* Description: different loads on seperate execution entities, indiactes
* badly configured application, e.g. CPU internal structures were not taken into account
* badly distributed workload on parallel entities
* singular work, e.g. I/O or other hardware specific operations
* Citerion:
* the minimum, median and maximum of a specific metric is not within a specifc distance from each other. Metrics can be runtime, cpu-time or other ressource specific rates
* parallel execution entities are sychronized at some point in the computation
