CppSs -- a C++ Library for Efficient Task Parallelism

TL;DR

CppSs is a C++11-compatible library enabling efficient task parallelism without special compilers, using runtime analysis of data dependencies defined by directionality clauses, purely in native C++.

Contribution

It introduces a C++ library that simplifies task parallelism by analyzing data dependencies at runtime without requiring specialized compilers.

Findings

Supports any C++11 compiler

Provides flexible data dependency clauses

Achieves efficient task parallelism in native C++

Abstract

We present the C++ library CppSs (C++ super-scalar), which provides efficient task-parallelism without the need for special compilers or other software. Any C++ compiler that supports C++11 is sufficient. CppSs features different directionality clauses for defining data dependencies. While the variable argument lists of the taskified functions are evaluated at compile time, the resulting task dependencies are fixed by the runtime value of the arguments and are thus analysed at runtime. With CppSs, we provide task-parallelism using merely native C++.
