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: 0.000353516(=35351.6 usecs)  cpu secs: 0.000353(=35300 usecs)
Minimum time: clock secs: 0.035327(=35327 usecs)  cpu secs: 0.03(=30000 usecs)
Maximum time: clock secs: 0.035404(=35404 usecs)  cpu secs: 0.04(=40000 usecs)

Shared memory:
Average time: clock secs: 0.000355827(=35582.7 usecs)  cpu secs: 0.000356(=35600 usecs)
Minimum time: clock secs: 0.035543(=35543 usecs)  cpu secs: 0.03(=30000 usecs)
Maximum time: clock secs: 0.036427(=36427 usecs)  cpu secs: 0.04(=40000 usecs)
