CSCS User Day Poster Session – Videos on “Engineering mechanosensitive interaction” and “Main Factor Affecting the Climate in Glacial States”

Monday, October 31st, 2011

We continue with our series of scientists explaining their posters presented at CSCS User Day.

Samuel Hertig is a PhD student in the Biologically Oriented Materials Laboratory of ETH Zurich lead by Professor Viola Vogel. Samuel won the CSCS User Day 2011 Best Poster Award with the poster on “Engineering mechanosensitive interactions: Lessons learned from bacterial adhesins“.

Dr. Dominik Hofer, is a post-doc researcher at the University of Bern and collaborates in the project of Professor Christoph Raible. He presents his poster on “The impacts of the continental ice sheets and the external forcing for the last glacial maximum and 65kyr BP on atmospheric dynamics and precipitation in Europe”.

HPC @ University of Bern: ubelix – Uni BErn LInuX cluster

Friday, January 22nd, 2010

Purpose
This Grid HPC infrastructure is primarily designed to support the researchers at the Campus. They should use their time doing research and not be bothered by deploying a Grid HPC infrastructure.

Some facts

first Linux Cluster was installed in 2001 (1 master and 32 single core nodes)
continuously expanded to ~1000 cores in >200 nodes today
Dual- and quadcore worker nodes
Mostly Opterons, increasing # of Intels (Nehalem)
several suppliers (mostly SUN, but currently also IBM and some Dell)
< 100kW
Gentoo Linux www.gentoo.org
Kernel 2.6.22/2.6.27
2TB memory, 50TB disk
Lustre filesystem: 1.8.1
Sun Grid Engine 6.2
Gb Switch
Currently no Infiniband Switch

Internal (private) network

TCP/IP
Stackable Switches (~40Gbs)
?normal“ Gigabit Ethernet on the worker nodes
10GE Ethernet for high throughput servers

Lustre@ubelix

Application portfolio (local users)

HE Physics
Astronomy
Computational and Molecular Population Genetics Lab
Space Research Physics
Computer Vision and Artificial Intelligence
Chemistry and Biochemistry
…

Applications from remote (SMSCG)

ATLAS: high energy physics application developed for the LHC experiment at CERN
RSA768: cryptographic application
NAMD and GROMACS: biochemistry applications
GAMESS: biochemistry application (work in progress)
…

Other clusters @ UniBE

The LHEP UNIBE Atlas T3 2009 – A ROCKS Cluster with ~200 cores (Sun Fire X2200 IU dual quad cores) and ~50 TB on CentOS. Located in same room as ID UNIBE clusgter. Mainly serves local and remote ATLAS scientists. Backfilled with remote users and applications. Speciality: Access only via ARC clients, i.e. remote and local users habe the same interface. http://ce.lhep.unibe.ch
Theoretical Physics (~200 cores, with interconnect)
Climate Physics (~100 cores)
Space Physics (~100 cores)
Chemistry (~100 cores, with interconnect)
Computational and Molecular Population Genetics (~60 cores)
