Real-Time Interactive Parallel Visualization of Large-Scale Flow-Field Data

Round 1

Reviewer 1 Report

The paper relates to numerical simulations using Computational Fluid Dynamics, large-scale grids for discretized solutions, large-scale  flow field data for real-time interactive visualization. The article presents novel strategies for data partitioning based on grid segmentation, and next reconstructing subgrids within each process utilizing coordinate mapping algorithm to map global coordinates to local process coordinates. In addition, introducing a real-time interactive  methods for large-scale flow fields is made. The proposed method leverages the system architecture of high-speed interconnection among compute nodes in a cluster environment and low-speed interconnection between service nodes and rendering nodes. The authors presents are very interesting results on efficient data access and real-time interactive control in largescale parallel visualization of flow fields. Thus, their strategy allows for coordinated management of parallel rendering and synchronized rendering methods. The experimental results on typical flow field data are then demonstrated. They show improvement of the loading speed of millions of grid-level data surpassing ParaView’s performance of 1.5 times.

I have a few comments:

1.The Results and Discussion section should divided into two sections so that a broader discussion of various possible and already implemented variants of network solutions and cell addresses could be presented in Discussion.

2. The discussion should point not only to the advantages, but also to show diversified potential places for further analysis and improvement of the key parameters.

Reviewer 2 Report

In their manuscript titled 'Real-time Interactive Parallel Visualization of Large-scale Flow Field Data' the authors propose a data partitioning strategy based on grid segmentation and design job management, data communication, and human-machine real-time interactive coordination methods. These steps gradually achieve real-time interactive exploration of large-scale flow field data. To evaluate the methods experiments were designed and conducted. The experimental results verify the effectiveness of the proposed methods.

Dear Reviewers and Editors:

Greetings!

First of all, thank you very much for taking time out of your busy schedule to read and revise my article. You gave me a lot of useful suggestions on the formatting of my paper. It has played a very important role in improving the quality of my paper.I have carefully studied the reviewers' comments and have carefully revised my paper according to the following suggestions.

The revisions are as follows:

(A) I added spaces to all the places you mentioned that were missing spaces.

(B) I added explanations of “MBR” and “MPI” in the paper, and changed “3G data may only have 1 part” to “A single part occupies 3GB of storage space.”

(C) I changed all the italic parts of the formulas in the paper, including inline and block-level formulas.

(D) I changed the positions of “(a)”, “(b)”, and “(c)” in the caption of Figure 3.

(E) I added “as demonstrated in expression (5)”, and swapped the positions of “where” and expression 5.

(F) Actually, the color I used in Figure 6 was Blanched Almond, so I changed yellow to Blanched Almond in the caption of Figure 3.

Finally, I would like to thank you again for your guidance and for reviewing and revising my paper again. I hope that with your guidance I can complete this excellent paper and I sincerely hope that my paper will be published in your journal.

Thank you very much for your attention to our paper.
