Instead of removing + dependencies when a task is done, a counter is decreased. This way, + it is always possible to reach ancestors thanks to the + SD_taks_get_parents function (even after the end of the simulation.) + * Change the level of some logs in sd_global from INFO to VERB. The + corresponding tests are now less verbose + * Change the return type of SD_Simulate from (SD_task_t*) into + xbt_dynar_t. This function was in handling a dynar internally and + converted it into a NULL terminated array for historical reasons. + * Rename the SD_READY (all dependencies are satisfied and task is + scheduled) state in SD_RUNNABLE and define a new SD_SCHEDULABLE (all + dependencies are satisfied) state. + This prevents a confusion between the notion of "ready to schedule" + (SD_SCHEDULABLE) used in DAG scheduling and that of "ready to be + simulated" (SD_RUNNABLE) used by the simulation kernel. + * Add an example that scheduling a DAX on an heterogeneous platform + using a Min-Min strategy + * new function SD_dotload(char*) to load a DAG described in dot + format.
