hi,

I understand that atomic<T> is already a part of C++0x standard, but no implementation in boost?

There is the standard interface C++ Atomic Types and Operations
 http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2427.html

I don't know of any portable and complete implementation. Oliver has implemented it partially in his ThreadPool library. I think Anthony has also an implementation on Interl processors.

It will be great if you and all the interested people woked together towards a complete implementation of the standard interface.
