+// This benchmark performs a 1D three element median filter. The
+// input data (and reference data) should be generated using the
+// median_gendata.pl perl script and dumped to a file named
+// dataset1.h You should not change anything except the
+// HOST_DEBUG and PREALLOCATE macros for your timing run.
