```
public void determinePartitions(Callback c)
```
    This ends up writing out a partition for each job in the dax. It is a one 2 one mapping from the jobs in the dax to the corresponding partitions in the pdax. The ids of the partitions in pdax is same as the ids of the corresponding jobs in the dax.
