<div class="PlainText">I'm looking into this. The checks in the tcp provider are too strict. I have a patch that fixes that, but I doubt it will help here. I'm still analyzing the rxm code to understand if it's passing the right capabilities to tcp and handling
its checks correctly.<br>

<div class="PlainText">Thanks. Any time you want me to test a patch, I'm ready to go.</div>

<div class="PlainText">In case it helps. If I change the provider to sockets, the code runs, and messages are received now - though the tests fail due to validation of received data (wrong numbers being received) - not sure if this is a bug of mine or not.
The exact same code using tcp;rxm does not receive messages. </div>

<div class="PlainText">I'm using FI_DIRECTED_RECEIVE because some ranks send data to themselves and use the same tag as data coming from other ranks
<br>
</div>
<div class="PlainText">I'm using 64bit tags and I get weird (=I can't explain it well) results if I put some info like rank in the tag using bitmasks - then the sockets version stops working (but I have no idea why making the tags more different/unique would
be an issue (however, mismatched tags would explain the data fail when tests are run with sockets - if the wrong tag is being matched, we get errors, but if I change the tags, nothing matches - should I only use 32bit tags?).</div>

<div class="PlainText">I'm trying to test on gni to see what errors I might get there, but it craps out on me at fi_getinfo, so I must have messed up my libfabric and I'm rebuilding everything again</div>
