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.
