The fifth release of the multithreaded language Cilk uses a provably good "work-stealing" scheduling algorithm similar to the first system, but the language has been completely redesigned and the runtime system completely reengineered. The efficiency of the new implementation was aided by a clear strategy that arose from a theoretical ...

WebWork-stealing has become the method of choice for scheduling fork-join parallelism. It is used by MIT Cilk, Intel Cilk Plus, Intel TBB, Microsoft PPL, and OpenMP tasking. The basic notion is that threads create pieces of work. When a thread runs out of work, it becomes a thief that attempts to steal a piece of work from another thread.

Webegy, which is a work stealing strategy of the original Stack-Threads/MP, results in a large steal overhead in the program oftheUnbalancedTreeSearch(UTS)[2],[3]benchmark. In such a case, the steal overhead increases rapidly when the number of processors is more than two. In Cilk, this prob-lem does not occur because Cilk’s workers steal work from WebCilk is very faithful to C - indeed, a properly written Cilk program will turn into a C program with acceptable, serial execution if all Cilk keywords are erased. This is extended to function calls - the spawn keyword can only be applied to Cilk functions, and Cilk functions cannot be called by normal means, instead requiring a spawn.
