Jie,
A question on implementation multi-rail with uDAPL connections.
What I did is open 2 IAs (corresponding to the 2 ports on
HCAs) on each
node.
Then create one EP for each IA, and connect those EPs to the
corresponding
EP at other node.
Then data been transferred via both EP-connections.
Did you verify data flow is across independent HCA channels
using perfquery?
Don't know about perfquery, will use this to verify today.
However, I used a rather simple way to verify the both rail
has been used for data transferring.
The both rail writes to different remote buffer, and the written data
has been confirmed at the remote side.
I have been notice that there's a MULTIPATH connection flag for dapl,
but I did
not use it. What's the use of it?
Multipath is not supported at this time.
I will roll up a uDAPL test and see if I can verify performance.
Thanks for this.
