, discussing, and exploring the questions that are most important and most critical for our quality of life and our communities so that we can develop a future together that’s brighter.”

Call for Papers: International Workshop on In Situ Visualization

The 3rd International Workshop on In Situ Visualization has issued it’s Call for Papers. Held in conjunction with ISC 2018, WOIV 2018 takes place June 28 in Frankfurt, Germany. “Our goal is to appeal to a wide-ranging audience of visualization scientists, computational scientists, and simulation developers, who have to collaborate in order to develop, deploy, and maintain in situ visualization approaches on HPC infrastructures. We hope to provide practical take-away techniques and insights that serve as inspiration for attendees to implement or refine in their own HPC environments and to avoid pitfalls.”

PASC18 Keynote to Focus on Extreme-Scale Multi-Physics Earthquake Simulations

Today the PASC18 conference announced that Alice-Agnes Gabriel from Ludwig-Maximilian-University of Munich will deliver a keynote address on earthquake simulation. ” This talk will focus on using physics-based scenarios, modern numerical methods and hardware specific optimizations to shed light on the dynamics, and severity, of earthquake behavior. It will present the largest-scale dynamic earthquake rupture simulation to date, which models the 2004 Sumatra-Andaman event – an unexpected subduction zone earthquake which generated a rupture of over 1,500 km in length within the ocean floor followed by a series of devastating tsunamis.”
