I need to design a data structure to transfer data between nodes on Open MPI system.
Some elements of the the structure has dynamic size.
double data1;vector<double> dataVec;
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;
I cannot declear myDataType in a function , sucjh as main(), I got errors:
main.cpp:200: error: main(int, char**)::myDataType; uses local type main(int, char**)::myDataType;
Any help is really appreciated.
