Jack Dongarra from UT Knoxville gave this talk at ATPESC 2019. “Success in large-scale scientific computations often depends on algorithm design. Even the fastest machine may prove to be inadequate if insufficient attention is paid to the way in which the computation is organized. We have used several problems from computational physics to illustrate the importance of good algorithms, and we offer some very general principles for designing algorithms.”

January 23, 2020 by 2 Comments
In this video, technicians install the Big Red 200 supercomputer at Indiana University. IU is the first university to deploy a Cray Shasta system, the Cray Slingshot interconnect and Cray Urika AI Suite for Shasta, providing its engineers, researchers and scientists powerful resources for the next era of computing. The new supercomputer will be instrumental in the University’s exploration and advancement of AI in education, cybersecurity, medicine, environmental science and more.
Michela Taufer presents: Scientific Applications and Heterogeneous Architectures
January 23, 2020 by Leave a Comment
Michela Taufer from UT Knoxville gave this talk at ATPESC 2019. “This talk discusses two emerging trends in computing (i.e., the convergence of data generation and analytics, and the emergence of edge computing) and how these trends can impact heterogeneous applications. This talk presents case studies of heterogenous applications in precision medicine and precision farming that expand scientist workflows beyond the supercomputing center and shed our reliance on large-scale simulations exclusively, for the sake of scientific discovery.”

Steve Conway from Hyperion Research gave this talk at the Panasas User Group. “Hyperion Research conducted an industry survey to better understand TCO vs. initial costs/other purchase criteria, the benefits of greater simplicity, and buyer/user perceptions of major vendors of HPC storage systems.”
ORNL Tests Arm-based Wombat Platform with NVIDIA GPUs
January 19, 2020 by Leave a Comment
Researchers at ORNL are trying out their HPC codes on Wombat, a test bed cluster based on production Marvell ThunderX2 CPUs and NVIDIA V100 GPUs. The small cluster provides a platform for testing NVIDIA’s new CUDA software stack purpose-built for Arm CPU systems. “Eight teams successfully ported their codes to the new system in the days leading up to SC19. In less than 2 weeks, eight codes in a variety of scientific domains were running smoothly on Wombat.”
HDR 200GB/sec InfiniBand for HPC & AI
January 18, 2020 by Leave a Comment
In this video from the DDN booth at SC19, Scot Schultz from Mellanox presents: Connecting Visions: HDR 200GB/sec InfiniBand. “HDR 200Gb/s InfiniBand accelerates 31 percent of new InfiniBand-based systems on the current TOP500, including the fastest TOP500 supercomputer built this year. The results also highlight InfiniBand’s continued position in the top three supercomputers in the world and acceleration of six of the top 10 systems. Since the TOP500 List release in June 2019, InfiniBand’s presence has increased by 12 percent, now accelerating 141 supercomputers on the List.”
200G HDR InfiniBand to Accelerate Weather Forecasting at ECMWF
January 17, 2020 by Leave a Comment
Today Mellanox announced that 200 Gigabit HDR InfiniBand has been selected by the European Centre for Medium-Range Weather Forecasts (ECMWF) to accelerate their new world-leading supercomputer, based on Atos’ latest BullSequana XH2000 technology. By leveraging HDR InfiniBand’s fast data throughout, extremely low latency, and smart In-Network Computing engines, ECMWF will enhance, speed up, and increase the accuracy of weather forecasting and predictions.
Supercomputing the Mysteries of Boron Carbide
January 17, 2020 by Leave a Comment
Researchers at the University of Florida are using XSEDE supercomputers to unlock the mysteries of boron carbide, one of the hardest materials on earth. The material is also very lightweight, which explains why it has been used in making vehicle armor and body protection for soldiers. The research, which primarily used the Comet supercomputer at the San Diego Supercomputer Center along with the Stampede and Stampede2 systems at the Texas Advanced Computing Center, may provide insight into better protective mechanisms for vehicle and soldier armor after further testing and development.
