Cilk work stealing

The Cilk scheduler uses a policy called "work-stealing" to divide procedure execution efficiently among multiple processors. Again, it is easiest to understand if we look first at how Cilk code is executed on a single-processor machine. The processor maintains a stack on which it places each frame that it … See more Cilk, Cilk++, Cilk Plus and OpenCilk are general-purpose programming languages designed for multithreaded parallel computing. They are based on the C and C++ programming languages, which they extend with … See more The principle behind the design of the Cilk language is that the programmer should be responsible for exposing the parallelism, identifying elements that can safely be executed in parallel; it should then be left to the run-time environment, particularly the See more • Official website for OpenCilk • Intel's Cilk Plus website • Cilk Project website at MIT • Arch D.

Work stealing - Wikipedia

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. WebWork-stealing The Cilk scheduler uses a policy called "work-stealing" to divide procedure execution efficiently among multiple processors. Again, it is easiest to … WebIn this paper, we explore using randomized work stealing to support large-scale soft real-time applications that have timing constraints but do not require hard guarantees. De-spite the unpredictable nature of work stealing, our exper-iments with benchmark programs found that work stealing (in Cilk Plus) delivers smaller maximum response times than port pair shipping
