Applications

Eric Gedenk reports on the OLCF site on a team of researchers from Brown University and ETH Zurich, the Universita da Svizzera Italiana (USI) and Consiglio Nazionale delle Ricerche (CNR) are using America's largest, most powerful supercomputer to help understand and fight diseases affecting some of the body's smallest building blocks. Researcher Yu-Hang Tang and his collaborators exploited Titan's GPU accelerators and developed uDeviceX, a GPU-driven particle solver - an important part of the team's code that helps plot individual particles in the simulation. Tang's new solver showed a forty-five-fold decrease in time to solution compared with competing state-of-the-art methods. Gedenk continues: "Moreover, Tang's extensive work with GPUs has led to the team's newest computational tool - the multiscale universal interface (MUI). The team's research interests require a variety of different codes, with certain computing architectures working better with certain codes and different architectures benefitting other codes. It also gives the team freedom to focus specific solvers for different scales simultaneously." Read further...

Industry news

In the OH-Tech blog, Alan Chalker from the Ohio Supercomputer Center published a report on the sixth annual International Industrial Supercomputing Workshop in Cleveland. Hosted jointly by Pankaj Shah, executive director of the Ohio Supercomputer Center, and Suzy Tichenor, of the Oak Ridge National Laboratory, the IISW was held in conjunction with the 2015 Internet2 Technology Exchange. The workshop is a venue for invited attendees to meet, network and share best practices in order to improve collaboration and help expand industrial use of HPC. Keynote speaker was Tom Lange, who retired in January as Procter & Gamble's director for Modeling and Simulation in Corporate R&D. "Lange's consistent message is one we embrace and it goes hand-in-hand with what many from within IISW believe: That supercomputing offers industry a critical competitive edge when harnessed. The benefits - traditionally used to pursue scientific objectives by governments and academia - help industry by providing resources and expertise in a more visual and cost-effective way", writes Alan Chalker.

Focus on Europe

The first OpenMP conference in Aachen, last month was a big success. For those who were not able to attend, there is now a menu of 15 interviews to choose from, shot at the conference. Matthijs van Waveren interviewed Tim Mattson of Intel about new architectures and OpenMP; Mark Bull EPCC about an interesting application of hybrid MPI/OpenMP/SIMD programming; William Tang of Princeton University discusses use of OpenMP in extreme software applications for fusion energy; James Beyer of NVIDIA talks about OpenMP and OpenACC; and there are many more speaker interviews available.

During the Docker workshop at the ISC Cloud & Big Data Conference in Frankfurt, Holger Gantikow from Science and Computing gave an in-depth introduction into Docker. His presentation was split into 4 parts. Part I: What is Docker?; Part II: Why Docker matters; Part III: A little bit of security; Part IV: Getting started. Read further...
During the Docker Workshop at ISC Cloud & Big Data, Frankfurt, Christian Kniep, QNIB Solutions/Gaikai presented "Docker & Software Stacks". Kniep described and demonstrated how to use QNIBTerminal, a tool to spawn HPC cluster stack using docker images. QNIBTerminal ties together service discovery, DNS interface, health check, and a key/value store. Another procect Kniep is involved in is Docker-ELK. This is a dockerfile creating ELK services (Elasticsearch/Logstash/Kibana). Read further...
