SpecLib

This thread-level speculation (TLS) library provides a framework to parallelize loops in shared memory systems with automatic speculative parallelization techniques based on C++ threads.

Requirements and how to use

This is a header-only library and only uses elements from the standard library, thus it has no extra dependencies. You only need to import the files from the include directory in your project. All files from include folder are needed, but you only must include in your code the main file speclib\speclib.h (e.g. #include "speclib/speclib.h").

The minimum version of C++ required by the library is C++14 (e.g. -std=c++14).

The provided tests and benchmarks can be compiled and executed using cmake and/or ccmake.

Examples and documentation

  • The doc directory contains the supporting documentation for the use and understanding of the library.

  • The include subfolder contains all the files needed to use the library.

  • The tests/basic_tests directory contains some basic test examples that allow you to quickly test the correct operation of the library.

  • The tests/benchmarks directory contains some benchmark examples that can be used to evaluate the library performance. It also contains their sequential versions.

  • The SpecLib library and its model are described and compared with other alternatives in the publication A new thread-level speculative automatic parallelization model and library based on duplicate code execution (DOI 10.21203/rs.3.rs-3405920/v1).
