Since 2005 the Swiss ATLAS Grid is in production. It comprises four clusters at one Tier 2 and two Tier 3 sites. About 800 heterogenous cores and 60 TB disk space are connected by a dark fibre network operated at 10 Giga bit per second. Three different operating systems are deployed. The Tier 2 cluster runs both LCG and NorduGrid middleware (ARC) while the Tier 3 clusters run only the latter. As local resource management systems both OpenPBS/Torque and Sun Grid Engine are used. In 2006 about 200 000 CPU hours of central ATLAS production were run on a smaller version of this infrastructure. Local users ran about 60 000 CPU hours for ATLAS physics studies. As end user tools ARC clients, ATLAS DQ2 software, ATLAS Ganga and a new graphical user interface are employed. With emphasis on the heterogenous solutions we report on the current and future infrastructure and usage of this part of the ATLAS grid.
