Hi ,
I need to design a data structure to transfer data between nodes by boost.MPI.
Some elements of the the structure has dynamic size.
For example,
typedef struct{
double data1; vector<double> dataVec;
} myDataType;
The size of the dataVec depends on some intermidiate computing results.
If I only declear it as the above myDataType, I think, only a pointer is transfered.
When the data receiver try to access the elements of vector<double> dataVec, it got segmentation fault error.
But, I also need to use the myDataType to declear other data structures.
such as vector<myDataType> newDataVec;
Hi Jack, All you need to do is to define a serialize() function for your data structure, so that it can be serialized by Boost.Serialization. Then you can transfer the datastructure with Boost.MPI Matthias
