Chapel Comes of Age: a Language for Productivity, Parallelism, and Performance

Brad Chamberlain from Cray gave this talk at the HPCKP’19 conference. “Though Chapel has been under development for some time now, its performance and feature  set have only recently reached the point where it can seriously be considered by users with HPC-scale scientific, data analytic, and artificial intelligence workloads. In this talk, I will introduce Chapel for those who are new to the language, and cover recent advances, milestones, and performance results for those who are already familiar with it.”

Dr. Steven Squyres from Cornell to Keynote SC19

Dr. Steven Squyres from Cornell University will keynote the SC19 conference in Denver. His talk will be entitled “Exploring the Solar System with the Power of Technology.” Steve Squyres’ research focuses on the robotic exploration of planetary surfaces, the history of water on Mars, geophysics and tectonics of icy satellites, tectonics of Venus, planetary gamma-ray and x-ray spectroscopy.

A Performance Comparison of Different MPI Implementations on an ARM HPC System

Nicholas Brown from EPCC gave this talk at the MVAPICH User Group. “In this talk I will describe work we have done in exploring the performance properties of MVAPICH, OpenMPI and MPT on one of these systems, Fulhame, which is an HPE Apollo 70-based system with 64 nodes of Cavium ThunderX2 ARM processors and Mellanox InfiniBand interconnect. In order to take advantage of these systems most effectively, it is very important to understand the performance that different MPI implementations can provide and any further opportunities to optimize these.”

Overview of the MVAPICH Project and Future Roadmap

DK Panda gave this talk at the MVAPICH User Group. “This talk will provide an overview of the MVAPICH project (past, present, and future). Future roadmap and features for upcoming releases of the MVAPICH2 software family (including MVAPICH2-X and MVAPICH2-GDR) for HPC and Deep Learning will be presented. Features and releases for Microsoft Azure and Amazon AWS will also be presented. Current status and future plans for OSU INAM, OMB, and Best Practices Page will also be presented.”

Cooling Challenges for Ultra-high Density Compute Clusters

Miguel Terol from Lenovo gave this talk at HPCKP’19. “Technology players are refining their chip and platform designs to enable much denser systems. The trade-off of this trend is chips are getting more and more power hungry, and cooling those components becomes a challenge in terms of sustainability, either for the environment or the economy. In this talk we will present the high density technology landscape and different approaches to address the cooling challenges.”

Video: InfiniBand In-Network Computing Technology and Roadmap

Gilad Shainer from Mellanox gave this talk at the MVAPICH User Group. “In-Network Computing transforms the data center interconnect to become a “distributed CPU”, and “distributed memory”, enables to overcome performance barriers and to enable faster and more scalable data analysis. These technologies are in use at some of the recent large scale supercomputers around the world, including the top TOP500 platforms. The session will discuss the InfiniBand In-Network Computing technology and performance results, as well as view to future roadmap.”

Video: Three Perspectives on Message Passing

Robert Harrison from Brookhaven gave this talk at the MVAPICH User Group. “MADNESS, TESSE/EPEXA, and MolSSI are three quite different large and long-lived projects that provide different perspectives and driving needs for the future of message passing. All three of these projects employ MPI and have a vested interest in computation at all scales, spanning the classroom to future exascale systems.”

Containerized Convergence of Big Data and Big Compute

Christian Kniep gave this talk at HPCKP’19. “This talk will dissect the convergence by refreshing the audiences’ memory on what containerization is about, segueing into why AI/ML workloads are leading to fully fledged HPC applications eventually and how this will inform the way forward. In conclusion Christian will discuss the three main challenges `Hardware Access`, `Data Access` and `Distributed Computing` in container technology and how they can be tackled by the power of open source, while focusing on the first.”

Frontera: The Next Generation NSF HPC Resource, and Why HPC Still isn’t the Cloud

Dan Stanzione from TACC gave this talk at the MVAPICH User Group. “In this talk, I will describe the main components of the award: the Phase 1 system, “Frontera”, the plans for facility operations and scientific support for the next five years, and the plans to design a Phase 2 system in the mid-2020s to be the NSF Leadership system for the latter half of the decade, with capabilities 10x beyond Frontera. The talk will also discuss the key role MVAPICH and Infiniband play in the project, and why the workload for HPC still can’t fit effectively on the cloud without advanced networking support.”

Intel Talks at Hot Chips gear up for “AI Everywhere”

Today at Hot Chips 2019, Intel revealed new details of upcoming high-performance AI accelerators: Intel Nervana neural network processors, with the NNP-T for training and the NNP-I for inference. Intel engineers also presented technical details on hybrid chip packaging technology, Intel Optane DC persistent memory and chiplet technology for optical I/O. InsideHPC has got all the details, here, all in one place.
