The maximum execution time of one job (simulation) is two weeks. After this period, the job will be automatically cancelled. If more time is needed for a job, the user can make a separate agreement with HPC Centre.
If possible, avoid the execution of jobs locally on the login nodes. Use it only to submit a job to a queue, to compile programs, and test short jobs.
Try to indicate the necessary walltime so that other users can forecast their queue time.
If a job requires intensive disk operation (I/O), it is advised to use a local SSD disk instead of the network directory (/home/* or /home_beegfs/*). The local disk is mounted to the directory /scratch. When the job is completed, the files created in this directory should be removed by a user manually.
Evaluate the performance of parallel (MPI) jobs by using a various number of nodes/cores to select the most suitable one for your job. A larger number of cores does not always ensure faster execution of a job.
