Subject: [dpdk-users] Test Pipeline application - lockup
Date: Tue, 29 Dec 2015 02:23:44 -0800 [thread overview]
Message-ID: <CACDuqmkyotw9tUrOsRJOEXXoK_TaWxo9O3fhtTDc-mG=0VKiEw@mail.gmail.com> (raw)
Hi folks,
I am running the test pipeline application using extendible bucket hash
table with 16 byte key size. I have made changes to the test pipeline
application such that for EVERY port instance there are 3 cores: Rx Core,
Worker Core and Tx Core instead of ALL ports mapping to a single Rx/Tx Core
like in the original implementation. This is being done to try and increase
the overall throughput of the application.
In the app_main_loop_worker_pipeline_hash function, I am instantiating a
new pipeline instance for each port and stitching the rings_rx and rings_tx
accordingly. With these changes I am able to get a throughput of ~13Mpps on
one 10G port. But, when I send a high rate traffic (13Mpps each) from BOTH
the ports simultaneously, the traffic stops completely. Stopping the
restarting traffic doesn't seem to be helping. It almost looks like the
pipeline is locked up and not seeing any packets in the Rx rings.
Has anyone encountered this before ? Any idea how to debug/what could be
going wrong ? Appreciate your help !
Regards,
Vijay
