We thank the reviewers for their valuable and insightful comments. General Comments Single Precision (Rev 2, 3) Rev 2: The comment on the precision limitation is very worrying. Rev 3: the work only considers single precision (as mentioned in the Limitations) due the RT cores limitations We acknowledge that single precision is an inherent limitation of the RT cores and discuss the consequences to our experiments in Sec. VI-C. In practice, every particular simulation task will have a specific demand for precision and can opt for other, slower implementations of Barnes-Hut algorithm if single precision is not enough for its purposes.
