  If you are running your application on a system
  that has a vector processor, collecting Vector
  Usage information on your application is useful for
  determining:

  o  Where your application uses vector instructions

  o  The scalar/vector parallelism throughout your
     application

  o  How the vector processor is used

  To collect vector usage information on your
  application:

  o  Compile and link your application with the PCA
     Collector

  o  Run your application. This causes the PCA Collector
     to take control of your application. PCA diplays the
     Collector main window on your screen.

  o  From the File pull-down menu, create a data file
     into which the Collector places performance data.

  o  Choose the Vector Usage query category.

  o  Click on the specific vector usage query that you
     are interested in collecting information on.

  o  Click on Collect in the Collector main window.

  For information on displaying the results of the vector
  usage queries, refer to:

  o  The hardcopy manual, Guide to DIGITAL Performance
     and Coverage Analyzer for OpenVMS Systems

  o  The online help for the PCA Analyzer.
