<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi,<br>
I'm trying to use libfabric on top of PSM and based on the rdm_ping_pong from fabtest I'm not sure of the semantic to interconnect more than 2 processes with the RDM approach (I'm ok with the MSG one for sockets and verbs by using a passive endpoint).<br>
- Need I create an active endpoint for each targeted process (at least for one side)<br>
- In this case how I differentiate the endpoint on the source side as we do not provide target ? (May I just wait connection to them and then check with which node it is connected)<br>
- Can we start more than one "listen" at a time on the source side with the RDM mode ?<br>
<br>
In the same idea I'm asking myself, how to setup connections with more than one process per node, usage of port/service seams inefficient with the rdm_ping_pring test (with PSM, not sockets) ? When I launched two of them (source) on the same host and another
one (remote) on another, I cannot choose which process to join, it always connect to the last started one.<br>
<br>
Thanks in advance,<br>
