The benchmarks are currently bundled as a single download. Each subdirectory contains one test or a small set of related tests. Some of the tests depend on code or libraries in other subdirectores. The shell scripts, ant scripts, and makefiles expect a common parent directory.
Furthermore, all of these tests utilize the timing libraries that are part of the PoorMansTimingAndProfiling libraries. You will need to download the timing and profiling code into the same directory that you put the benchmarks into.
Each subdirectory in this package contains a separate "readme" file providing more information on the test(s) and the contents of the subdirectory.
You can download the sources from here.
