Review for: Large-scale Scientific Computing in the Fight Against COVID-19

Hi,not sure if I am in the correct user interface because I cannot see the document I am commenting on. However, I have it up in a different window. My only comments are pretty minor.In the abstract, it has a lot of commas in the first sentence. Perhaps replace the last comma with a hyphen at the end?
