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.
