[libfabric-users] FI_MR_ENDPOINT question

[Biddiscombe, John A.]

For machines that set the FI_MR_ENDPOINT flag - we must bind memory regions to an endpoint.


If I use a separate endpoint for sending and receiving, or worse, threadlocal endpoints (for sending), or a scalable endpoint (for sending)


Must I only use memory regions bound to the exact endpoint I'm actually using for a send  or receive operation (meaning threadlocal pools of registered memory for a threadlocal endpoint setup and separate pools of memory for send/receive).


How strict are the rules? If I bind memory to endpoint 1, and send using endpoint 2 - will it break?


thanks...
