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: 0.000345093(=34509.3 usecs)  cpu secs: 0.000346(=34600 usecs)
Minimum time: clock secs: 0.034181(=34181 usecs)  cpu secs: 0.03(=30000 usecs)
Maximum time: clock secs: 0.037475(=37475 usecs)  cpu secs: 0.04(=40000 usecs)

Shared memory:
Average time: clock secs: 0.000349667(=34966.7 usecs)  cpu secs: 0.000349(=34900 usecs)
Minimum time: clock secs: 0.034183(=34183 usecs)  cpu secs: 0.03(=30000 usecs)
Maximum time: clock secs: 0.054774(=54774 usecs)  cpu secs: 0.04(=40000 usecs)
