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.

New Server Room for the Faculté des Sciences de base at EPFL

Wednesday, June 23rd, 2010

In the last issue of Flash Informatique Vittoria Rezzonico is describing the new server room for the Faculté des Sciences de Base at EPFL. In this server room are also located several of the HPC systems used at EPFL.

Follow-up second hpc-ch forum on OS and Installation Methods at EPFL

Sunday, June 6th, 2010

The second hpc-ch forum on operating systems and installation methods at EPF Lausanne on May 20 has been a great success with more than 35 HPC participants.

In the morning we have been welcomed to EPFL by Vittoria Rezzonico (sysadmin and local organizer) and Jean-Claude Berney (director of the IT services). Jean-Claude pointed out the importance of HPC for EPFL and the growing infrastructure needs to run the supercomputers. He also acknowledged the importance of our community giving the possibility to exchange knowledge between peers in Switzerland.

Vittoria organized for us site visits to the technical infrastructure and computing room at EPFL. Every think was very impressive and show how complex it is today to run data centers.

In later postings we will publish the slides presented in the different technical talks.

In different visits we had also a look to the technical infrastructure and the different computer room (both very impressive).

We would like to thank Vittoria Rezzonico and all the team at EPFL for the organization and hosting us.

Here below you will find some pictures of the day.
