New Intel® Omni-Path White Paper Details Technology Improvements

Rob Farber

The Intel Omni-Path Architecture (Intel® OPA) whitepaper goes through the multitude of improvements that Intel OPA technology provides to the HPC community. In particular, HPC readers will appreciate how collective operations can be optimized based on message size, collective communicator size and topology using the point-to-point send and receive primitives.

Edison Supercomputer Creates 3D Map of Adolescent Universe

Machine learning is the science of getting computers to act without being explicitly programmed. The new R2D3 Blog offers an instructive Visual Introduction to Machine Learning.

GENCI to Collaborate with IBM in Race to Exascale

world

Today GENCI announced a collaboration with IBM aimed at speeding up the path to exascale computing. “The collaboration, planned to run for at least 18 months, focuses on readying complex scientific applications for systems under development expected to achieve more than 100 petaflops, a solid step forward on the path to exascale. Working closely with supercomputing experts from IBM, GENCI will have access to some of the most advanced high performance computing technologies stemming from the rapidly expanding OpenPOWER ecosystem.”

Accelerating Science with SciDB from NERSC

Over at NERSC, Linda Vu writes that the SciDB open source database system is a powerful tool for helping scientists wrangle Big Data. “SciDB is an open source database system designed to store and analyze extremely large array-structured data—like pictures from light sources and telescopes, time-series data collected from sensors, spectral data produced by spectrometers and spectrographs, and graph-like structures that illustrate relationships between entities.”

From Grand Challenges to Critical Workflows

Grand-Challenge-Blog-Part1

Geert Wenes writes in the Cray Blog that the next generation of Grand Challenges will focus on critical workflows for Exascale. “For every historical HPC grand challenge application, there is now a critical dependency on a series of other processing and analysis steps, data movement and communications that goes well beyond the pre- and post-processing of yore. It is iterative, sometimes synchronous (in situ) and generally more on an equal footing with the “main” application.”

SDSC Gets One-year Extension for Gordon Supercomputer

The National Science Foundation has awarded the San Diego Supercomputer Center (SDSC) a one-year extension to continue operating its Gordon supercomputer, providing continued access to the cluster for a wide range of researchers with data-intensive projects.

IBTA Publishes RoCE Interoperability List from Plugfest

RoCE

Today the InfiniBand Trade Association (IBTA) announced the completion of the first Plugfest for RDMA over Converged Ethernet (RoCE) solutions and the publication of the RoCE Interoperability List on the IBTA website. Fifteen member companies participated, bringing their RoCE adapters, cables and switches for testing to the event. Products that successfully passed the testing have been added to the RoCE Interoperability List.
