When running this benchmark on a 2.66GHz Dual-Core Intel Xeon, I obtain this table (MFLOPS
is million floating-point operations per second):
n max MFLOPS compiler flags
100 329.813 gcc
Problem 1 (6 points) Study the compile options of the gcc compiler, and in particular the
optimization flags, and the flags that are related to SSE instructions.
Produce the same table for each of penguin, mills, and your own computer. Keep the same
flags as above, but you can also add other flags. Try to obtain as high count as you can. Submit
the three tables and a discussion on your results.
Note. You can obtain information about your system
