Hi,
As far as I know, it is not possible to send objects in MPI,
maybe OOMPI (http://www.osl.iu.edu/research/oompi/) can help,
someone knows if this is an alive developing project?
On the other hand, you can send the size and the vector<int>
separately:
> //global code
>
> vector<int> data; //unknown size
>
> if (taskID == Sender){
> data.push_back(1);
> data.push_back(2);
int size = data.size();
MPI_Send(&size,1,MPI_INT ....);
MPI_Send(&data[0],size,MPI_INT .... ); // send
>
> MPI_Send(&data[0],data.size(),MPI_INT .... ); // send
> }
> if (taskId == Receiver){
Here, first you must receive size and then data.
> // QUESTION here -> how to receive the sending data ? the receiver
> has no knowledge of the data size
> }
