Issue with MPI_ALLREDUCE with MPI_REAL16

713 Views

Hello!

I am running a quad precision code in MPI. However, when I perform MPI_ALLREDUCE with MPI_REAL16 as datatype, the code gives a segmentation fault. How do I incorporate quad precision reduction operations in MPI. Any advice would be greatly appreciated.

Regards
