Before and After the Vectorization

In this part of the book, most elementary features of vector processing are introduced. There axe many other vectorization techniques and vectorized algorithms, which will be much enough to make one thick book. Even if your program is completely vectorized and almost all machine time is spent on vector pipelines, it does not alway mean the best performance. There may be waiting time for the data or results and you may get better performance if the waste can be removed. Some pipelines may not be used at all and you can simulate faster if you change the program or the algorithm so that all the pipelines may work. Further things will be found in the manuals of your vector computers, although they seem not to be user friendly. But now you have already understood the vector computer roughly and it will not be difficult to make out further details in the manuals.
