Grid-size =
mimax = 128 mjmax = 128 mkmax = 256
imax = 127 jmax = 127 kmax =255
Start rehearsal measurement process.
Measure the performance in 3 times.
MFLOPS: 2107.073046 time(s): 0.195207 1.733593e-03
Now, start the actual measurement process.
The loop will be excuted in 922 times
This will take about one minute.
Wait for a while
