For those who are building gcc-4.7 from scratch, the cilk/ branch sure looks interesting. It has the Cilk runtime and the cilk extensions to the language built in.
As far as language extensions go, it may seem that Cilk does not add much, but to me the advantage of not manually assigning tasks to threads and work stealing seems like a big win.
Not to be facetious but, one is C the other is C++ and on occaisons it does matter a lot.
OpenMP is good for Fortran style code, where you decorate loops, although I havent looked at the latest OpenMP standards. But on its own C++11 looks very good. I will (and I do) use it where I have uses of C++ template mechanism. But now I am porting some that stuff to D. Generics is so much less verbose and nicer over all.
Though I love the support for type inference in C++11, it does not play well with expression templates, which is my go to reason to turn to C++ in the first place (perhaps the only one prior to C++11).
I know there is a big difference between modern C++11 and C.
C11 has standard threads similarly with what you find in C++11, unfortunately you won't find this implemented by all vendors. I hope to see complete support for C11 threads in GCC and Clang in the near future.
Please stop right there and think at the average Ubuntu user, or at a person that has used Windows as his primary OS and just recently has tried Linux hoping to learn/try/test some C++0x/C++11 codes.
Obviously the linked article was not written with a hard core Linux user in mind.
I understand that, from where you stand, this is trivially simple. Just don't assume everyone has your experience.
it was for... I don't recall exactly, something non-standard gcc did with templates, possibly? Anyways, they sent me the sources pre-patched, I just compiled it.

that I didn't administer, I only used it. I was a real newbie at the time. I just figured that since you specified ubuntu...

I see your point, though. I might be looking back at it with the rose-tinted glasses of experience. Also, when I first skimmed through it I only read up until the point where it said that it was complicated and then I got interrupted by the real world for a while, building suspense.

Looking forward to try it out in a week. Stoked.
