Abstract

The ATLAS Event Filter prototype developed at the University of Alberta (the THOR project) is being used in the context of the DAQ-1 project to study issues related to the implementation of the sub-farm model using commodity components and open source software. The prototype consists of seven dual Pentium II 450 MHz machines connected via a fast Ethernet switch and will soon be upgraded to nine dual Pentium 450 MHz machines connected in a 3×3 array using Scalable Coherent Interconnect (SCI). The entire prototype is placed behind a firewall machine which serves as the control centre for the processor farm
