Further, main code is creating nD array of this class and I want to
create MPI data for exchange of array of such 3D class.

Dear all,
I am confused with the use of MPI derived datatype for classes with
static member. How to create derived datatype for something like
class test{
static const int i=5;
double data[5];
}
Thanks for your help!
Best,
Santosh
