Start rehearsal measurement process.

Measure the performance in 3 times.

MFLOPS: 678.902939 time(s): 0.072769 3.288628e-03

Now, start the actual measurement process.

The loop will be excuted in 2473 times

This will take about one minute.

Wait for a while

Loop executed for 2473 times

topコマンドでモニタしてたけどCPUは50%以上にならない。

コア2個あっても片方のみで処理してる感じ('～')

Kernelの問題かな・・・
