31 > [350.000000] (1:test@MyHost1) Finally, simulate a malleable task (a parallel execution that gets reconfigured after its start).
32 > [350.000000] (1:test@MyHost1) - Start a regular parallel execution, with both comm and computation
33 > [360.000000] (1:test@MyHost1) - After 10 seconds, 50.00% remains to be done. Change it from 3 hosts to 2 hosts only.
34 > [360.000000] (1:test@MyHost1) Let's first suspend the task.

42 > [360.500000] (1:test@MyHost1) What was already done is removed, and the load of the removed host is shared between remaining ones.
