Benchmark for the Formally Verified Java Implementation of In-Place Super Scalar Sample Sort

The src directory contains the benchmark code. The algorithm implementation is included as a submodule in external/ips4o-verify.

Usage

The code can be compiled using ant, provided you have JDK 20 installed. To run the benchmarks, use the following commands:

ant
java -cp bin edu.kit.algo2.ips4o.benchmark.Main

This will run all the benchmarks for input sizes 2 through 2²⁷. If you are only interested in a subset, you can append the following options:

--base <n> sets the base for the input size to <n>. Default is 2.
--exponents <min> <max> sets the minimum and maximum exponents for the input size. Defaults are 1 and 27, respectively.
- For example, to run the benchmarks with input sizes 100, 1000, 10000, use --base 10 --exponents 2 4.
--iterations <n> sets the number of times each benchmark is repeated. Default is 5.
--distribution sets the input distribution for which benchmarks should be run. Default is all.
- Valid options are: UNIFORM, ONES, SORTED, REVERSE, ALMOST_SORTED, UNSORTED_TAIL, EXPONENTIAL, ROOT_DUPS, ROOT_CENTER_DUPS, P78CENTER_DUPS.
--algo <name> sets the algorithm to be benchmarked. Default is ips4o.
- Valid options are: ips4o, std.
