Dear authors

Moreover, I have some comments.

Regarding the content:
* I have a question on Fig. 21.
If I had connected all symbols with the same dx (not the same order as done here) in order to show the dependence of runtime on order, I would have expect to see monotonically decreasing curves. Is the numerical time step fixed?
For dx=2m for instance, runtime increases slightly up to order 8, but the the order 10 simulation is faster.
So the general finding on p24l16 is not really correct.
Could you elaborate on this and modify the manuscript accordingly.

* If you want you can include the alternative verification approach proposed by the reviewer concerning the Poisson equation. I agree with the reviewer, that Fig.20 is no formal verification, however I think that main intent of the new application examples is to show the versatility of DeVito. In any case, future DeVito users have to take care, that for their specific problem, DeVito produces reliable solutions.

Regarding language etc:
* p13l8: "on its library Revolve", what does "its" refer to?

* You sometimes miss the parentheses around the citations, e.g. p2l22, p3l33 or opposite way p20l20

* I spotted several typos:
p2l29, p3l3, p8l15, p12l10: Fig., p15l21, p17l11, p18l12: remove "we"?, p20l4 (10): missing O?, p20l8: "the PDE solve part"?, p22l5 "corresponds to" = "consistent with"?, p27l13
This list is quite long and probably not complete, hence I expect that you go over the whole manuscript to find further typos.

* What about the Witte-manuscript ".. Part 3 Optimization". Has it been accepted in the meantime? The provided URL does not look like a link that will live.

Best wishes,
Simon Unterstraßer

Short summary

This paper presents Devito, a Python-based software. The aim of this software is to provide a high-level simple interface to users for the description and discretization of the mathematical definition of the physics. This research initially started as an attempt to improve research time, portability, and performance in exploration geophysics. We present the latest version of the software that is already making an impact in academics and industry.
