[dpdk-users] Running Distributed Software Eventdev

[dpdk-users] Running Distributed Software Eventdev

[Liron Himi]

Hi,

I'm trying to check what can I gain from the DSW-Eventdev compared to SW-eventdev.
I could run the sw-eventdev with the following command
./dpdk-test-eventdev -c 0xf -s 0x2 --vdev=event_sw0 -- --test=perf_queue --plcores=2 --wlcore=3 --stlist=p --nb_pkts=0 --verbose 2

Now, I'm trying to the run the DSW but with no luck. I always get
"0.000 mpps avg 0.000 mppserror: perf_launch_lcores() No schedules for seconds, deadlock"

I have the tried the following commands:
./dpdk-test-eventdev -c 0xf -s 0x2 --vdev=event_dsw -- --test=perf_queue --plcores=2 --wlcore=3 --stlist=P --nb_pkts=0 --verbose 2

./dpdk-test-eventdev -c 0xf --vdev=event_dsw -- --test=perf_queue --plcores=2 --wlcore=3 --stlist=P --nb_pkts=0 --verbose 2



Please advise how can I get it running

Regards,
Liron

From what I recall, dpdk-test-eventdev is asking for some specific capabilities from the eventdev it's testing - some of which DSW doesn't implement.

A while back I posted a benchmark program on the dev mailing list:
https://mails.dpdk.org/archives/dev/2018-November/119947.html

It can be run with both DSW and SW, if you want to do a comparison. Of course, if you want to see the real effect of moving between different event schedulers, you need a real application and a realistic workload.

(Sorry about the top posting.)

Hi Mattias,

Thanks for the info.

Do you have some command examples for how to run your benchmark program.

Regards,
Liron
