Wops, I forgot to mention the url, http://www.cs.virginia.edu/stream
and the files (stream_d.c and second_wall.c) are available from
ftp://ftp.cs.virginia.edu/pub/stream/Code .

Compile it as gcc -O stream_d.c second_wall.c -o stream, and just run
the test (You need to have atleast 32M free during the test). It takes
about 10 secs to run. Do not use more optimizing that -O, because then
gcc 'cheats' and gets rid of some of the loops.

Happy benchmarking,

/Mikael
