The purpose of the EuroHPC JU Development Access calls is to support researchers and HPC application developers by giving them the opportunity to develop, test and optimise their applications on the upcoming/available EuroHPC Pre-exascale and/or Petascale system prior to applying for an Extreme Scale and/or Regular Access. 

The EuroHPC Development call is designed for projects focusing on code and algorithm development and optimisation. As well as development of AI application methods. This can be in the context of research projects from academia or industry, or as part of large public or private funded initiatives as for instance Centres of Excellence or Competence Centres. Users will typically be allocated a small number of node hours; the allocation period is one year.
