The jobs can be submitted to the CERIT-SC computing infrastructure both via the CERIT-SC frontend as well as MetaCentrum frontends:

• Using the CERIT-SC frontend - once logged on the zuphux.cerit-sc.cz frontend (using the SSH protocol), the jobs are submitted in a common way using the qsub command:
  
  $ ssh username@zuphux.cerit-sc.cz
  Password: <enter META password>

  $ qsub  <job's/nodes' properties>  <job script>

   

  Note: To access the frontend using Kerberos v5 tickets, please, add the following lines to the section "domain_realm" of your /etc/krb5.conf file (alternatively, download the new /etc/krb5.conf file from MetaCentrum site):

      [domain_realm]

      ...

      .cerit-sc.cz = ICS.MUNI.CZ
• Using MetaCentrum frontends - when submitting a job via any of the MetaCentrum frontends (list of frontends and log-in methods), there has to be the wagap.cerit-sc.cz server (the CERIT-SC scheduling server) explicitly specified. This specification is performed via the "-q" option in the following way:
  
     $ ssh username@skirit.ics.muni.cz    # or any of the other frontends
     Password: <enter META password>

     $ qsub -q @wagap-pro.cerit-sc.cz  <job's/nodes' properties>  <job script>

Note: If you use SSH keys when accessing the infrastructure, it is necessary to obtain the Kerberos credentials via the $ kinit command before the infrastructure could be properly used.

Accessing machines From Windows

You need an application which emulates terminal with ssh client to access MetaCentrum machines. We recommend these applications:

• PuTTY
• WinSCP
