Description

Supercomputer Hazel Hen, a Cray XC40-system, is at the heart of the high performance computing (HPC) system infrastructure of the HLRS. With a peak performance of 7.42 Petaflops (quadrillion floating point operations per second), Hazel Hen is one of the most powerful HPC systems in the world (position 8 of TOP500, 11/2015) and is the fastest supercomputer in the European Union. The HLRS supercomputer, which was taken into operation in October 2015, is based on the Intel® Haswell Processor and the Cray Aries network and is designed for sustained application performance and high scalability.

Tools and libraries

Access to the system is possible with ssh.

Since we don't offer shared nodes due to security and performance reasons, the minimum accounted resources include 24 cores. The listed price it per core to be comparable and normally larger resoruces are claimed for simulations.
