[lustre-discuss] LNet Multi-Rail config - with BODY!

[Gwen Dawes]

Hi folks,

Let's try that again.

I'm in the luxury position of having four IB cards I'm trying to
squeeze the most performance out of for Lustre I can.

I have a small test setup - two machines - a client (2.12.9) and a
server (2.15.3) with four IB cards each. I'm able to set them up as
Multi-Rail and each one can discover the other as such. However, I
can't seem to get lnet_selftest to give me more speed than a single
interface, as reported by ib_send_bw.

Am I missing some config here? Is LNet just not capable of doing more
than one connection per NID?
