    When I test "matmul" in the polly directory, I get the following performance data:<br>
//============================<u></u>===<br>
--> 12. Compare the runtime of the executables<br>
time ./matmul.normalopt.exe<br>
0:23.53 real, 23.48 user, 0.00 sys<br>
time ./matmul.polly.interchanged.<u></u>exe<br>
0:22.86 real, 22.82 user, 0.01 sys<br>
time ./matmul.polly.interchanged+<u></u>tiled.exe<br>
0:22.87 real, 22.83 user, 0.00 sys<br>
time ./matmul.polly.interchanged+<u></u>tiled+vector.exe<br>
0:22.53 real, 22.48 user, 0.02 sys<br>
time ./matmul.polly.interchanged+<u></u>tiled+vector+openmp.exe<br>
0:05.88 real, 46.71 user, 0.02 sys<br>
//============================<u></u>===<br>
    The data is different from the official site "<a href="http://polly.llvm.org/example_manual_matmul.html" target="_blank">http://polly.llvm.org/<u></u>example_manual_matmul.html</a>" results. Any advices? Thanks.<br>
