[Simgrid-user] SimDAG troubles

I have developed a scheduler of DAG applications using SimDAG.
Now, I am trying to use it for scheduling an application of 280 tasks on 4
hosts, but the simulation finishes without executing all tasks.
I have checked whether all tasks were correctly scheduled, and they were (I
saw the state of each task before the "SD_simulate()" call).

I have noticed that after the simulation the tasks which were not executed
either remain in  the SD_SCHEDULED state or were in the SD_IN_FIFO state.
These tasks which remain in the SD_SCHEDULED state were not executed because
they depend indirectly on those in SD_IN_FIFO state.

I do not know what to do.
Could someone help me?
