This is the User guide for the Atos Sequana XH2000 HPCF, installed in ECMWF's data centre in Bologna. This platform provides both the HPCF (AA, AB, AC, AD complexes) and ECGATE services (ECS), which in the past had been on separate platforms.
Below you will find some basic information on the different parts of the system. Pleaseclick on the headers or links to get all the details for the given topic.
We are thrilled to announce the general availability of the new JupyterHub service at ECMWF, a new way of accessing computing resources at ECMWF in an interactive and modern way. With JupyterHub you can now spin up your JupyterLab sessions on multiple backends including HPCF and ECS, leveraging the computational resources available at ECMWF without leaving your browser.
ECMWF scheduled a network system session to be held on Wednesday 13 March 2024 which impacted work on the Atos HPC. The session lasted for 4.5 hours from 12:00 UTC to 16:30 UTC.
During the session, there was NO login access to hpc-login and NO user batch jobs submitted from hpc-login or via hpc-batch could run. Batch jobs submitted before the session which were not expected to complete before the sessions started were queued until after the session finished. Time-Critical Option 1 and 2 workloads were not affected and continued to run during the session.
