Description (last modified by Sebastian Huber)

Cilk Plus is a C++ language extension developed by Intel. It is proposed as a C++ standard extension. It uses a work stealing scheduler. Similar to OpenMP it consists of two parts,

  • the code generation by the compiler, and
  • a run-time library.

The code generation works for the RTEMS using a recent GCC. It is feasible to port the run-time library (libcilkrt) to RTEMS. However, some issues must be dealt with.

  • Currently virtual memory via mmap() is used to manage the worker stacks (cactus-stack).
  • This could be changed to use a pool allocator.
  • What happens in case of stack overflows, e.g. no protection pages?
