We are looking for people to help us with the following projects with OpenCilk. If you see anything interesting, please contact us.

Language server

Develop an OpenCilk language server that integrates with OpenCilk's tools. For example, the language server would integrate with Cilksan to allow editors to mark locations in the program's source that are involved in a determinacy race.

Cilksan reporting

Improve the output of Cilksan to syntax-highlight names of functions in the call stack, especially the namespaces and types in C++ function names.


  • Fix GDB to correctly identify stack frames in the cactus stack of a Cilk program.
  • Fix the RR debugger's behavior to handle Cilk's stack switching when rewinding the parallel execution of a Cilk program.
