High Performance Computing

‘High Performance Computing’ (HPC) and ‘supercomputing’ are terms referring to technologies that can be used to make the maximum computing performance available for the processing of a single technical or scientific task.

We have been active in this area since the founding of SCS (1993) and are in direct contact with the most important suppliers and users of supercomputers such as CSCS. In line with this area’s specific requirements, SCS has a great deal of experience in high-speed communication (high-bandwidth networks, low-latency communication, low-latency software stacks) and scaling hardware and software architectures for reliable operation with hundreds or even thousands of computers. To give an example: Through employing discrete event simulations, the behaviour of very large parallel supercomputers dealing with specific workloads and failure scenarios could be simulated virtually in order to identify design bottlenecks.

SCS also supports custormers/clients when it comes to improving the performance of new or existing application code, as well as facilitating their portability and performance-portability from x86-architecture CPUs to accelerator hardware such as general-purpose GPUs:

  • AI at the Edge: How artificial intelligence moves from cloud to deviceAI at the Edge: How artificial intelligence moves from cloud to device
    (Unfortunately, this presentation is currently only available in German.) In naher Zukunft wird KI zu unserem Alltag gehören. So werden selbstoptimierende Maschinen, Spracherkennung sowie diagnostizierende Medizingeräte uns täglich unterstützen. Die zugrunde liegenden Algorithmen sind extrem leistungsfähig aber auch leistungshungrig. Was steckt wirklich hinter der KI? Wie kann diese «at the edge», also eingebettet im Endgerät laufen, ...
  • Weather Forecast from the Graphics CardWeather Forecast from the Graphics Card
    Graphic Processors (GPUs) offer better performance at lower costs and energy demand compared to regular processors (CPUs). A consortium linked to the Swiss National Supercomputing Centere (CSCS) in Lugano, the Federal Office of Meteorology and Climatology MeteoSwiss, the Centre for Climate Systems Modelling (C2SM) of the ETH Zurich as well as other partners has established ...

    The weather forecast by MeteoSwiss and many other European meteorological services are based on COSMO, the numerical weather prediction system. The ‘dynamic core’ of this model was reprogrammed by SCS. This was done in co-operation with the following key partners: MeteoSwiss, ETH Zurich and the Swiss National Supercomputing Centre (CSCS) in Lugano as well as ...
