Hi,While working with multiple file source codes, what is the scope of theMPI derived data types. - I am trying to declare a derived data type for a complex struct containing dynamic arrays in main() function in a C code.- In a different function located in a seperate file, I am trying to usethe data type for sending a struct using MPI_Send. The corresponding receive is again in a separate function which may or may not exist in the same file. However, it throws as error as it doesn't knows the declared data typeoutside main( ). How should the data type be declared to have it's scopeanywhere in the code ?
It should be declared as a global. However, this is not a data-type specific thing, it's a classical symbol visibility problem in C.
Is any derived data type declared valid anywhere in MPI_COMM_WORLD ?
Absolutely not and it will not be on the foreseeable future. I think you kind of mix the concept of variable visibility with the concept of comm_world in MPI. They do not have anything in common.
