Following the termination of the test Atos system (TEMS) in Reading in November 2021 and a lot of work by many teams across ECMWF, we are pleased to announce the availability of the first Atos cluster, named 'aa', in Bologna, for ECMWF staff.
We invite everyone at ECMWF to start testing your personal computational activities currently running on your local desktop, on the servers (lxc, lxop, ecgate) and on the Cray HPCs (cca and ccb) onto on the first Atos system called 'aa' in Bologna(aa). To help you with this work, we have updated the Atos HPCF Documentation. We strongly encourage you to read through those pages before you start your work on this new platform.
The prepIFS environment for running IFS experiments on Atos is still under development, and is not yet ready for general use. There are still some final pieces of the hardware and software configuration to be set up, and the IFS section are is busy porting and testing IFS cycles, and tuning configurations for the Atos supercomputer. A further announcement will be forthcoming where users will be invited to start running prepIFS experiments on Atos, and migrating their workflow from their workstations & the Cray supercomputer.
