Aggregated task view visualizing the time resolved progress of 9253 data intensive computing tasks, which have been transferred to a HPC cluster, where each task has been scheduled by Univa Grid Engine. Afterwards the results have been copied back to the original workstation. Coloured regions refer to jobs being in the same workflow state as time evolves from left to right. Slopes of interfaces between coloured regions indicate transfer rates between the respective workflow states
