Hi @garywangcn, can you please try to add the -x 0 (gid index) parameter?
from perftest.

@galpress thanks for you information, it works.
May I know why the gid index must be configured? And is there any instruction about how to run perf tools on aws EFA?

EFA only works with GIDs addressing, so the -x parameter is mandatory.
By perf tools you mean perftest? I don't think we have special EFA instructions for that.
You can find more information in:
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/efa.html

Thanks a lot for your help. @galpress
I will close this ticket.
Correct command for efa are:
client: sudo ./ib_send_lat -d efa_0 -s a xx.xx.xx.xx -c SRD -x 0
server: sudo ./ib_send_lat -d efa_0 -s a -c SRD -x 0
