Article on Flash Informatique at EPFL about Free Software for HPC

Monday, December 19th, 2011

In the last number of “Flash Informatique” at EPFL you can read an article by Vittoria Rezzonico about free software for HPC.

Since the Beowulf revolution, High Performance Computing (HPC) has been taken over not only by clusters built from commodity hardware, but also by free software. Starting from the operating system, up to the specific scientific software, supercomputers (even the most powerful in the world) sport all kind of free software.

Interview with Vittoria Rezzonico, Computational Sciences and Engineering Coordinator at EPFL

Monday, December 12th, 2011

Vittoria Rezzonico is the new Computational Sciences and Engineering Coordinator at EPFL. In this function Vittoria has become the reference person at EPFL for HPC issues and she is coordinating the deployment of shared HPC systems at the university.

In his function Vittoria meets on a regular basis the researchers of EPFL to learn their needs in supercomputing. Starting with this information she advises them about where they can best get the needed resources. These can be internal pooled HPC systems at EPFL but also external resources like CADMOS, CSCS or Vital-IT.

In the past research groups at EPFL were each running own suppurate clusters. This made very difficult to effectively use the building infrastructure. In addition some clusters were getting old, thus heaving high running costs (electricity, cooling, space) in proportion to the provided FLOPs. Professors have to pay for the compute nodes. The costs like high-performance connectivity and storage, system management, electricity and, cooling are taken over by EPFL.

Previously Vittoria was working at the School of Basic Sciences as facility manager for the data center and as a cluster administrator. Vittoria decided to apply for this new position to broaden her horizons.

We wish Vittoria a great success in her new function and thanks for her big support of hpc-ch activities.

CSCS User Day Poster Session – Videos on “Global Climate Modeling” and ““Wind Energy Studies”

Thursday, October 27th, 2011

The CSCS User Day brought together around 60 users in Lucerne on 23 September. Exciting scientific lectures, lively two-minute personal poster presentations by scientists and discussions were the order of the day in Lucerne .

In the next weeks we will present some videos of researchers explaining their posters and the videos of the three invited talks: Jeroen Tromp (Princeton, USA), Lucio Mayer (University of Zurich), Rustam Khaliullin (University of Zurich).

We start with Dr. Doris Folini,  senior researcher in the Institute of Atmospheric and Climate Science at ETH Zurich presenting the poster on “Global climate modeling at C2SM/ETH: motivation, tool and highlights”.

Yu-Ting Wu, PhD student in the Wind Engineering and Renewable Energy Laboratory  (WIRE) of  Professor Fernando Porte-Agel at EPF Lausanne presented  a poster on “A large-eddy simulation framework for wind energy studies”.

EPFL Launched ecocloud Consortium to Tackle Electricity Demands of Internet Data Processing Centers

Tuesday, May 31st, 2011

EPF Lausanne announced today the launch of the ecocloud consortium. The consortium brings several EPFL laboratories together to tackle the skyrocketing electricity demands of Internet data processing centers.

At EPFL, twelve laboratories are joining their expertise to form the ecocloud consortium, launched today in a special event at the Rolex Learning Center. Its objective is to work on reducing the amount of energy these centers consume.

Ecocloud´s research is organized around three axes: data, energy and intelligence. Promising ideas are already being explored; for example, research into directly cooling processors as a function of the jobs they are doing at a given time; and constructing a “vertical” system in which the memory sits above the processor, in order to increase and optimize the flow of information between them.

As evidence of the economic potential of its research, ecocloud already has several industry partners: Credit Suisse, HP, IBM, Microsoft, Nokia, Oracle, Swisscom and Intel. The consortium has secured additional funding from programs in Switzerland (nano-tera) and Europe. “Thanks to the support and expertise of our scientists, we are in a position to become a recognized center of excellence at the European level in the domain of Cloud Computing,” says Babak Falsafi, head of EPFL´s Parallel Systems Architecture Laboratory (PARSA).
