Conversion Notes

Pipeline parallelism in server jobs can either be achieved by manually inserting InterProcess stages or enabling Inter Process Communication in the job properties. Enabling Inter Process Communication in the job properties acts the same as if you inserted inter Process Communication stages between every stage.
