High Performance Computing (HPC)
The HPC service consists of two computing clusters which are located in Zurich (Brutus, available until the end of 2016) and Lugano (Euler). In total 50,000 processor cores are available for scientific calculations. The two clusters have high-speed networks (56 Gb/s InfiniBand and 10 GB/s ethernet) with storage and parallel file systems (Lustre, Panasas). Calculations (jobs) must be started using the login nodes from the batch system (LSF). Frequently used scientific software packages and compilers are centrally installed.
Numerical processes in science often require very high computing power. This computing power is required to perform calculations in large numbers independently of each other (capacity computing) to use a large number of processors in parallel, or very large main memory (capability computing or to combine both methods). The HPC service provides users with computing capacity and basic software environment to perform such calculations. It should be noted that the HPC environment is different from a normal desktop system, in particular, there is no graphical interface. Shareholder will have the opportunity to process thousands of computing jobs per month and use several hundred computing cores in parallel. For the latter, program code is necessary, which was written for parallel processing and on appropriate programming acess libraries (e.g. MPI, OpenMP).
A limited basic function is available to all ETH members free of charge (guest user). Euler accounts are automatically created when a users logs into their NETHZ account via SSH for the first time on euler.ethz.ch. Guest accounts are no longer available on Brutus.
To use more than two computer nodes simultaneously, guaranteed processing power and dedicated storage the organizational unit (department, group or institute) must purchase a shareholder in the computer system. Shareholders receive a guaranteed average computing power, a defined area in the storage system and qualified support according to their financial contribution. Shareholders can also purchase additional storage space. For purchasing as a shareholder please contact Olivier Byrde via .
