Boost Your HPC & AI Knowledge with Fall Learning Series Webinars

Summer is almost over and fall is the perfect time to refocus, reengage, and reinvest in learning how to overcome some of your biggest HPC challenges. To help get you on track, Cray is offering a September Learning Series of webinars designed to address four of the most frequently asked questions we get in areas ranging from artificial intelligence to storage and compute to software. Join us for any — or all — of the sessions to learn, ask questions and engage with industry thought leaders. Tuesday, 9/11, 9 a.m. PT: The Three Steps: Focusing on Workflow for Successful AI Projects As artificial intelligence (AI) has gained mainstream acceptance, there's been a lot of focus on the systems used to develop and train models. But ... [ Read More ]

Can LS-DYNA Scale Any Higher?

Processing and memory bottlenecks can run but they can’t hide. Not indefinitely, at least. And especially not when four technology leaders combine efforts against them. Cray, Livermore Software Technology Corporation (LSTC), the National Center for Supercomputing Applications (NCSA) and Rolls-Royce are partnering on an ongoing project to explore the future of implicit finite element analyses of large-scale models using LS-DYNA, a multiphysics simulation software package, and Cray supercomputing technology. As the scale of finite element models — and the systems they run on — increase, so do scaling issues and the amount of time it takes to run a model. Understanding that, ultimately, only time and resource constraints limit the size ... [ Read More ]

The Peloton Project: Largest-Ever Sports Simulation Yields Surprising Results

Aerodynamics in a cycling peloton aren’t what you might expect. A peloton is the main field or group of riders in a road bicycle race like the Tour de France. While it can take different shapes, the peloton's overall purpose is to take advantage of the effects of slipstreaming, or drafting, behind other riders. Air resistance is the biggest mechanical component preventing cyclists from going faster on flat road, and slipstreaming can save up to 50 percent of their energy. Or that was the assumption, at least. The reality is that almost no information exists on aerodynamic resistance in cycling pelotons. Systematic computer simulations or measurements have never been reported before. Professor Bert Blocken of Eindhoven ... [ Read More ]

Inside Isambard — the World’s First Production Arm Supercomputer

The Isambard Project, a GW4 Alliance initiative, recently disclosed the latest results from its benchmarking of Arm-based processors for HPC, the first such results for dual socket Cavium ThunderX2 nodes. Prof. Simon McIntosh-Smith gave a talk at the Cray User Group (CUG) Conference in Stockholm on May 23, 2018, in which he described the results of a detailed performance comparison between Cavium™ ThunderX2® Arm®-based CPUs and the latest state-of-the-art Intel Skylake x86 processors. Results focused on the HPC codes that are most heavily used on the UK’s national supercomputer, ARCHER, and showed that for these kinds of workloads, ThunderX2 is competitive with the best x86 CPUs available today, but with a significant cost ...

Your Own Supercomputer — in the Azure Cloud

Your organization relies on technology for a competitive advantage. You need fast, reliable performance. But high-performance computing can be a big investment, and challenging to manage as part of your IT infrastructure. Cray and Microsoft make it easy — and you get Cray supercomputing in the Microsoft Azure cloud. This convergence of supercomputing capabilities and the ease of cloud management enables disruptive innovation for new categories of companies. It alleviates the management burden and reduces barriers of entry to HPC. Supercomputing is no longer out of reach for smaller enterprises and organizations that can’t or don’t want to maintain their own datacenters. Get details about Cray in the cloud in this white paper by ... [ Read More ]
