Hi,

When you can fi_write, you need to specify which end point you are targeting to (alongside with memory address).

So only the target endpoint will generate completion.

    Hi,

    There is an interaction I don't quite understand. If a provider does
    *not* have FI_MR_ENDPOINT the memory regions are bound to domains. But
    when the are target with a RMA write that provides cq data with
    FI_REMOTE_CQ_DATA where should the completion be generated ? because
    there may be one, zero, or many endpoints associated with this domain.

    Or is this flag only applicable with FI_MR_ENDPOINT ?
