Gauss Centre for Supercomputing (GCS) e.V.

Their core work

GCS is the alliance of Germany's three national supercomputing centres (JSC, HLRS, LRZ), providing the highest-tier HPC infrastructure and services in Europe. Within H2020, GCS focuses on operating and advancing the pan-European PRACE research infrastructure — delivering compute time, training, and application support to scientists and increasingly to industry users. They also play a key role in building national HPC competence centres that bridge the gap between supercomputing capabilities and real-world adoption by businesses and public institutions.

What they specialise in

How they've shifted over time

GCS's early H2020 involvement (2015-2019) was purely infrastructure-focused through the PRACE implementation phases — running and upgrading Europe's top-tier supercomputers for the research community. From 2020 onward, a clear shift emerged toward competence building, industry engagement, and business development through EUROCC and CASTIEL. This reflects the broader European push to make HPC accessible beyond academia and into SMEs and industrial applications.

GCS is moving from being a pure infrastructure provider toward becoming a bridge between supercomputing capabilities and industrial users, making them increasingly relevant for companies seeking HPC-powered solutions.

How they like to work

GCS operates exclusively as a participant, never as coordinator — consistent with their role as a national infrastructure body contributing to large European initiatives led by PRACE or EuroHPC governance structures. They work in very large consortia (131 unique partners across 34 countries), which reflects the pan-European scope of HPC infrastructure projects rather than selective partnering. Working with GCS means accessing a well-connected node in Europe's supercomputing ecosystem, but expect them to contribute infrastructure and expertise rather than drive project management.

GCS has collaborated with 131 unique partners across 34 countries, making them one of the most broadly connected HPC organizations in Europe. This extensive network stems from the PRACE and EuroHPC initiatives, which by design include nearly every EU member state's computing centres and research institutions.

What sets them apart

GCS represents Germany's combined supercomputing power — the country's three flagship centres under one umbrella — giving it a weight and resource base that few individual HPC centres can match. Their dual role as both infrastructure operator and competence builder means they can offer not just compute time but also training, application porting, and business readiness support. For any consortium needing serious HPC muscle backed by Europe's largest national supercomputing alliance, GCS is a natural partner.
