This book is touching everything in the field of HPC in a superficial way. At the end, a specialist finds out that it didn't add anything new to what he already knows. In a very few pages, the authors tackle the HPC, Grid Computing, Cloud Computing, and other heavy concepts. Besides, it is full of spelling errors, the grammar is not adequate; at the end, this gives you the feeling that the authors were not willing to exert real effort when writing their book. Being a researcher in the field, sorry to say that I don't recommend this book at all to researchers.
