The goal of this document is to describe the best way of ensuring maximum resourceusage, while taking into account certain aspects, like sustainability, of data processingpipelines in ODISSEE. In particular, we present the current status of platforms Allen (LHCb)and SKAO (including precursors). We describe possible programming models and toolsin order to achieve such performance and finally we describe on which hardwareplatforms we aim to deploy such software stacks. This report places the relevant pieces(use cases, end users, tools & programming models and hardware) in such a way thatit depicts the project’s big picture and so facilitates proper technical decisions whichshall lead to the fulfilment of project ODISSEE goals.
