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.
