 **Observations**:
 
+- Across all cluster almost 50% of time is spent in "unknown" transitions, i.e.
+  there are some time slices that are related to a state transition that Google
+  says are not "typical" transitions. This is mostly due to the trace log being
+  intermittent when recording all state transitions.
+- 80% of the time spent in KILL and LOST is unknown. This is predictable, since
+  both states indicate that the job execution is not stable (in particular LOST
+  is used when the state logging itself is unstable)
+- From the absolute graph we see that the time "wasted" on non-finish terminated
+  jobs is very significant
+- Execution is the most significant task phase, followed by queuing time and
+  scheduling time ("ready" state)
+- In the absolute graph we see that a significant amount of time is spent to
+  re-schedule evicted jobs ("evicted" state)
+- Cluster A has unusually high queuing times

 **Observations**:
 
+- Most (mesasured and requested) resources are used by killed job, even more
+  than in the 2011 traces.
+- Behaviour is rather homogeneous across datacenters, with the exception of
+  cluster G where a lot of LOST-terminated tasks acquired 70% of both CPU and
+  RAM
