Application Readiness Projects for the Summit Supercomputer Architecture

Dr. Tjerk P. Straatsma from ORNL gave this talk at SC17. “The Center for Accelerated Application Readiness (CAAR) projects are using an Early Access Power8+/Pascal system named SummitDev to prepare for the Power9/Volta system Summit. This presentation highlights achievements on this system, and the experience of the teams that will be a valuable resource for other development teams.”

Radio Free HPC looks at New Leadership at HPE

In this podcast, the Radio Free HPC team looks at HPE’s new CEO, Antonio Neri, a longtime HPE executive who previously served as President of the company. As the number 1 server vendor in the HPC space, this change will be one to watch as we transition to the exascale era in the next five years or so. “This transistion comes at an interesting time for HPE, as one of their main competitors, Dell Technologies, is reportedly looking at an IPO or reverse acquisition by VMware.”

Agenda Posted for April HPC User Forum in Tucson

The HPC User Forum has posted their speaker agenda for their upcoming meeting in Tucson. Hosted by Hyperion Research, the event takes place April 16-18 at Loews Ventana Canyon. “The April meeting will explore the status and prospects for quantum computing and HPC use of HPC for environmental research, especially natural disasters such as earthquakes and the recent California wildfires. As always, the meeting will also look at new developments in HPDA-AI, cloud computing and other areas of continuing interest to the HPC community. A special session will look at the growing field of processors and accelerators supporting HPC systems.”

Let’s Talk Exascale Podcast looks at Parallel I/O with ExaHDF5

In this Let’s Talk Exascale podcast, Suren Byna of LBNL and Quincey Koziol of the NERSC describe ExaHDF5, an I/O platform for exascale data. “One milestone that we have achieved so far is a feature called Data Elevator. The Data Elevator, as it says, is an elevator between different stages of memory hierarchy. It moves the data more transparently so that applications just have to use HDF5 API and internally we take over how to move the data between the layers, so that is one of the features.”

Podcast: Proxy Apps set the stage for Exascale Computing Project

In this Let’s Talk Exascale podcast, David Richard from LLNL discussed the Proxy Apps project, which is curating a collection of proxy apps that will represent the real applications of importance to the ECP. “In this Let’s Talk Exascale podcast, David Richard from LLNL discussed the Proxy Apps project, which is curating a collection of proxy apps that will represent the real applications of importance to the ECP.”

OpenFabrics Alliance Workshop 2018 – An Emphasis on Fabric Community Collaboration

In this special guest feature, Parks Fields and Paul Grun from the OpenFabrics Alliance write that the upcoming OFA Workshop in Boulder is an excellent opportunity to collaborate on the next generation of network fabrics. “Come join the community in Boulder this year to lend your voice to shaping the direction of fabric technology in big ways or small, or perhaps just to listen and learn about the latest trends coming down the pike, or to pick up tips and tricks to make you more effective in your daily job.”

China Readies Exascale Prototype

The Xinhua news service reports that prototype for China’s new-generation exascale supercomputer is set for launch in 2018. “China’s ongoing efforts in HPC are evident in the recent TOP500 list, where the nation has the two fastest supercomputers in the world. In fact, China has overtaken the US in the total number of ranked systems by a margin of 202 to 143.”

Unstructured-Grid CFD Algorithms at NASA on Volta GPUs

Eric Nielsen from NASA gave this talk at SC17 in Denver. “In the field of computational fluid dynamics, the Navier-Stokes equations are often solved using an unstructured-grid approach to accommodate geometric complexity. Furthermore, turbulent flows encountered in aerospace applications generally require highly anisotropic meshes, driving the need for implicit solution methodologies to efficiently solve the discrete equations. To prepare NASA Langley Research Center’s FUN3D CFD solver for the future HPC landscape, we port two representative kernels to NVIDIA Pascal and Volta GPUs and present performance comparisons with a common multi-core CPU benchmark.”

Czech Republic joins EuroHPC Initiative

Today the European Union announced that the Czech Republic is the 14th country to sign the European declaration on high-performance computing. The initiative aims at building European supercomputers that would rank among the world’s top three by 2022-2023. “We are prepared to provide the Czech national HPC capacities and capabilities for this joint mission and contribute to accomplish it successfully.”

Let’s Talk Exascale Podcast: ECP’s Application Assessment Project

In this Let’s Talk Exascale podcast, Kenny Roche from Pacific Northwest National Laboratory describes the ECP’s Application Assessment Project. “With Productivity, we’re aiming to coordinate how to improve software productivity of the code teams and to sustain that performance and development progress to the completion of each ECP application code project.”
