What You Need to Know About MLCommons, MLPerf, and AI Benchmarking

A benchmarking suite such as MLPerf from MLCommons plays an important role in GenAI Performance and Infrastructure. MLPerf lets enterprises make data-driven decisions about their GenAI infrastructure by evaluating GenAI training, inference, and storage performance. Let’s dive into the subject of benchmarking suites and why you might want to consider using one.

1. Understanding MLPerf and Its Role in AI Benchmarking

MLPerf, developed by MLCommons, is the industry-standard AI benchmarking suite​. It provides vendor-neutral performance comparisons across different AI hardware, ensuring enterprises don’t rely solely on vendor claims when making purchasing decisions.

Key Divisions of MLPerf:

MLPerf offers a comprehensive benchmarking suite that evaluates AI system performance across various workloads. It includes MLPerf Training, which measures how quickly AI models can be trained on different hardware platforms, and MLPerf Inference, which assesses the efficiency of GenAI models in making real-time predictions. Additionally, MLPerf Storage benchmarks the performance of storage systems in GenAI workflows, ensuring that data movement matches compute demands. Combined, these benchmarks assist organizations in optimizing their AI infrastructure for speed, efficiency, and effectiveness scalability.

Specific MLPerf Metrics 

MLPerf Key Performance Metrics:

• Time-to-train (TTT): Measures how quickly a model reaches a target accuracy

• Samples per second: Critical for inference workloads

• Throughput under various batch sizes

• Power efficiency metrics (MLPerf Power)

• Resnet-50, BERT, and other standard model benchmarks with specific quantitative targets.

2. MLPerf Categories Expansion: I would add a dedicated subsection:

MLPerf Benchmark Categories:

• Data Center Training: For large-scale model development

• Data Center Inference: For cloud and enterprise deployments

• Edge Inference: For mobile and IoT devices

• HPC: For scientific computing workloads

• Tiny: For ultra-low-power devices

• Mobile: For smartphone and tablet environments."

Why CIOs Should Care

AI workloads are different from traditional enterprise workloads. GenAI models require:

• High-bandwidth data access to keep GPUs and AI accelerators busy.

• Low-latency storage to avoid compute idle time.

• Efficient GPU utilization to maximize return on investment.

Organizations risk poor infrastructure choices without proper benchmarking, leading to wasted AI spending and bottlenecked performance.

2. MLPerf Storage: Why Storage is Critical in AI Workloads

Enterprises often neglect storage in favor of AI computing power (GPUs, TPUs, CPUs). ML workflows can be improved or hampered by storage performance.

Common AI Storage Bottlenecks

Storage performance is a critical yet often overlooked factor in GenAI workloads. Training models require streaming massive datasets, but traditional storage solutions frequently fail to keep up with the high-speed data demands of GPUs. GenAI training slows down with insufficient storage throughput, leading to inefficient resource utilization.

For GenAI inference workloads, ultra-low-latency data access is essential to ensure real-time predictions. However, high network overhead and slow storage retrieval times create bottlenecks that delay responses, making GenAI applications less effective in time-sensitive scenarios. Additionally, storage inconsistencies can lead to non-reproducible AI results, affecting compliance, reliability, and overall model accuracy. GenAI deployments risk inefficiencies that undermine performance and scalability without an adequately optimized storage infrastructure.

How MLPerf Storage Benchmarks Help

To tackle these challenges, MLPerf Storage offers standardized benchmarks that assess storage performance in GenAI environments. It evaluates throughput and bandwidth, measuring how effectively data can be supplied to GenAI accelerators to avoid compute stalls. Additionally, it tests latency and IOPS, ensuring that real-time AI workloads can access data quickly without causing bottlenecks.

Another critical metric is scalability and consistency, which determine whether a storage system can handle increasing GenAI workloads without performance degradation. By utilizing MLPerf Storage benchmarks, enterprises can make informed decisions about their storage infrastructure, ensuring it meets the demands of modern AI workloads while maintaining efficiency and reliability.

3. The Hidden Cost: GPU Inefficiencies in AI Workloads

One of the biggest obstacles to AI investment is poor GPU utilization. Enterprises spend millions on GPUs, yet studies show that GPU utilization often remains below 15%​.

Why GPUs Are Underutilized in AI Workloads

Many enterprises struggle to fully harness their GPUs, leading to significant inefficiencies and wasted investments. One major issue is ineffective scheduling and workload distribution, where GPU job queues are not optimized, resulting in delays and underutilization. Furthermore, memory fragmentation and inadequate batch processing lead to wasted GPU memory, preventing models from operating at their full capacity. Another critical bottleneck is slow data pipelines, where GPUs remain idle, waiting for data to be ingested, processed, and made available for computation. These inefficiencies result in lower performance, increased costs, and extended AI development cycle workloads.

How MLPerf Helps Identify GPU Inefficiencies

MLPerf benchmarks provide essential insights into GPU utilization, assisting organizations in identifying and resolving performance bottlenecks. By evaluating AI system limitations, MLPerf highlights slow data transfer, ineffective memory management, and inadequate workload balancing, all leading to underused GPUs. Moreover, MLPerf provides vendor-neutral performance comparisons, enabling CIOs to make informed decisions based on efficiency rather than solely on hardware costs. These benchmarks support organizations in optimizing their AI infrastructure, ensuring that GPUs achieve maximum performance without unnecessary overhead.

How CIOs Can Fix GPU Inefficiencies

To enhance GPU efficiency, CIOs can employ several essential strategies. Implementing CPU offloading allows AI workloads to transfer memory-intensive tasks to CPUs, freeing up GPU resources for computation. Utilizing GPU-aware storage solutions, such as NVIDIA GPUDirect Storage, facilitates direct data transfers between storage and GPUs, reducing bottlenecks and boosting overall performance. Automating real-time monitoring with tools like nvidia-smi and MLPerf benchmarks enables organizations to continuously track and optimize GPU usage, ensuring that inefficiencies are identified and resolved in production environments. By leveraging these strategies, enterprises can maximize their GPU investments and improve AI performance.

4. Strategic Takeaways for CIOs

Storage Infrastructure: Storage performance is as critical as computing power in AI workloads. Without an optimal storage architecture, even the most potent accelerators will underperform due to data starvation. GPU Optimization: Prioritizing maximum GPU utilization is essential. Regularly monitoring and optimizing GPU usage patterns can significantly enhance returns on AI infrastructure investments. Vendor Selection: When assessing AI hardware vendors, always request MLPerf-compliant benchmark results. These standardized metrics provide objective comparison benchmarks across different solutions. Scalability Planning: Utilize MLPerf benchmarks to strategize for future scaling. 

Understanding performance characteristics under Diverse workloads helps prevent infrastructure bottlenecks as AI deployments grow. Cost Optimization: Balance infrastructure investments across computing, storage, and networking based on MLPerf insights rather than concentrating solely on GPU capabilities. These enhancements would make the article more specific, actionable, and valuable for its target audience of CIOs and technical decision-makers. Would you like me to elaborate on any of these suggested improvements?
