That's a good book too (i have it) but more general than the Ridgway Scott book which uses examples from Numerical Computation domains. Here is an overview of the chapters; example domains start from chapter 10 onwards - https://www.jstor.org/stable/j.ctv1ddcxfs

These sort of books are only "dated" when it comes to specific languages/frameworks/libraries. The methods/techniques are evergreen and often conceptually better explained in these older books.

For recent up to date works on HPC, the free multi-volume The Art of High Performance Computing by Victor Eijkhout can't be beat - https://news.ycombinator.com/item?id=38815334
