Hi Kyle,

I seem to recall reading a book of that title.  If my memory serves,  
it was an excellent book. ;)  Alas, pretty much anything written  
about machines of 10 years ago is going to be very out of date:    
when I wrote the book, the teraflops barrier had yet to be broken.    
On the other hand I think the material on MPI is still useful.

Best wishes,
Peter Pacheco
