NAMEbw_mem_rd - time memory read rate (with overhead)
DESCRIPTIONbw_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).
OUTPUTOutput format is "%0.2f %.2f\n", megabytes, megabytes_per_second, i.e., 8.00 25.33
MEMORY UTILIZATIONThis benchmark should move approximately the reported amount of memory.
