Lay summary

Das "Swiss Institute of Particle Physics (CHIPP)" ist  im Projekt "Large Hadron Collider  (LHC)" am CERN involviert.  Wir sind Mitglieder in den LHC Experimenten ATLAS, CMS und LHCb. Der LHC kollidiert Protonen mit Protonen. Eine erste Messrunde bei einer Schwerpunktsenergie von 7 und 8 TeV wurde im Januar 2013 erfolgreich abgeschlossen. Seit Sommer 2015 messen wir neue Daten bei einer höheren Protonen-Energie von 13 TeV.

 Die gemessenen Daten erlauben es, die Strukturen von Materie zu untersuchen, und Bedingungen zu erzeugen, wie sie im frühen Universum vorherrschten, kurz nach dem "Big Bang". Einer der bisherigen Hoehepunkte war die Entdeckung eines neuen "Higgs Teilchens", eines der fundamentalen Bestandteile des "Standard Models der Teilchenphysik".  Bei den nun höheren Energien wird ein vollständig neuer Bereich der Physik abgedeckt.

Innerhalb dieses vorliegenden SNF/FLARE Projekts nimmt die Schweiz als vertraglicher Partner des WLCG die Aufgabe eines nationalen LHC Analysezentrums wahr. Zusammen mit CSCS betreibt CHIPP am CSCS unser eigenes Grid Computing Zentrum für LHC Physik Analyse, das als sogenanntes "Tier-2 regional centre" innerhalb des WLCG weltweit vernetzt operiert. Die bisherigen Daten (> 250 PBytes) werden weltweit verteilt, und ihre Analyse wird durch die weltweite Grid Computing Infrastruktur ermoeglicht, die durch die "Worldwide LHC Computing Grid (WLCG)" Kollaboration in Zusammenarbeit mit der Europäischen EGI betrieben wird.

Dieses Analysezentrum erlaubt den Schweizer Teilchenphysikern (der Uni. Bern, Genf und Zürich, ETH Zürich, EPFL Lausanne und Paul Scherrer Institut)  Forschung auf kompetitiver Augenhöhe mit anderen Nationalitäten zu betreiben. Damit können die von den Schweizer Hochschulen im LHC investierten Mittel, sei es in Form von Hardware oder Personal, sinnvoll ausgenuetzt und optimal für Physikanalyse eingesetzt werden, um so das Potential von neuer, aufregender Physik am LHC auszuschöpfen.

Abstract

The LHC machine and the experiments have completed the long-shutdown phase 1 (LS1), and since beginning of June 2015, LHC has successfully started up again operation in the so-called "Run-2", now at the higher centre of mass energy of 13 TeV.UP to mid November 2015 already over 4 pb-1 of data have been collected.The data volume at the LHC for physics exploitation is steadily increasing, and in fall 2015 the worldwide compute resources to deal with these data has reached the level of 6 MHS06 in over half a million logical CPUs, over 330 PB of disk storage and over 250 PB of tape storage . The LHC collaborations have published a large number of physics results based on LHC data (ATLAS, CMS and LHCb combined exceed 1500 publications since the LHC startup). The Swiss particle physics community continues to be strongly committed to the LHC physics program. We are involved in the three large LHC experiments ATLAS, CMS and LHCb. As member of the international WLCG community we operate a dedicated Swiss computing facility for providing a) resources to the worldwide LHC community (as defined in an MoU), b) the means to allow performing LHC physics data analysis and simulation in Switzerland, and c) serving as a link to the national Tier-3 centres, supporting our own community. For this purpose the Swiss Institute of Particle Physics (CHIPP) and the Swiss National Supercomputing Centre (CSCS) established a dedicated compute cluster located at CSCS to function as the Swiss “Tier-2 regional centre” within the worldwide WLCG hierarchy. The resources granted on behalf of our previous requests1 have been invested in the setting up, and subsequent operation of this national “Swiss Tier-2”. Since 2005 our Tier-2 cluster has been growing and it is an integral part of the international WLCG resources for physics exploi-tation. The grants asked for in this present proposal will serve on the one hand to provide the compute resources required by the experiments for physics exploitation for the next period 2016-2017 and also to guarantee the high level of quality routine operation (in terms of reliability and availability) of an officially acknowledged national Tier-2 centre as part of WLCG, as was agreed upon by the pledges in the MoU signed by Switzerland.Operating our own Swiss Tier-2 allows us to keep the Swiss particle physics community in a competitive scientific position with respect to the other countries by maintaining a comparable level of national resources. Further, it enables the utilization and exploitation of the institutes’ investments in detector hardware and personnel by allowing appropriate analysis of LHC data, accessing the physics at the LHC, and supporting our institute-level Tier-3 analysis clusters. The work is supervised by the CHIPP Computing Board under the auspices of the Swiss Institute of Particle Physics (CHIPP). This board includes representatives from all Swiss particle physics institutes as well as CSCS. All institutes continue to rely on and strongly support the project.
