bw_mem_rd - time memory read rate (with overhead)
bw_mem_rd allocates the specified amount of memory, zeros it, and then
times the reading of that memory as a series of integer loads and adds.
Each four byte integer is loaded and added to accumulator.
The size specification may end with ‘‘k’’ or ‘‘m’’ to mean kilobytes (*
1024) or megabytes (* 1024 * 1024).
Output format is "%0.2f %.2f\n", megabytes, megabytes_per_second, i.e.,
This benchmark should move approximately the reported amount of memory.
