Just go for the most trivial:
MPI_Type_contiguous(sizeof(__float128), MPI_BYTE, &my__float128);
A little bit more info about the optional quad-precision floating-point format
is available on Wikipedia
(https://en.wikipedia.org/wiki/Double-double_%28arithmetic%29#Double-double_arithmetic).

See Section 5.9.5 of MPI-3 or the section named "User-Defined
Reduction Operations" but presumably numbered differently in older
copies of the MPI standard.
An older but still relevant online reference is

Hi all,
I have a question on datatypes in openmpi:
Is there an (easy?) way to use __float128 variables with openmpi?
Specifically, functions like
MPI_Allreduce
seem to give weird results with __float128.
Essentially all I found was
