For example:
Grid-size= XS (32x32x64)
S (64x64x128)
M (128x128x256)
L (256x256x512)
XL (512x512x1024)

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: 914.458955 time(s): 0.449791 1.733593e-03

Now, start the actual measurement process.
The loop will be excuted in 400 times
This will take about one minute.
Wait for a while
