Subject: [Boost-users] Performance optimization in Boost using std::vector<>

I have a question related to performance optimization using Boost. I found
trying to figure out which curve (on the graph in the link) represents the
communication of std::vector<int> and std::vector<double>? Is communication
using std::vector<int> and std::vector<double> optimized (is_mpi_datatype)
So I use "boost_mpi" and "boost_serialization" libraries. I include the
header "#include <boost/serialization/vector.hpp>" in my code. Then I send
directly std::vector<int> and std::vector<double> using "world.send(...) "
and world.recv(...)" calls. I fill the vector with some values (for example
I fill ten values) and I get the same ten values on other side of processor
boundary. This thing works but I want to improve communication performance.
I found out in this link
section "User-defined data types" that "Fixed data types can be optimized
for transmission using the is_mpi_datatype type trait. ". Also I studied the
Also this link
shows that std::vector<> are optimized for serialization.
I am now confused that sending std::vector<> like this is good for
performance optimization or not? What other better methods are available? Is
something like this
a good option?
