Usage: mbw [options] array_size_in_MiB
Options:
-n: number of runs per test (0 to run forever)
-a: Don't display average
-t0: memcpy test
-t1: dumb (b[i]=a[i] style) test
-t2: memcpy test with fixed block size
-b <size>: block size in bytes for -t2 (default: 262144)
-q: quiet (print statistics only)
(will then use two arrays, watch out for swapping)
'Bandwidth' is amount of data copied over the time this operation took.
The default is to run all tests available.
