-// Vector-vector add benchmark
-//--------------------------------------------------------------------------
-// Author  : Andrew Waterman
-// TA      : Christopher Celio
-// Student : Benjamin Han
-//
-// This benchmark adds two vectors and writes the results to a
-// third vector. The input data (and reference data) should be
-// generated using the vvadd_gendata.pl perl script and dumped
-// to a file named dataset.h 
-
-// to print out arrays, etc.
