Migration plan
The new Atos will not only replace the current HPC service provided by the Cray XC40 systems, but also all Linux servers, e.g. ecgate.
All users are invited to migrate their workload to the Atos at their earliest convenience. Before starting any migration work users are encouraged to familiarise themselves with the Atos HPCF and ECGATE services.
The Atos system, is still awaiting formal acceptance but is providing a full parallel service, reliably supporting the running of the Release Candidate Phase. As we are getting closer to the switch of the operational forecast to the Atos, expected for 18 October 2022, the support level will be heightened from the current ‘social hours’ to 24/7. From 1 November usage of the operational Atos HPC service (hpc-login) will be charged against SBU allocations. In the meantime Atos usage can already be monitored. The Atos ECS service (ecs-login) which replaces ecgate will remain free of charge.
From 1 November ecgate, the Cray HPCF, and all attached filesystems will no longer be available. The Cray HPCF will be immediately shutdown by the vendor and the decommissioning of the Reading data centre will start. Please copy all Cray and ecgate files you need to keep to the Atos before that date.
To support users with their migration we are offering Atos expert sessions. Please see the event page for more details and to register.
Indicative timeline
During the parallel run the support level will be heightened from the current ‘social hours’ to 24/7. The start of the Atos contract is currently expected for 1 November 2022. The decommissioning of the Reading data centre will start on 1 November 2022.
