Hi Guillaume , Patrick,
Model V1 of Rouen evacuation, run with OpenMOLE memory = 2G, regulary crash
at ~ 5000 step because it take too much memory, for example with :
*org.openmole.core.exception.InternalProcessingError: Error for context
values in GamaTask@737261030 {oMSeed=3486222290283990033,
proba_avoid_traffic_jam_global=0.5, seed=0.6919789505538705}*
return the error :
*Caused by: org.openmole.core.exception.UserBadDataError: s"Gama raised an
exception while running the simulation (after 5043 steps)":*
* | java.lang.OutOfMemoryError: Java heap space*
Do you think it's possible to reduce the memory footprint to 2G ?
