My Picks for NVIDIA GTC Spring 2023

March 21, 2023 by frankdenneman

This week GTC Spring 2023 kicks off again. These are the sessions I look forward to next week. Please leave a comment if you want to share a must-see session.


MLOps

Title: Enterprise MLOps 101 [S51616]

The boom in AI has seen a rising demand for better AI infrastructure — both in the compute hardware layer and AI framework optimizations that make optimal use of accelerated compute. Unfortunately, organizations often overlook the critical importance of a middle tier: infrastructure software that standardizes the machine learning (ML) life cycle, adding a common platform for teams of data scientists and researchers to standardize their approach and eliminate distracting DevOps work. This process of building the ML life cycle is known as MLOps, with end-to-end platforms being built to automate and standardize repeatable manual processes. Although dozens of MLOps solutions exist, adopting them can be confusing and cumbersome. What should you consider when employing MLOps? How can you build a robust MLOps practice? Join us as we dive into this emerging, exciting, and critically important space.

Michael Balint, Senior Manager, Product Architecture, NVIDIA

William Benton, Principal Product Architect, NVIDIA

Title: Solving MLOps: A First-Principles Approach to Machine Learning Production [S51116]

We love talking about deploying our machine learning models. One famous (but probably wrong) statement says that “87% of data science projects never make it to production.” But how can we get to the promised land of “Production” if we’re not even sure what “Production” even means? If we could define it, we could more easily build a framework to choose the tools and methods to support our journey. Learn a first-principles approach to thinking about deploying models to production and MLOps. I’ll present a mental framework to guide you through the process of solving the MLOps challenges and selecting the tools associated with machine learning deployments.

Dean Lewis Pleban, Co-Founder and CEO, DagsHub

Title: Deploying Hugging Face Models to Production at Scale with GPUs [S51553]

Seems like everyone’s using Hugging Face to simplify and reuse advanced models and work collectively as a community. But how do you deploy these models into real business environments, along with the required data and application logic? How do you serve them continuously, efficiently, and at scale? How do you manage their life cycle in production (deploy, monitor, retrain)? How do you leverage GPUs efficiently for your Hugging Face deep learning models? We’ll share MLOps orchestration best practices that’ll enable you to automate the continuous integration and deployment of your Hugging Face models, along with the application logic in production. Learn how to manage and monitor the application pipelines, at scale. We’ll show how to enable GPU sharing to maximize application performance while protecting your investment in AI infrastructure and share how to make the whole process efficient, effective, and collaborative.

Yaron Haviv, Co-Founder and CTO, Iguazio

Title: Democratizing ML Inference for the Metaverse [S51948]

In this talk, I will drive you through the Roblox ML Platform inference service. You will learn how we integrate Triton inference service with Kubeflow and Kserve. I will describe how we simplify the deployment for our end users to serve models on both CPU and GPUs. Finally, I will highlight few of our current cases like game recommendation and other computer vision models.

Under the first direction, we highlight the features and performance of the MVAPICH2-DPU library in offloading non-blocking collective communication operations to the DPUs. Under the second direction, we demonstrate how some parts of computation in DNN training can be offloaded to the DPUs. We’ll present sample performance numbers of these designs on various computing platforms (x86 and AMD) and Bluefield adapters (HDR-100Gbps and HDR-200 Gbps), along with some initial results using the newly proposed cross-GVMI support with DPU.

Dhabaleswar K. (DK) Panda, Professor and University Distinguished Scholar, The Ohio State University

Title: Tuning Machine Learning and HPC Workloads Performance in Virtualized Environments using GPUs [S51670]

Today’s machine learning (ML) and HPC applications run in containers. VMware vSphere runs containers in virtual machines (VMs) with VMware Tanzu for container orchestration and Kubernetes cluster management. This allows servers in the hybrid cloud to simultaneously host multi-tenant workloads like ML inference, virtual desktop infrastructure/graphics, and telco workloads that benefit from NVIDIA AI and VMware virtualization technologies. NVIDIA AI Enterprise software in VMware vSphere combines the outstanding virtualization benefits of vSphere with near-bare metal, or in HPC applications, better than bare-metal performance. NVIDIA AI Enterprise on vSphere supports NVLink and NVSwitch, which allows ML training, and HPC applications to maximize multi-GPU performance. We’ll describe these technologies in detail, and you’ll learn how to leverage and tune performance to achieve significant savings in total cost of ownership for your preferred cloud environment. We’ll highlight the performance of the latest NVIDIA GPUs in virtual environments.

