Hardware

Currently the ATLAS Black Forest Grid consists of a small number of infrastructure servers, 250 worker nodes and seven (amount customizable) user-interfaces. The user-interfaces are meant for interactive use, in particular compiling and debugging software, which is going to be run on the cluster. The worker nodes are accessible through the batch system of user interfaces nodes. In total there are 5044 cores (hyperthreaded where applicable) available. (Properties / constraint is not enabled yet)
