Back to [[en:bu-metacentrum-vyuziti|the Institute of Botany & MetaCentrum, usage of the computing resources]] and see also [[en:prace|work on the cluster]].

====== Access to the computing cluster of IBOT for employees and collaborators ======

  - Complete [[https://metavo.metacentrum.cz/en/application/|the application for the MetaCentrum]] (you can register under any organization, not solely IBOT).
  - Join the **ibot** group by contacting the [[en:spravci-podpora|cluster’s administrator]]. Membership of this group is not mandatory for using the computing resources, but grants a higher priority.
  - It is recommended that computational tasks are prepared on the [[https://docs.metacentrum.cz/basics/concepts/#frontends-storages-homes|frontend]] node ''tilia.ibot.cas.cz'' (alias ''tilia.metacentrum.cz''), although this is not a requirement.
  - Data can be stored on the [[en:datove-uloziste|Průhonice data storage]] (again not a requirement) at ''/storage/pruhonice1-ibot/''.
  - At submission to the computing queue, by adding to the ''qsub'' command the ''-q ibot'' parameter, the analysis will be carried on our cluster, e.g. ''qsub -l walltime=1:0:0 -q ibot -l select=1:ncpus=1:mem=1gb:scratch_local=1gb -m abe script.sh''.

Employees and students from other organizations can submit tasks and run [[https://docs.metacentrum.cz/software/modules/|any applications]] on the Průhonice cluster using the same [[https://docs.metacentrum.cz/basics/concepts/|requesting commands]] and following the same [[https://docs.metacentrum.cz/access/terms/#usage-rules|rules]] as for any other node in the MetaCentrum.