Simulating NUMA Nodes for Nested ESXi Virtual Appliances

March 2, 2023 by frankdenneman

To troubleshoot a particular NUMA client behavior in a heterogeneous multi-cloud environment, I needed to set up an ESXi 7.0 environment. Currently, my lab is running ESXi 8.0, so I’ve turned to William Lams’ excellent repository of nested ESXi virtual appliances and downloaded a copy of the 7.0 u3k version.

My physical ESXi hosts are equipped with Intel Xeon Gold 5218R CPUs, containing 20 cores per socket. The smallest ESXi host contains ten cores per socket in the environment I need to simulate. Therefore, I created a virtual ESXi host with 20 vCPUs and ensured that there were two virtual sockets (10 cores per socket)

Once everything was set up and the ESXi host was operational, I checked to see if I could deploy a 16 vCPU VM to simulate particular NUMA client configuration behavior and verify the CPU environment.
The first command I use is to check the “physical” NUMA node configuration “sched-stats -t numa-node“. But this command does not give me any output, which should not happen.

Let’s investigate, let’s start off by querying the CPUinfo of the VMkernel Sys Info Shell (vsish): vsish -e get /hardware/cpu/cpuInfo

The ESXi host contains two CPU packages. The VM configuration Cores per Socket has provided the correct information to the ESXi kernel. The same info can be seen in the UI at Host Configuration, Hardware, Overview, and Processor.

However, it doesn’t indicate the number of NUMA nodes supported by the ESXi kernel. You would expect that two CPU packages would correspond to at least two NUMA nodes. The command
vsish -e dir /hardware/cpuTopology/numa/nodes shows the number of NUMA nodes that the ESXi kernel detects

It only detects 1 NUMA node as the virtual NUMA client configuration has been decoupled from the Cores Per Socket configuration since ESXi 6.5. As a result, the VM is presented by the physical ESXi host as a single virtual NUMA node, and the virtual ESXi host picks this up. Logging in to the physical host, we can validate the nested ESXi VM configuration and run the following command.

vmdumper -l | cut -d \/ -f 2-5 | while read path; do egrep -oi "DICT.(displayname.|numa.|cores.|vcpu.|memsize.|affinity.)= .|numa:.|numaHost:." "/$path/vmware.log"; echo -e; done

The screen dump shows that the VM is configured with one Virtual Proximity Domain (VPD) and one Physical Proximity Domain (PPD). The VPD is the NUMA client element that is exposed to the VM as the virtual NUMA topology, and the screenshot shows that all the vCPUs (0-19) are part of a single NUMA client. The NUMA scheduler uses the PPD to group and place the vCPUs on a specific NUMA domain (CPU package).

By default, the NUMA scheduler consolidates vCPUs of a single VM into a single NUMA client up to the same number of physical cores in a CPU package. In this example, that is 20. As my physical ESXi host contains 20 CPU cores per CPU package, all the vCPUs in my nested ESXi virtual appliance are placed in a single NUMA client and scheduled on a single physical NUMA node as this will provide the best possible performance for the VM, regardless of the Cores per Socket setting.

The VM advanced configuration parameter numa.consolidate = "false” forces the NUMA scheduler to evenly distribute the vCPU across the available physical NUMA nodes.

After running the vmdumper instruction once more, you see that the NUMA configuration has changed. The vCPUs are now evenly distributed across two PPDs, but only one VPD exists. This is done on purpose, as we typically do not want to change the CPU configuration for the guest OS and application, as that can interfere with previously made optimizations.

You can do two things to change the configuration of the VPD, use the VM advanced configuration parameter numa.vcpu.maxPerVirtualNode and set it to 10. Or remove the numa.autosize.vcpu.maxPerVirtualNode = “20” from the VMX file.

I prefer removing the numa.autosize.vcpu.maxPerVirtualNode setting, as this automatically follows the PPD configuration, it avoids mismatches between numa.vcpu.maxPerVirtualNode and the automatic numa.consolidate = "false" configuration. Plus, it’s one less advanced setting in the VMX, but that’s just splitting hairs. After powering up the nested ESXi virtual appliance, you can verify the NUMA configuration once more in the physical ESXi host:

The vsish command vsish -e dir /hardware/cpuTopology/numa/nodes shows ESXi detects two NUMA nodes

and sched-stats -t numa-pnode now returns the information you expect to see

Please note that if the vCPU count of the nested ESXi virtual appliance exceeds the CPU core count of the CPU package, the NUMA scheduler automatically creates multiple NUMA clients.
