Hi Lux, Yes, you can use MPI datatype with shared window. Can you provide more information about the purpose to use shared window thus we can give appropriate suggestion ? Best regards, Min On 2018/05/10 10:05, Luis Cebamanos wrote:

Hi all,

Is there a way to deal with MPI datatypes when using shmm windows? What is the advice to convert a flat MPI code that uses MPI datatypes for halo exchanges to use shmm windows?

Thanks! Lux
