Podcast: Is Our Future Liquid Cooled?

In this podcast, the Radio Free HPC team looks at the growing trend of liquid cooling in the datacenter. “The new VSC-4 system built by Lenovo checks in at #82 on the TOP500 list and is liquid cooled, leading to a debate on the future of cooling and various forms of liquid-cooling: direct contact, immersion, and phase change.”

The Convergence of HPC and AI

In this special guest feature, Bill Wagner from Bright Computing writes that the convergence of HPC & AI presents new challenges for containers, job scheduling, and system management. “But here’s the rub … traditional HPC applications run under the jurisdiction of an HPC workload manager like Slurm or PBS Pro, whereas machine learning applications are primarily run in containers under the jurisdiction of a container orchestration system, such as Kubernetes.”

Considerations for Managing HPC Resources

In this special guest feature, Robert Roe from Scientific Computing World writes that companies faced with increasing complexity are developing new services and tools to help users manage their HPC resources. “The single biggest thing that people do is focus too much on the hardware, and forget about the rest of the stuff. The procurement process is driven by the compute system. It doesn’t necessarily take into account that you are going to need people and software to deliver value,” said Andrew Jones from NAG.

Podcast: Is Cloud too expensive for HPC?

Is Cloud too expensive for HPC? Enquiring minds want to know, as does the HPC community whose single-minded obsession with maximum price-performance is notorious and legendary. The Radio Free team looks at actual cloud pricing based on available data and Dan’s research which fuel a hearty discussion. They look at configurations, compare prices, talk about the costs that are not included, segment the market, and then segment the applications.

Why PASC19 is a great show for the International Science Community

In this video from PASC19 in Zurich, Mike Heroux from Sandia National Labs shares the reasons he attends the conference every year. As a multi-disciplinary show, PASC gives him the opportunity to keep up with the international science community. “PASC19 is the sixth edition of the PASC Conference series, an international platform for the exchange of competences in scientific computing and computational science, with a strong focus on methods, tools, algorithms, application challenges, and novel techniques and usage of high performance computing.”

Video: Update on the Exascale Computing Project

In this video, ECP Director Doug Kothe provides an update on the Exascale Computing Project. ECP has mission to ensure that a capable exascale computing ecosystem will come to fruition with the arrival of the nation’s first exascale systems. “Enduring legacy translates to having dozens of application technologies that will be used to tackle some of the toughest problems in DOE and the nation, and so the applications are now going to be positioned to address their challenge problems and in many cases help solve them or be a part of the solution.”

High Performance Systems: An “Open Plan” for HPC

In this special guest feature from the SC19 Blog, Ryan Quick from Providentia Worldwide calls for a conference program that reflects more sharing across disciplines. “For me, HPC is about delivering answers to hard questions – right now. It’s about an inclusive and integrative approach to computing. And it’s exciting. If we can put aside our differences and allow ourselves to learn a little. We will gain a lot. I promise. See you in Denver.”

Multiple Endpoints in the Latest Intel MPI Library Boosts Hybrid Performance

The performance of distributed memory MPI applications on the latest highly parallel multi-core processors often turns out to be lower than expected. Which is why hybrid applications using OpenMP multithreading on each node and MPI across nodes in a cluster are becoming more common. This sponsored post from Intel, written by Richard Friedman, depicts how to boost performance for hybrid applications with multiple endpoints in the Intel MPI Library. 

Video: Hyperion Research – Market Insight for HPC & AI

In this video, the Hyperion Research team describes how the company helps customers make fact-based decisions on technology purchases and business strategy. “Our industry experts are the former IDC high performance computing analyst team, which remains intact and continues all of its global activities. The group is comprised of the world’s most respected HPC industry analysts who have worked together for more than 25 years.”

Podcast: Quantum Applications are Always Hybrid

In this podcast, the Radio Free HPC team looks at inherently hybrid nature of quantum computing applications. “If you’re always going to have to mix classical code with quantum code then you need an environment that is built for that workflow, and thus we see a lot of attention given to that in the QIS (Quantum Information Science) area. This is reminiscent of OpenGL for graphics accelerators and OpenCL/CUDA for compute accelerators.”
