The European Centre for Medium-Range Weather Forecasts (ECMWF) intends to issue an Invitation to Tender (ITT) for a new High-Performance Computing Facility (HPCF). The procurement is intended to meet ECMWF’s high perform…
ance computing requirements in two areas. Firstly it should provide a highly-available computational backbone for ECMWF’s time-sensitive numerical weather prediction using both physics and data-driven models. Secondly it should provide resources specifically optimised for the training of machine lea
rning models. The requirement for a highly-available production service should be met by the phased installation during 2027 of several new HPC clusters in the ECMWF Data Centre in Bologna. The resources for training machine learning models
