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
