The author is one of the heavyweights in numerical linear algebra (which a lot of hpc boils down to in the end), and certainly knows his stuff. And based on some skimming of the book I did a while ago, yes, I'd say it's good. As for whether it's a good book "to get into the topic", I guess it depends on what you mean exactly. If you're a scientist who needs to write simulation code that can run on current HPC resources, congratulations , you're smack in the middle of the target demographic of this book (I guess). If not, well, maybe some other book is more appropriate.
