Try OpenCilk

An integrated open-source platform for task-parallel programming.

OpenCilk makes it easy

  • to write fast parallel code for shared-memory multicores,
  • to analyze and benchmark the parallel scalability of your program, and
  • to detect and debug races or prove that your program execution is race-free.

Use your machine's resources efficiently

OpenCilk provides an ideal environment for developing fast code for applications that run on commodity and cloud multicore computers. It features a simple language, small codebase, and mathematically provable guarantees of good performance.

Cutting-edge technology that's easy for students to learn

OpenCilk is an open-source software development infrastructure for task-parallel programming that allows for substantial code reuse and easy exploration of design choices in language abstraction, compilation strategy, runtime mechanism, and productivity tool development.

Measure parallelism and maximize scalability with automated benchmarking

With CilkScale you can ensure that your program scales up and down to make the most of any host system.

Optimize your code with a compiler that KNOWS parallelism

OpenCilk augments the "middle end" of LLVM to represent parallel control flow and bring every LLVM optimization to bear on your parallelized code.
