## What is a session?
## What is a session?
The idea behind this decomposition is to keep the *logic* of user submissions rather than the exact submission times. For example, in the image below, the workload has been split into 4 sessions following the "Arrival" delimitation approach:
Analysing the workload trace of a parallel infrastructure to identify user sessions was started by Zackay and Feitelson ([Zackay and Feitelson 2013](https://www.cs.huji.ac.il/w~feit/parsched/jsspp12/p12-zakay.pdf)).
