This program measures the throughput of normal and shared memory.
All measurements are done 100 times with memory regions
of the size 1048576 bytes.

Normal Memory:
Average time: clock secs: 1.8742e-05(=18742 usecs)  cpu secs: 1.236e-05(=12360 usecs)
Minimum time: clock secs: 0.009649(=9649 usecs)  cpu secs: 0(=0 usecs)
Maximum time: clock secs: 0.355191(=355191 usecs)  cpu secs: 0.07(=70000 usecs)

Shared memory:
Average time: clock secs: 1.74123e-05(=17412.3 usecs)  cpu secs: 1.208e-05(=12080 usecs)
Minimum time: clock secs: 0.009663(=9663 usecs)  cpu secs: 0(=0 usecs)
Maximum time: clock secs: 0.322323(=322323 usecs)  cpu secs: 0.08(=80000 usecs)
