Subject: [dpdk-dev] [PATCH v5 0/4] examples: add performance-thread
Date: Thu, 3 Dec 2015 09:28:21 +0000 [thread overview]
Message-ID: <1449134905-28261-1-git-send-email-ian.betts@intel.com> (raw)
From: Ian Betts <ian.betts@intel.com>
This patchset comprises a layer 3 forwarding derivative intended to
facilitate characterization of performance with different
threading models, specifically:-
1. EAL threads running on different physical cores
2. EAL threads running on the same physical core
3. Lightweight threads running in an EAL thread
Purpose and justification
Since dpdk 2.0 it has been possible to assign multiple EAL threads to
a physical core ( case 2 above ).
Currently no example application has focused on demonstrating the
performance constraints of differing threading models.
Whilst purpose built applications that fully comprehend the DPDK
single threaded programming model will always yield superior
performance, the desire to preserve ROI in legacy code written for
multithreaded operating environments makes lightweight threads
(case 3 above) worthy of consideration.
As well as aiding with legacy code reuse, it is anticipated that
lightweight threads will make it possible to scale a multithreaded
application with fine granularity allowing an application to more
easily take advantage of headroom on EAL cores, or conversely occupy
more cores, as dictated by system load.
To explore performance with lightweight threads a simple cooperative
scheduler subsystem is being included in this example application.
If the expected benefits and use cases prove to be of value, it is
anticipated that this lightweight thread subsystem would become a
library in some future DPDK release.
Changes in this version
* None
Idenitical with the V4 patchset, which comprised 2 patches.
V5 is divided into more 5 patches.
