Hi Vineet,

what is the template parameter of your vector? If it is just a double or 
float or another pod type you can safely do

MPI_Send(&vec[0], ...)

On the receive side you would have to probe the incoming message using 
MPI_Probe - Retrieve the message length from the status variable and 
then call

vec.resize(...)
MPI_Recv(&vec[0], ...)

Note that boost::MPI 
(http://www.boost.org/doc/libs/1_39_0/doc/html/mpi.html) allows you to 
send a vector without such "tricks".

Hope this helps.
Dorian
