Slidecast: UCX – Unified Communication X Framework

ucx

In this slidecast, Pavel Shamis from ORNL and Gilad Shainer from Mellanox announce the UCX Unified Communication X Framework. “UCX is a collaboration between industry, laboratories, and academia to create an open-source production grade communication framework for data centric and HPC applications.”

PNNL Looks at Undervolting to Meet Exascale Goals

Figure depicting the general constraints at scale for building exascale architectures. The undervolting component (shown in 4) is part of ongoing work that PNNL’s HPC group and their collaborators are conducting in the effort to build highly resilient and energy-efficient HPC systems.

PNNL researchers are using supercomputers to take on two of the main challenges of exascale: energy efficiency and resiliency. Their simulations show that dynamic voltage scaling, also known as undervolting, can reduce power consumption and leverage existing mainstream resilience techniques at scale for improving system failure rates.

HPC Market Update from Intersect360 Research

addison2

“The drive toward exascale computing, a renewed emphasis on data-centric processing, energy efficiency concerns, and the limitations of memory and I/O performance are all working to reshape High Performance Computing platforms. Many-core accelerators, flash storage, 3D memory, integrated networking, and optical interconnects are just some of the technologies propelling these future architectures. In concert with those developments, the HPC vendor landscape has been churning in response to broader market forces, and these events are going to drive some interesting changes in the coming year.”

Video: High-Performance and Scalable Designs of Programming Models for Exascale Systems

DK Panda, Ohio State University

“This talk will focus on programming models and their designs for upcoming exascale systems with millions of processors and accelerators. Current status and future trends of MPI and PGAS (UPC and OpenSHMEM) programming models will be presented. We will discuss challenges in designing runtime environments for these programming models by taking into account support for multi-core, high-performance networks, GPGPUs, Intel MIC, scalable collectives (multi-core-aware, topology-aware, and power-aware), non-blocking collectives using Offload framework, one-sided RMA operations, schemes and architectures for fault-tolerance/fault-resilience.”
