While the availability of virtual infrastructure to run ecFlow servers remains limited, you may start your ecFlow servers in the interim HPCF dedicated node to be able to run your suites, as detailed in HPC2020: Using ecFlow. However, keep in mind the new model when migrating or designing your solution. |
At a later stage, those ecFlow servers will need to be moved to dedicated Virtual Machines outside the HPCF. Unlike the ones for standard users, these ones will be completely independent from the HPCF with a local user account and no shared HOME or any other filesystems. You will need to transfer and keep in sync all the needed suite files such as tasks and headers onto the ecflow server.
You may also need to run a log server on the HPCF depending on where you run your ecflowUI if you need to inspect the job outputs.
For job submission and management, those ecflow VMs will come with "troika", the tool used in production at ECMWF to manage the submission, kill and status query for operational jobs. This tool is currently in process of being finalised for the Atos HPCF and will be made available together with the ecflow VM service.
