determines available memory bandwidth by copying large arrays of data in memory.
Quiet; suppress informational messages.
Suppress printing the average of each test.
Select number of loops per test
Select tests to be run. If no -t parameters are given the default is to run all tests. -t0: memcpy() test, -t1: dumb (b[i]=a[i] style) test, -t2: memcpy() with arbitrary block size
Block size in bytes for -t2.

will allocate two
arrays in memory and copy one to the other.
Reported 'bandwidth' is the amount of data copied over the time this operation took.
MiBytes (1024*1024 bytes) of physical memory - you'd better switch off swap or
otherwise make sure no paging occurs. Needless to say that it should not be run
on a busy system.
Multiple thread support.
Better configurability, including using getopt() for parsing arguments.
