Seastar Configuration & Documentation

  • Using Seastar : PDF-version (handy for printing)
  • Using Seastar : HTML-version (handy for online reading)
    I wrote "Using Seastar" in LaTeX, this is not a language made for the web, so if would suggest using the pdf-version, even if you read it online...

Tips & tricks

  • Please note that to compile your code you may need to load the compilers e.g. using command module load ifort. To get the list of available modules you type module avail.

  • You submit the job using command qsub (e.g. qsub submit.sh). You can see the status of your current jobs using qstat. The command qstat -q lists the summary of all currently running jobs on all queues. To delete the job use qdel followed by the job number. Example submit script is located above.

  • The default quota in your home directory is only 2.5 GB. You are therefore strongly advised to run jobs from your data directory ($VSC_DATA) and not from your home directory.

  • To get the custom commands replacements (like command '..' being equivalent to 'cd ..' etc.) you should edit your .bashrc file located in your home directory. For example adding line alias ..='cd ..' and restarting the connection to Turing will make the above mentioned command '..' work.
