[Beowulf] MPI Derived datatype + Persistent

[amjad ali]

Hi all,

I read that

MPI Derived datatypes may provide efficient way to send data non-contiguous
in the memory.
MPI Persistent communication may provide efficient way in case some
specified/fix communication is performed in an iterative code.

Can we combine both together to get some enhanced benefit/efficiency?

Better if any body can refer to some tutorial/example-code on this.

Thank you for you attention.

With best regards,
Amjad Ali.
