Lace is a work-stealing framework for multi-core fork-join parallelism. The framework is written in C and implements work-stealing in a style similar to frameworks like Cilk and Wool.
The novelty of Lace is that it uses a novel scalable double-ended queue for its implementation of work-stealing and that it offers a feature where workers cooperatively interrupt their current tasks to execute a new task frame.
Lace is developed (© 2011-2016) by the Formal Methods and Tools group at the University of Twente as part of the MaDriD project, which was funded by NWO, and (© 2016-2017) by the Formal Methods and Verification group at the Johannes Kepler University Linz as part of the RiSE project.

Lace requires CMake for compiling and hwloc (libhwloc-dev) to pin workers and allocate memory on the correct CPUs/memory domains.
It is recommended to build Lace in a separate build directory:
mkdir build
cd build
cmake ..
make && make test && make installIt is recommended to use ccmake to configure the build settings of Lace.
