Resource usage#

Compute resources#

Warning

No compute loads, or long running processing should be run on the front-end node.
The front-end is both login and service node and this can impact overall usage.

Slurm scheduling is for the moment of type "first come, first served".
To be converted to fair share.

Storage resources#

  • /home should be used for small personal files, small analysis codes
  • /software is dedicated for software frameworks (locally compiled)
  • each user have an symbolic link $HOME/data pointing to /data/data_${USER} pointing to a much larger storage area

  • for requirements over 1TB, a request should be sent to administrator for creation of a personal directory in /data{2..7}

    Institute management approval required

    For data usage for more than 1 TB a request to institute management is required. First step is to send an email to institute director with cc to issaf AT spacescience DOT ro then more information will follow in subsequent e-mails.
