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.
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.
