            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: 1802.346986 time(s): 0.228211 1.733593e-03

 Now, start the actual measurement process.
 The loop will be excuted in 788 times
 This will take about one minute.
 Wait for a while
