In this paper we study the instruction level characteristics of the
  Perfect Club programs when compiled and executed on a vector processor. 
  Using a trace driven approach we measure the degree of vectorization of the
  programs, the vector length used in operations, the operation type
  distribution, the basic block size and the balance between memory and 
  compute operations. 
  We also study the spill code introduced in the program by the compiler and the
  pressure on the dispatch unit of the vector architecture.
