| 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) | |
| 84 | ||
