The EuroHPC Joint Undertaking (EuroHPC JU) was established with the aim of building a world-class supercomputing ecosystem and data infrastructure in Europe to support a competitive and innovative High-Performance Computing (HPC) and Big Data ecosystem. Calls opened under the EuroHPC Joint Undertaking are designed to serve research areas with significant needs in terms of computing time, data storage, and supporting resources, catering to research fields that require large-scale computing resources. Researchers from academia, industry, and the public sector can apply to these calls, and general information about the calls can be accessed on our website. Details regarding the calls, support mechanisms, access policies to systems, and other information will be provided during the EuroHPC Project Calls Information Day, which will be held online via Zoom by TÜBİTAK ULAKBİM as part of the EuroCC 2 project on January 17, 2023.
