Subject: [dpdk-dev] running dpdk application on the same machine with other none dpdk application
Date: Tue, 29 Jan 2019 18:32:20 +0200 [thread overview]
Message-ID: <CACn717hahpyEHZsj+xrSFwLEEvgSWHbQnMsdcrsLZvAYQSNuwg@mail.gmail.com> (raw)
Hi,
We are trying to run a dpdk based application one the same machine with
other java based applications.
In order to do that we isolated the dpdk application cores and disabled
hyperthreading for those cores.
But sporadically we encounter misses over the interface.
We are running on a single socket cpu with 44 hyperthreaded cores.
we are using 5 cores for the dpdk application (which is in fact 10 since
hyperthreading is disabled).
My guess is that probably GC (garbage collection) running from the kernel
and perhaps over the isolated threads causing the misses.
Is there a way to solve this issue? Is there a way to isolate cores for
kernel processes/threads?
Thanks in advance,
Shirley.
