1. Cilk++ has nested parallelism that works and provides guaranteed speed-up. OpenMP has nested parallelism, but it is a memory hog and not reliable.

2. Cilk++ guarantees space bounds. On P processors, Cilk++ uses no more than P times the stack space of a serial execution. In OpenMP, not so.

3. Cilk++ has a race detector for debugging and software release. With OpenMP, you are on your own.

4. Cilk++ has serial semantics. With OpenMP, you do not have this benefit – only a subset of OpenMP supports serial semantics.

5. Cilk++ has a solution for global variables (a construct called "hyperobjects"). OpenMP does not.

do you distribute your work under GPL? If so, then you wouldn't see a change under CAPL.

GPL 2 or 3? The Cilk++ page says if it is "used by others" and not open source you need to pony up. This is perfectly acceptable by GPL2.

sorry, I'm not clear- do you mean you distribute it under GPL2, or that GPL2 allows use without releasing the resulting work?

TBB borrows the scheduling portion, but requires substantial code restructuring, and doesn't have a solution for the global variable problem analogous to Cilk's hyperobjects.

interesting point - worth a comment in the blog post

Cilk++ is a considerable upgrade to MIT Cilk: support for C++ (rather than just C), for Visual Studio (rather than just GCC), support for loops (rather than just recursion). It's considerably more transparent to the developer.

so let's say the team actually wants to target developers rather than suits - what are the key things you'd change about the web site?

thanks in advance.

It's easy: show me the code. Links to quick examples and tutorials that show me what and how this language can do are amazingly useful. Pretty much you want the primary focus to be on using your language, not selling it. You have a navbar across the top; at first glance I know for 100% certainty only what two of those links will do for me ("home" and "company").

In short, look at http://python.org/ , http://www.perl.org/ , and http://www.ruby-lang.org/en/ . Focus on enabling the developer to do something useful as soon as possible. Focus on community, libraries, etc... If you make one change and only one change to the site, add a link titled "Getting started"... make it a wiki. See http://www.erlang.org/starting.html for more inspiration. Right now it feels like the marketing department designed the the cilk site.

thank you.

Does the following help? (A link to the alpha documentation.) http://www.cilk.com/resources-for-multicoders/documentation-...

We will post a bunch of code examples as well, but wanted to get something up sooner than later.
