TechXplore: Researchers mine cache of Intel processors to speed up data packet processing

By Media Coverage

Developed with Ericsson Research, the slice-aware memory-management scheme allows frequently used data to be accessed more quickly via the last-level cache of memory (LLC) of an Intel Xeon CPU. By establishing a key-value store and allocating memory in a way that it maps to the most appropriate LLC slice, they demonstrated both high-speed packet processing and improved performance of a key-value store.

DPDK Community Lab Publishes Relative Performance Testing Results

By Blog

By Jeremy Plsek, Lincoln LaVoie and Patrick MacArthur

The DPDK Community Lab is an open, independent testing resource for the DPDK project. Its purpose is to perform automated testing on incoming patch submissions, to ensure the performance and quality of DPDK is maintained. Participation in the lab is open to all DPDK project participants.

For some time now, the DPDK Community Lab has been gathering performance deltas using the single-core packet I/O layer 2 throughput test from DTS for each patch series submitted to DPDK compared to the master branch. We are pleased to announce that the  Lab has recently been allowed to make these results public. These results are also now published to Patchwork as they are automatically generated. These results currently contain Mellanox and Intel devices, and the lab is able to support hardware from any DPDK participants wishing to support these testing efforts.

To view these results, you can go to DPDK Community Lab Dashboard via the following link: The dashboard lists an overview of all active patch series and their results. Detailed results can be viewed by clicking on the patch series. If a patch fails to merge into master, a build log will show to help identify any issues. If a patch cleanly merges into master, performance delta results will show for each participating member.

The Lab is hosted by the University of New Hampshire InterOperability Laboratory, as a neutral, third party location. This provides a secure environment for hosting equipment and generating unbiased results for all participating vendors. Lab participants, i.e. companies hosting equipment in the testing, can securely access their equipment through a VPN, allowing for maintenance and performance tuning, as the DPDK project progresses.

The Lab works by polling the Patchwork API. When new patches are submitted, the CI server merges them with the master branch and generates a tarball. Each participating system unpacks and installs the DPDK tarball and then runs the performance testing against this DPDK build. When all systems have finished testing, the CI gathers the results into our internal database to be shown on the Dashboard, and sends final reports to Patchwork to show up on the submitted patch. This allows patch submitters to utilize Patchwork to view their individual results, while also allowing anyone to quickly see an overview of results on the Dashboard. The system provides maintainers with positive confirmation of the stability and performance of the overall project.

In the future, we plan to open the Lab to more testing scenarios, such as performance testing of other features, beyond single-core packet I/O layer 2 throughput, and possibly running Unit Tests for DPDK. Additional features will be added to the Dashboard, such as showing graphs of the performance changes of master over time.

DPDK’s 18.05 Release, Named ‘Venky’ in Honor of “the Father of DPDK,” Brings Even Broader High-performance Accelerated Network Support to Cloud and Telco Markets

SAN FRANCISCO – June 21, 2018 – Following the move one year ago to the Linux Foundation, the Data Plane Development Kit (DPDK) project today announced the availability of its milestone DPDK 18.05 ‘Venky’ software release, named after Venky Venkatesan, who was known as “the father of DPDK”. The DPDK project’s 5th major release since joining the Linux Foundation accelerates packet processing workloads running on a wide variety of CPU architectures (including x86, ARM and Power) and supports many enhancements for Encryption, Compression and Packet processing.

Network performance, throughput, and latency are increasingly important for a whole range of applications and implementations such as 5G, Cloud, Network Functions Virtualization (NFV),  wireless core and access, wireline infrastructure, routers, load balancers, firewalls, video streaming, VoIP, SD-WAN, vCPE and more as the ways in which the world communicates rely more and more on fast and stable networks. By enabling very fast packet processing, DPDK makes it possible for organizations to move performance-sensitive applications – like the backbone for mobile networks and voice –  to the Cloud and help create higher performing edge devices.

“The first release of DPDK open source code came out eight years ago; since that time, we’ve built a vibrant community around the DPDK project,” said Jim St. Leger, DPDK Board chair and Data Plane Software Product Marketing Manager, Intel. “We’ve created a series of global DPDK Summit events where the community developers and code consumers gather. The growth in the number of code contributions, participating companies, and developers working on the project continues to reflect the robust, healthy community that the DPDK project is today.”

A true community effort, DPDK 18.05 ‘Venky’ release was built with contributions from over 160 developers, and over 1700 commits across more than 25 organizations.

Key highlights include support for:

  • Compression and Cryptography
  • Dynamic Memory Scaling – faster application launches
  • Event Mode – Hardware or software Event driven scheduler
  • Better Virtual Function Management
  • Updated driver support for Smart NICs, FPGA and System on Chip (SoCs)
  • Future Hardware acceleration of data path, encryption and compression
