ICIS recently(august 2014) acquired a new server, called Dagobert (because of its hefty price). It is a Dell R920, with quad processors (E7-4870 v2 at 2.3 Ghz) with 15 cores each (60 total) and 3 Tb RAM (1600 Mhz). A few pictures of our new server are attached. This server was bought from the Radboud Research Facilities grand to explore new research directions, achieve more relevant scientific results and cooperate with local organizations. This is the first of three phases for new equipment for ICIS. For now Dagobert is absolutely the most powerful server in our whole faculty (with a heavy 4.4 kW power supply, weight in excess of 30 kg), the next best server has only 256 Gb RAM and half the processor power.
