The ECACCESS web toolkit services, such as the job submission, including Time-Critical Option 1 jobs, file transfers and ectrans have not been set up yet to use the Atos HPC and ecgate ('ecs') systems.Time-Critical Option 2 users enjoy a special setup with additional redundancy in terms of filesystems to minimise the impacts of failures or planned maintenances. However, this has not been finalised yet so we would recommend not to start using these accounts until the configuration is complete

ftp.ecmwf.int service

There is no connectivity from Atos HPCF to the ftp.ecmwf.int service in Reading. We are working on the replacement service in our Bologna Datacentre. If you need to use this ftp service, you will need to use a reading platform such as ecgate, lxc or Cray HPCF as an intermediate step to push or pull data.
