Hi when I use sockperf under ARM machine, It tell me sockperf: ERROR: _seqN > m_maxSequenceNo (errno=0 Success)。 I change v3.6 to v3.7 but that not slove my problem。

Hello @GeekerHua , do you see such issue just for under-load scenario? Did you try ping-pong and throughput?

GeekerHua commented

throughput
ping-pong not work, throughput work well

could you provide output for pp case too.

could you provide output for pp case too.

pp output nothing. It's on the picture.

igor-ivanov commented

there is no output for pp case on your screen because it is comment out ##.

@GeekerHua do you have any update?

Hi,

It also happens to me on Arm with pp test when using --mps parameter.

Setup

  • Amazon Linux 2 (based on RHEL) on AWS with kernel (4.14.248-189.473.amzn2.aarch64).
  • Arm64 (64 CPUs)
  • sockperf, version 3.7-11.gita57ffb579002

It works fine with:
./sockperf server --ip x.y.z.w --tcp --port 5001 --msg-size 400
./sockperf ping-pong --ip x.y.z.w --tcp --port 5001 --time 30 --msg-size 400 --range 100 --full-rtt

It get to error with appending --mps 1000 to the client

[ec2-user@ip-172-31-16-82 sockperf]$ ./sockperf ping-pong --ip x.y.z.w --tcp --port 5001 --time 30 --msg-size 400 --range 100 --full-rtt --mps 1000
sockperf: == version #3.7-11.gita57ffb579002 ==
sockperf[CLIENT] send on:sockperf: using recvfrom() to block on socket(s)

[ 0] IP = X.Y.Z.W PORT = 5001 # TCP
sockperf: Warmup stage (sending a few dummy messages)...
sockperf: Starting test...
sockperf: ERROR: _seqN > m_maxSequenceNo (errno=0 Success)

From very fast look, maybe the calc of _maxSequenceNo at bringup() function is related.

We will look at possible reason.
