succinct-perf's Introduction

Succinct Performance Benchmark Tools

This is a performance testing framework for Succinct.

Succinct Version

This framework is applicable for Succinct 1.2+.

Constructing the dataset

Before running any benchmark, the dataset to be benchmarked against needs to be prepared. To do this, simply construct the corresponding Succinct data-structures and persist them to disk as follows:

// Example for constructing SuccinctBuffer and persisting it to disk

// Read all of the file contents into a byte array
Path path = Paths.get("path/to/file");
byte[] data = Files.readAllBytes(path);

// Construct the Succinct data-structures
SuccinctBuffer buffer = new SuccinctBuffer(data);

// Persist the data structures to disk
buffer.writeToFile("path/to/output");

Note that the construction is an expensive operation, and may take several minutes to hours if the dataset is several gigabytes in size.

Running the benchmark

Before running the benchmark, you need to assemble the tool as follows:

mvn clean package

To run the benchmark, use the succinct-perf script provided in the bin/ directory.

It's usage is as follows:

usage: succinct-pref
  -b <arg>   The benchmark to run; the specification format is
			 <class-name>.<method-name>. If only class name is specified,
			 then all benchmarks for that class name will be run. To run
			 all benchmarks for all classes, specify "all"
  -d <arg>   Path to serialized Succinct data. (REQUIRED)
  -e <arg>   Length of extract queries
  -n <arg>   Number of threads for throughput bench (on
			 SuccinctFileBuffer[-TFS])
  -q <arg>   Path to query file that contains query strings (Required for
			 search/count benchmarks).
  -r <arg>   Path where the results will be stored 
  -s <arg>   Storage mode for SuccinctBuffer benchmarks. Can be MEMORY_ONLY
			 or MEMORY_MAPPED.
  -t <arg>   Tachyon master path (REQUIRED if file on TFS)
