Mellanox Benchmarks Ceph on 100Gb Ethernet


Today Mellanox announced a set of 100Gb/s network storage performance benchmark results for Red Hat Ceph Storage and Red Hat Gluster Storage.

Time to Unite Exascale and Big Data


In this video, Dan Reed from the University of Iowa describes the era of Exascale Computing and Big Data. In a recent paper co-authored with Jack Dongarra, Reed makes an impassioned plea for hardware and software integration and cultural convergence.

Materials Discovery by Computation – a Revolution Still in the Making


“We will describe recent progress and successes obtained in predicting properties of matter by quantum simulations, and discuss algorithmic challenges in connection with the use of evolving high-performance computing architectures. We will also discuss open issues related to the validation of the approximate, first principles theories used in large-scale quantum simulations.”

HPC People on the Move – Long, Hot Summer Edition

Dr. Lewey Anton

Dr. Lewey reports on who’s jumping ship and moving on up in high performance computing.

insideBIGDATA Guide to Scientific Research

HPC Life Sciences

Daniel Gutierrez, Managing Editor, of insideBIGDATA has put together a terrific Guide to Scientific Research. The goal of this paper is to provide a road map for scientific researchers wishing to capitalize on the rapid growth of big data technology for collecting, transforming, analyzing, and visualizing large scientific data sets.

Power Usage for Coprocessors


“As the use of coprocessors increases to speedup HPC applications, it is important to understand how much additional power the coprocessors use. With various measurements and benchmarks arising to calculate the power used during the running of compute and data intensive applications, measuring the power draw from an Intel Xeon Phi coprocessor is important to understanding the best use of resources.”

New HP Apollo 4000 Systems Fulfill Booming Big Data Analytics & Object Storage Requirements


High Performance Computing and Big Data analytics touch us every day. We each rely on daily weather forecasts, banking and financial information, scientific and health analyses, and thousands of other activities that involve HPC and Big Data analysis.

Caterpillar & NCSA Expand Collaboration for Realistic Simulations


Today Caterpillar Inc. announced it will expand its collaboration with NCSA to develop more realistic simulations that can lead to improved product designs.

Video: Petascale Supercomputing for Space-Based Earth Science

Reed Patrick

“We have made substantial progress towards three transformative contributions: (1) we are the first team to formally link high-resolution astrodynamics design and coordination of space assets with their Earth science impacts within a Petascale “many-objective” global optimization framework, (2) we have successfully completed the largest Monte Carlo simulation experiment for evaluating the required satellite frequencies and coverage to maintain acceptable global forecasts of terrestrial hydrology (especially in poorer countries), and (3) we have evaluated the limitations and vulnerabilities of the full suite of current satellite precipitation missions including the recently approved Global Precipitation Measurement (GPM) mission. This work illustrates the tradeoffs and consequences of a collapse in the current portfolio of rainfall missions.

Supercomputing Flow of Carbon Emissions in Deep Oceans

A three-dimensional spatial structure of mixing in an idealized ocean simulation, computed using Lagrangian particle statistics.

A new computer model developed by scientists at LANL increases global climate simulation accuracy through a better representation of the vast eddies that swirl across hundreds of miles of open ocean.
