Thanks Matus,

Do you have any sample how to copy list of files using boost.asio?
It is not just to stream binary data of file I need to send some meta data (filenames, ...) for multiple files.
Is there any standard way doing that?

Thanks
Ervin

If You just want to copy files then using MPI is IMHO an overkill.
Boost.Asio is probably a better choice.
