Lunarc web

• User registration• System information• System usage• Job submission ?

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??

Web portal for our clusters

• Good knowledge about local circumstances

• Traditional users -> clusters -> grids

• User interface• Grid of clusters
