  31 Building the tarball
  32 --------------------
  33 As long as cc is in your path, (gcc on Linux),
  34
  35 % tar xf libMicro.tar
  36 % make
  37
  38 will build the benchmark suite.
  39
  40 Running the benchmarks
  41 -----------------------
  42
  43 A set of generic scripts to invoke each micro benchmark
  44 are created in the bin directory; these may be invoked
  45 directly.  Note that the actual binaries are created in
  46 OS-specific directories; this allows one to build for
  47 all varients (x86/sparc/Solaris/Linux) in one place.
  48
  49 To collect a complete set of benchmarks, use the bench
  50 script and redirect its output to a file.
  51
  52 % ./bench > output
  53
  54 To compare the output of two or more runs, use multiview in the src
  55 directory:
  56
  57 % ./multiview reference compare1 compare2 compare2 > compare.html
  58 %
  59
  60 where the reference and compare files contain the output of different
  61 libmicro runs.
  62
  63 The compare.html file will allow quick comparisons to be drawn,
  64 allowing a variety of experiments to be quickly analyzed.
  65
  66 All benchmarks support the following options:
  67
  68        [-1] (single process; overrides -P > 1)
  69        [-A] (align with clock)
  70        [-B batch-size (default 10)]
  71        [-C minimum number of samples (default 0)]
  72        [-D duration in msecs (default 10s)]
  73        [-E (echo name to stderr)]
  74        [-H] (suppress headers)
  75        [-I] specify approx. time per op in nsecs
  76        [-L] (print argument line)
  77        [-M] (reports mean rather than median)
  78        [-N test-name ]
  79        [-P processes (default 1)]
  80        [-S] (print detailed stats)
  81        [-T threads (default 1)]
  82        [-V] (print the libMicro version and exit)
  83        [-W] (flag possible benchmark problems)
