Vector Usage in MPI(C++)
- by lsk1985
I am new to MPI programming,stiil learning , i was successful till creating the Derived data-types by defining the structures . Now i want to include Vector in my structure and want to send the data across the Process. for ex:
struct Structure{
//Constructor
Structure(): X(nodes),mass(nodes),ac(nodes) {
//code to calculate the mass and accelerations
}
//Destructor
Structure() {}
//Variables
double radius;
double volume;
vector<double> mass;
vector<double> area;
//and some other variables
//Methods to calculate some physical properties
Now using MPI i want to sent the data in the structure across the processes. Is it possible for me to create the MPI_type_struct vectors included and send the data?
I tried reading through forums, but i am not able to get the clear picture from the responses given there. Hope i would be able to get a clear idea or approach to send the data
PS: i can send the data individually , but its an overhead of sending the data using may MPI_Send/Recieve if we consider the domain very large(say 10000*10000)
