TEMS is a test platform where users and system administrators can prepare the migration to the final Atos systems.
This means that by nature TEMS is evolving with time, and may not be as feature complete as other production systems.
If you find any problem or any feature missing that you think should be present, and it is not listed here, please let us know by reporting as a "Problem on computing" through the ECMWF Support Portal mentioning "TEMS" in the summary.
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 "TEMS" in the summary.
End of job information
There is no report at the end of the job with information about its execution. You may use sacct to get some of the statistics from SLURM once the job has finished.
SSD disks on GPIL nodes
The GPIL nodes have local SSDs with some 950GB capacity. These have not been mounted yet, as we need to develop a service model for their use.
Known issues
Intel MKL > 19.0.5 performance issues on AMD chips
Recent versions of MKL do not use the AVX2 kernels for certain operations on non-intel chips, such as the AMD Rome on TEMS. The consequence is a significant drop in performance.
