Lenient to Errors, Transformations, Irregularities and Turbulence Benchmarks (LetItBench)

LetItBench provides a set of non-optimized and approximation-resilient application which can be targeted by automatic tools to leverage the approximation opportunities that they offer.

Table of Contents

  1. Requirements
  2. Benchmarks
  3. Benchmarks Configuration
  4. Run the Benchmarks

Requirements

  • A recent version of CMake (>=3.12):
    • Most linux distribution provides a CMake package (may be an outdated version).
    • Pre-build binaries for multiple systems can be downloaded from the cmake website.
  • GNU make

Benchmarks

Benchmarks configuration

The benchmarks configuration resides in the LetItBench/benchmarks_configuration folder. This folder contains:

  • MasterConfig.cmake
    • Set the variable COMMON_BATCH_NUM to configure the number of runs.
    • Set the list COMMON_BENCH_COMPILE_OPTION to the relevant compilation options.
    • Set the list COMMON_BENCH_LINK_OPTION to the relevant linker options.
    • Set the list BENCHMARK_SET to point to a new application configuration file to add a new application.
  • <ApplicationName>.cmake
    • Set the list *_COMPILE_OPTIONS to override the common compilation options.
    • Set the list *_LINK_OPTIONS to override the common compilation options.
    • Uncomment *_BATCH_NUM to override the number of batch runs for this application.
    • Create new run by creating a list starting with its name and followed by the application parameters.
    • Disable / Enable runs by removing / adding a run (application parameters) to the *_BENCHMARKS list.

Run the Benchmarks

Follow the following instructions in a terminal:

git clone https://github.com/Syllo/LetItBench.git
mkdir -p LetItBench/build && cd LetItBench/build
cmake ..
make bench       # To run only one time
make batch-bench # To run the benchmarks multiple times in a row (see BATCH_NUM in Configuration)
make gather-data # To gather the data from all the runs into a single file

The results will be available in the directory LetItBench/benchmarks_result_directory.
