<p class="MsoNormal">Hi Jintack,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks for pointing this out. The GASNet code was tested for libfabric 1.2, where the framework and providers weren’t doing some checks. It seems to me that there is a bug in that region of the code for GASNET_SEGMENT_FAST || GASNET_SEGMENT_LARGE.
The newly attached memory does not specify the key – all segments get key 0!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I think we need to revisit that and fix the bug. In the meanwhile, ofi_ep_bind_valid() seems to be correct per the current definition of OFI … there shouldn’t be a need to bind a MR to an EP.<o:p></o:p></p>

<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">I wonder how to bind EP with memory region with flags such as FI_REMOTE_READ or FI_REMOTE_WRITE?<o:p></o:p></p>
<p class="MsoNormal">I’m working on v1.3.0, and ofi_ep_bind_valid() in src/common.c returns error when binding MR with any flags.
<o:p></o:p></p>
<p class="MsoNormal">Should we check flags for FI_CLASS_MR specifically in ofi_ep_bind_valid()?<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Here’s an example of binding EP with MR.<o:p></o:p></p>
