Hi I am parallelizing an existing serial project, and by far I just want to parallelize a few fucntions into cilk approach. There are lots of source files and I don't want to change all their extensions to .cilk. Is it possible that some upper level c++ codes call a cilk function ? If yes, how ? I found a chapter explaining how to mix c++ and cilk code in your document but only few paragraphs talk about serial code to call cilk code. I still don't quite understand how to do it after reading the document. Thank you very much
