Introducing VMmark ML

VMmark has been the go-to virtualization benchmark for over 12 years. It’s been used by partners, customers, and internally in a wide variety of technical applications. VMmark1, released in 2007, was the de-facto virtualization consolidation benchmark in a time when the overhead and feasibility of virtualization was still largely in question. In 2010, as server consolidation became less of an “if” and more of a “when,” VMmark2 introduced more of the rich vSphere feature set by incorporating infrastructure workloads (VMotion, Storage VMotion, and Clone & Deploy) alongside complex application workloads like DVD Store. Fast forward to 2017, and we released VMmark3, which builds on the previous versions by integrating an easy automation deployment service alongside complex multi-tier modern application workloads like Weathervane. To date, across all generations, we’ve had nearly 300 VMmark result publications (297 at the time of this writing) and countless internal performance studies.

Unsurprisingly, tech industry environments have continued to evolve, and so must the benchmarks we use to measure them. It’s in this vein that the VMware VMmark performance team has begun experimenting with other use cases that don’t quite fit the “traditional” VMmark benchmark. One example of a non-traditional use is Machine Learning and its execution within Kubernetes clusters. At the time of this writing, nearly 9% of the VMworld 2019 US sessions are about ML and Kubernetes. As such, we thought this might be a good time to provide an early teaser to VMmark ML and even point you at a couple of other performance-centric Machine Learning opportunities at VMworld 2019 US.

Although it’s very early in the VMmark ML development cycle, we understand that there’s a need for push-button-easy, vSphere-based Machine Learning performance analysis. As an added bonus, our prototype runs within Kubernetes, which we believe to be well-suited for this type of performance analysis.

Our internal-only VMmark ML prototype is currently streamlined to efficiently perform a limited number of operations very well as we work with partners, customers, and internal teams on how VMmark ML should be exercised. It is able to:

  1. Rapidly deploy Kubernetes within a vSphere environment.
  2. Deploy a variety of containerized ML workloads within our newly created VMmark ML Kubernetes cluster.
  3. Execute these ML workloads either in isolation or concurrently to determine the performance impact of architectural, hardware, and software design decisions.

VMmark ML development is still very fluid right now, but we decided to test some of these concepts/assumptions in a “real-world” situation. I’m fortunate to work alongside long-time DVD Store author and Big Data guru Dave Jaffe on VMmark ML.  As he and Sr. Technical Marketing Architect Justin Murray were preparing for their VMworld US talk, “High-Performance Virtualized Spark Clusters on Kubernetes for Deep Learning [BCA1563BU]“, we thought this would be a good opportunity to experiment with VMmark ML. Dave was able to use the VMmark ML prototype to deploy a 4-node Kubernetes cluster onto a single vSphere host with a 2nd-Generation Intel® Xeon® Scalable processor (“Cascade Lake”) CPU. VMmark ML then pulled a previously stored Docker container with several MLperf workloads contained within it. Finally, as a concurrent execution exercise, these workloads were run simultaneously, pushing the CPU utilization of the server above 80%. Additionally, Dave is speaking about vSphere Deep Learning performance in his talk “Optimize Virtualized Deep Learning Performance with New Intel Architectures [MLA1594BU],“ where he and Intel Principal Engineer Padma Apparao explore the benefits of Vector Neural Network Instructions (VNNI). I definitely recommend either of these talks if you want a deep dive into the details of VNNI or Spark analysis.

Another great opportunity to learn about VMware Performance team efforts within the Machine Learning space is to attend the Hands-on-Lab Expert Lead Workshop, “Launch Your Machine Learning Workloads in Minutes on VMware vSphere [ELW-2048-01-EMT_U],” or take the accompanying lab. This is being led by another VMmark ML team member Uday Kurkure along with Staff Global Solutions Consultant Kenyon Hensler. (Sign up for the Expert Lead using the VMworld 2019 mobile application or on my.vmworld.com.)

Our goal after VMworld 2019 US is to continue discussions with partners, customers, and internal teams about how a benchmark like VMmark ML would be most useful. We also hope to complete our integration of Spark within Kubernetes on vSphere and reproduce some of the performance analysis done to date. Stay tuned to the performance blog for additional posts and details as they become available.
