From 2023-01-18 ECMWF will enforce killing jobs if they have reached their wall time if "#SBATCH --time=" or command line option "-–time=" was provided with the job.
Alternatively ECMWF accepts jobs without "#SBATCH --time=" or command line option "-–time=" and ECMWF will instead use average runtime of previous jobs trying to bunch them using job name, job geometry and job output path.
For new jobs we will assume 24h runtime and allow another 24h grace time, allowing a new job to run for up to 48h. After the first successful run it will use the average + one standard deviation of the previous 20 successful runtimes of the job allowing the job 24h grace time.
