Alain, Thank you!
The interface is provided in allocator.hpp, boost version 1.73.0. Sorry there is no in_value and it is in_values. I use the "v" version because I have to divide a vector of "T" objects into parts with different sizes. The "T" is not a primitive type. It is a class defined by myself and the class is complicated.

Hi The in value is a T const&, meaning you're sending one single object. So I wonder why the "v" version is used. Actually, I'm not sure why we are providing that interface. What kind of type is T ? is it a primitive type, a POD or is it more complex ? Cheers ---- Alain Miniussi DSI, Pôles Calcul et Genie Log.

I use the following command in the program, all_gatherv (const communicator& comm, const T& in_value, T* out_values, const std::vector<int>& sizes). The program works well if the size of in_value and out_values is small. However, it fails if the size is big. I just can’t fix it. Any help or advices are greatly appreciated.
