My question is how to send part of class object (in my case matrix object) from one process to another process using MPI_Send and receive using MPI_Recv functions. I tried a lot of way but couldn't do it. I hope you will help me. Thanks in advance. I have write a function to get the pointer address for first parameter of MPI_Send() function.
