Intel® Cilk™ Plus - an extension to the C and C++ languages to support data and task parallelism - is being deprecated in the 2018 release of Intel® Software Development Tools. It will remain in deprecation mode in the Intel® C++ Compiler for an extended period of two years. It is highly recommended that you start migrating to standard parallelization models such as OpenMP* and Intel® Threading Building Blocks (Intel® TBB). For more information see Migrate Your Application to use OpenMP* or Intel® TBB Instead of Intel® Cilk™ Plus.
