regarding Boost::MPI, does this library serialize custom objects??
this is the object i need to send:
class Lattice{
int numNodes;
int numEdges;
map<int, Edge> edges;
map<int, Node> nodes;
stringstream key;
list< list<int> > keyLists;
bool corrupt;
bool rec;
int nop;
}
//and Edge, Node are classes too:
class Edge{
int n1,n2;
int id;
bool sp;
bool dead;
};
class Node{
bool sp; //special flag
int id, ext;
float x, y, z;
public:
multimap<int,int> eMap;
};
they have their corresponding methods and constructors, but those are their
data structures.
you recommend use Boost::MPI:Serialize or do manual Serialize?
best regards
Cristobal
