7. Lunarc web User registration System information System usage Job submission ?

8. Using clusters Log in –Use ssh, unix tools etc mkdir proj sftp/scp user@... vi/joe submit script –Submit script documentation Queue management –qsub script Transfer result files back –sftp/scp For many, this is a straightforward process, but why do we get so many questions??

9. Web portal for our clusters

10. Good knowledge about local circumstances Traditional users -> clusters -> grids User interface Grid of clusters
