Missing Features
Comprehensive software stack
We have provided a basic software stack that should satisfy most users, but some software packages or libraries you require may not be present. If that is the case, let us know by reporting as a "Problem on computing" through the ECMWF Support Portal mentioning "Atos HPCF" in the summary.
End of job information
A basic report is provided at the end of the job with information about its execution.

Alternatively, you may use sacct to get some of the statistics from SLURM once the job has finished.
Connectivity
- SSH connections to/from VMs in Reading running ecFlow servers are not available. For more details on ecFlow usage, see HPC2020: Using ecFlow.
- Load balancing between Atos HPCF interactive login nodes is not ready yet. When implemented, an ssh connection into the main alias for the HPCF may create a session in an arbitrary login node.
Filesystems
The select/delete policy in SCRATCH has not been enforced yet.
See HPC2020: Filesystems for all the details.
ECACCESS and Time-Critical Option 1 (and 2) features
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.
Known issues
Intel MKL greater than 19.0.5: performance issues on AMD chips
