Latest Climate Models Predict Thinner Clouds and More Global Warming

Thanks to clouds, latest climate models predict more global warming than their predecessors. Researchers at LLNL in collaboration with colleagues from the University of Leeds and Imperial College London have found that the latest generation of global climate models predict more warming in response to increasing carbon dioxide. “If global warming leads to fewer or thinner clouds, it causes additional warming above and beyond that coming from carbon dioxide alone. In other words, an amplifying feedback to warming occurs.”

Podcast: Optimizing Math Libraries to Prepare Applications for Exascale

In this episode of Let’s Talk Exascale, Ulrike Meier Yang of LLNL describes the xSDK4ECP and hypre projects within the Exascale Computing Project. The increased number of libraries that exascale will need presents challenges. “The libraries are harder to build in combination, involving many variations of compilers and architectures, and require a lot of testing for new xSDK releases.”

Podcast: UnifyFS Software Project steps up to Exascale

In this Let’s Talk Exascale podcast, Kathryn Mohror LLNL and Sarp Oral of ORNL provide an update ECP’s ExaIO project and UnifyFS. “UnifyFS can provide ECP applications performance-portable I/O across changing storage system architectures, including the upcoming Aurora, Frontier, and El Capitan exascale machines. “It is critically important that we provide this portability so that application developers don’t need to spend their time changing their I/O code for every system.”

Penguin Computing to Deploy Magma Supercomputer with Intel Xeon Platinum 9200 Processors at LLNL

At SC19, Penguin Computing announced a powerful new supercomputer coming to Lawrence Livermore National Laboratory. Called Magma, the system was procured through the Commodity Technology Systems (CTS-1) contract with the National Nuclear Security Administration (NNSA) and is one of the first deployments of Intel Xeon Platinum 9200 series processors with support from CoolIT Systems complete direct liquid cooling and the Intel Omni-Path interconnect.

Cray and Fujitsu to bring Game-Changing Arm A64FX Processor to Global HPC Market

Today Cray and Fujitsu announced a partnership to offer high performance technologies for the exascale era. Under the alliance agreement, Cray is developing the first-ever commercial supercomputer powered by the Fujitsu A64FX Arm-based processor with high-memory bandwidth (HBM) and supported on the proven Cray CS500 supercomputer architecture and programming environment.

Department of Energy to Showcase World-Leading Science at SC19

The DOE’s national laboratories will be showcased at SC19 next week in Denver, CO. “Computational scientists from DOE laboratories have been involved in the conference since it began in 1988 and this year’s event is no different. Experts from the 17 national laboratories will be sharing a booth featuring speakers, presentations, demonstrations, discussions, and simulations. DOE booth #925 will also feature a display of high performance computing artifacts from past, present and future systems. Lab experts will also contribute to the SC19 conference program by leading tutorials, presenting technical papers, speaking at workshops, leading birds-of-a-feather discussions, and sharing ideas in panel discussions.”

HP-CAST Returns to Denver for SC19

Hewlett Packard Enterprise has posted the preliminary agenda for their HP-CAST user group meeting. The event takes place Nov. 15-16 in Denver, right before SC19. “The High Performance Consortium for Advanced Scientific and Technical (HP-CAST) computing works to increase the capabilities of innovative HPE solutions for HPC and AI. HP-CAST provides guidance to Hewlett Packard Enterprise on the essential development and support issues for such systems.”

First Annual Exascale Day on 10/18 to Celebrate Supercomputing Discoveries

“Exascale Day celebrates the scientists and researchers who make breakthrough discoveries with the help of some of the fastest supercomputers in the world. Exascale Day celebrates those who keep asking what if, why not, and what’s next — with the advanced technology to attain the answers. The founding organizations have established National Exascale Day as a registered holiday to be celebrated annually on October 18 (1018).”

Video: Managing HPC Software Complexity with Spack

Greg Becker from LLNL gave this talk at the MVAPICH User Group. “Spack is an open-source package manager for HPC. This presentation will give an overview of Spack, including recent developments and a number of items on the near-term roadmap. We will focus on Spack features relevant to the MVAPICH community; these include Spack’s virtual package abstraction, which is used for API-compatible libraries including MPI implementations, package level compiler wrappers, and packages which modify other package’s build environments.”

Cray Shasta Software to Power Exascale Era

Today Cray a new, open and extensible software platform to address the growing need for supercomputing across government and private industries. As advanced simulation, artificial intelligence (AI) and digital transformation create new, data intensive workloads, the need for performance at scale is growing rapidly. Recognizing the challenges presented by the exascale era, Cray’s software fuses supercomputing performance and capability with the modularity, composability and ease-of-use of cloud computing.
