PairSight: Characterizing and Predicting Operator-Level Interference in GPU Sharing for DNN Inference

First page of PairSight: Characterizing and Predicting Operator-Level Interference in GPU Sharing for DNN Inference
From the original paper · arXiv 2610.23086Page 1. Select the image to read the PDF.

PairSight replaces binary compute-memory rules, standalone scaling curves, and model-level predictors used to estimate interference when co-locating DNN inference tasks on one GPU, using hardware-counter-based operator-level modeling of shared-memory-path contention. The cost is a profiling and training pipeline: collecting hardware counters for operator pairs, training the predictor, and integrating its predictions into a scheduler, which adds engineering complexity beyond simple heuristics. It can fail if the reader's serving stack lacks counter access (e.g., third-party APIs), if co-location pairs differ from profiled hardware behavior, or if the reader only ever runs one model per GPU, in which case there is no interference to predict.

For solo builders

A possible application for this research area. Paper-specific feasibility still needs a full-paper review.

Your inference service slows down when several customers send requests together.

What you would change

Replay a recorded request trace with only the proposed serving policy changed.

Try the idea on your product

A proposed first test. Set your budget and success criteria before running it.

Replay a recorded request trace with only the proposed serving policy changed.

Compare against

Your current scheduler on the same model and hardware.

  1. Locate the paper's implementation and check its license, model support, data needs, and hardware requirements. Stop here if you cannot obtain the required artifacts.
  2. Save a small set of representative product tasks and expected outcomes. Keep evaluation tasks out of any training or tuning, and choose quality and cost limits before running.
  3. Run the baseline and the proposed change on identical inputs. Keep other settings fixed and repeat paired runs to expose variation.
  4. Save per-task outputs, failures, timings, and all usage costs. Review regressions before expanding the test.

What to measure

Requests meeting your latency target, throughput, failures, and cost per successful request.

When to keep it

Keep the change only if it meets your preselected quality and latency limits and improves the metric you care about after setup and operating costs. Otherwise retain the baseline. This is an exploration plan, not a validated recommendation.

The method is directly relevant to maximizing a single 24 GB GPU through co-location, but its value depends on whether the reader actually shares the GPU across tasks and can access the required hardware counters, so workload-specific validation is warranted before adoption.

    Read the brief interpretation

    PairSight replaces binary compute-memory rules, standalone scaling curves, and model-level predictors used to estimate interference when co-locating DNN inference tasks on one GPU, using hardware-counter-based operator-level modeling of shared-memory-path contention. The cost is a profiling and training pipeline: collecting hardware counters for operator pairs, training the predictor, and integrating its predictions into a scheduler, which adds engineering complexity beyond simple heuristics. It can fail if the reader's serving stack lacks counter access (e.g., third-party APIs), if co-location pairs differ from profiled hardware behavior, or if the reader only ever runs one model per GPU, in which case there is no interference to predict.

    This is a Paperraft inference. It is not pinned to a verified PDF passage.

  2. claim 02Paperraft inference

    PairSight predicts per-task latency under GPU co-location with 4.3% mean error, versus 19.0% for a compute-memory intensity rule, and adapts to unseen models and inputs with a few samples.

    This is a Paperraft inference. It is not pinned to a verified PDF passage.
