NAME

       bw_mem_rd - time memory read rate (with overhead)

SYNOPSIS

       bw_mem_rd size

DESCRIPTION

       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

       Output format is "%0.2f %.2f\n", megabytes, megabytes_per_second, i.e.,

       8.00 25.33

MEMORY UTILIZATION

       This benchmark should move approximately the reported amount of memory.
