General rules

Please keep in mind the following rules:

  1. Any computations launched on the access host will be killed without notice. The access host should only be used to prepare input files and submitting jobs to the scheduler. Since transferring large quantities of data may cause significant load on the access host, it is recommended to allocate a computing node for this purpose (in interactive mode, e.g. srun -p plgrid -A grant_id -n 1 --pty /bin/bash -l).

  2. Compiling applications - this should be performed on a computing node, not on the access host (in interactive mode, e.g. srun -p plgrid -A grant_id -n 1 --pty /bin/bash -l).

  3. Computations which are out of scope of the submitted research agenda or which consume a large fraction of the cluster's resources will be killed without notice.
  4. Working datasets and intermediate results should be stored and processed in the Lustre filesystem available under $SCRATCH.
  5. Computations should not make use of the /tmp directory to store temporary data - instead, please use directories referenced by $SCRATCH or $TMPDIR.
  6. The access host imposes a memory limit for all processes belonging to the current user. Exceeding this limit will cause the offending process to be automatically killed.
