HAL user spaces

You have a personal disk space (user's home): /home/${USER} or ${HOME}, fast storage hosted at Guyancourt (SSD).

You also have fast storage disk spaces, shared with the other users of the cluster, where you must create your personal directories. All these storages are fast (SSD) and hosted at Guyancourt:

  • /net/nfs/ssd1/${USER}
  • /net/nfs/ssd2/${USER}
  • /net/nfs/ssd3/${USER}

Moreover, the disk spaces of the computing centre of the IPSL (slower storage) are present at their usual mount point, currently in read only:

  • /bdd which is the data directory.
  • /data/${USER} which is your data directory hosted at Jussieu.
  • /scratchu/${USER} which is the scratch directory hosted at Jussieu.
  • /scratchx/${USER} which is the scratch directory hosted at Polytechnique.
  • /ciclad-home/${USER} which represents the home directory on ciclad HPC cluster hosted at Jussieu.
  • /climserv-home/${USER} which represents the home directory on climserv HPC cluster hosted at Polytechnique.

Warning

Remember to copy your results to the your home directory on one of the CPU clusters or on your PC because there is currently no backup on the HAL cluster.

Tip

Always consider the localisation of your data. E.g. if your data are hosted at Jussieu or Polytechnique, they are read through the network as the cluster HAL is located in Guyancourt. Copy your data on HAL's fast storages to improve their loading time.
