0/ The OpenCilk project is based on the Tapir/LLVM compiler 
	and the Cheetah runtime library

1/ You have two options to install OpenCilk:
	a/ Download a pre-compiled binary
	b/ Compile from the source

	Both ways would come with a clang/clang++ compiler;
	you would use this specific compiler 
	for your compiling your cilk program.

2/  You can find the binaries or source from the following link
	https://cilk.mit.edu/download/

3/ For Windows users, you can use a virtual machine or
   the embedded Linux system on Window (WSL)

4/ If you DO NOT have an LLVM/Clang compiler on your machine
	you can export the bin directory to your PATH. 
	Then the compiler command would be clang/clang++ for C/C++

5/ If you already have an LLVM/Clang, you may want to
	resolve the conflict with your local compiler: 
	Create an alias or give it a specific name like ``Clang-10''

6/ When compiling your cilk program, remember to include <cilk/cilk.h>
	and use the -fopencilk option for the compiler

7/ the tarball opencilk_examples.tgz has a number of
    examples, including the famous ones: 
    DnC_MM, fibonacci, pmergesort, etc.

     For each of them, there are two subdirectories
     called "cilkplus" and  "opencilk"

     You should use the second one. But, if for some
     reason, you also a cilkplus compiler, you can use
     the first one
