Technical details

CHEOPS Hardware

CHEOPS (Cologne High Efficiency Operating Platform for Science) is the HPC cluster of the University of Cologne providing scientists from North Rhine-Westphalia with a computing power of 100 Teraflop/s Peak (85.9 teraflop/s Linpack) for simulations of complex problems. In November 2010, CHEOPS ranked 90th at the list of the 500 fastest high-performance computers in the world (

It offers 817 INCA dual socket nodes in different variants as well as 24 MESCA quad socket nodes with 512 GB of RAM each. 

CHEOPS computing nodes are interconnected via an InfiniBand QDR network, which offers a bandwidth of 40 Gb/s gross at low latency. With that and the big compute nodes, CHEOPS is suitable for both highly scalable MPI applications and memory consuming SMP applications. The processors with  Intel Nehalem architecture are particularly well suited for high-performance scientific computing due to their high memory and interconnect bandwidths.

CHEOPS Software

CHEOPS carries out user jobs with the SLURM batch system. You can build your own application with the development software provided. With application software that has already been installed, you can start your jobs right away.
