Advanced ATLAS Computing Resource in Geneva for Efficient Data Analysis

The ATLAS computing facility in Geneva leverages 268 CPU cores and 180 TB of data storage to support high-performance grid batch production. With a direct 10 Gb/s line to CERN and integrated storage systems, it ensures a seamless flow of data for crucial tasks like Trigger development and commissioning. The facility is complementary to CSCS Tier 2 systems, facilitating resource sharing and maximizing job efficiency, particularly during peak demand periods. This contributes to about 1.4% of ATLAS computing operations, enhancing collaborative research efforts.

  1. ATLAS computing in Geneva • 268 CPU cores (login + batch) • 180 TB for data • the analysis facility for Geneva group • grid batch production for ATLAS • special features: • direct line to CERN at 10 Gb/s • latest software via CERN AFS • storage integrated with ATLAS data distribution systems • flow of data from CERN and from NDGFTier 1 • used for Trigger development and commissioning • complementary to CSCS Tier 2 S. Gadomski, ”ATLAS computing in GE", CHIPP, Aug 2009

  2. Added value by resource sharing local jobs come in peaks grid always has jobs little idle time, a lot of Monte Carlo done S. Gadomski, ”ATLAS computing in GE", CHIPP, Aug 2009

  3. Swiss contribution to ATLAS computing ~1.4% of ATLAS computing in 2008 S. Gadomski, ”ATLAS computing in GE", CHIPP, Aug 2009
