NAME

       milli, micro, nano, mb, kb - the lmbench reporting subsystem

SYNOPSIS

       #include ‘‘lmbench.h’’

       void milli(char *s, uint64 n)

       void micro(char *s, uint64 n)

       void nano(char *s, uint64 n)

       void mb(uint64 bytes)

       void kb(uint64 bytes)

DESCRIPTION

       Creating benchmarks using the lmbench timing harness is easy.  Since it
       is so easy to measure performance using  lmbench,  it  is  possible  to
       quickly  answer questions that arise during system design, development,
       or tuning.  For example, image processing

       There are two attributes that are critical for performance, latency and
       bandwidth,  and  lmbench’s  timing harness makes it easy to measure and
       report results for both.  The measurement  interface,  benchmp  is  the
       same,  but  the  reporting functions are different.  Latency is usually
       important for frequently executed operations, and bandwidth is  usually
       important when moving large chunks of data.

       void milli(char *s, uint64 n)
              print  out  the  time  per operation in milli-seconds.  n is the
              number of operations during the timing interval, which is passed
              as  a  parameter  because  each  loop_body  can  contain several
              operations.

       void micro(char *s, uint64 n)
              print the time per opertaion in micro-seconds.

       void nano(char *s, uint64 n)
              print the time per operation in nano-seconds.

       void mb(uint64 bytes)
              print the bandwidth in megabytes per second.

       void kb(uint64 bytes)
              print the bandwidth in kilobytes per second.

FUTURES

       Development of lmbench is continuing.
