UTH FPGA Telemetry Dataset for ML Inference Experiments on AMD/Xilinx ZCU102 MPSoC Development Board

📌 Overview This dataset contains telemetry traces from repeated machine learning inference experiments executed on a Xilinx ZCU102 FPGA platform.Each experiment corresponds to a specific DPU bitstream configuration (DPU size and number of DPU compute units), a model variant (including pruning variants), and a system workload mode applied on the ARM CPU. The dataset is intended to support research on: FPGA-based ML inference performance, DPU scaling and configuration trade-offs, interaction between FPGA accelerators and ARM CPU workloads, power, memory bandwidth, and system-level telemetry analysis. Each experiment produces a time-series telemetry trace recorded during a batch inference run. 📂 Dataset Structure The dataset is organized into two main components: experiments.csv — index fileOne row per experiment run, describing its configuration. data/<experiment_id>.csv — telemetry traceTime-series telemetry recorded during the corresponding experiment. 🗂️ experiments.csv — Index File experiments.csv is the entry point to the dataset.Each row describes one complete experiment run on the FPGA. Format Experiment ID,DPU CU#,DPU Size,Model,Workload Mode Index Columns Column Description Experiment ID Unique identifier for the experiment run. Used to locate the trace at data/<experiment_id>.csv. DPU CU# Number of DPU compute units (parallel inference threads). DPU Size DPU configuration size. The dataset includes 8 sizes and 26 total configurations when combined with CU counts. Model Model executed during the experiment. Pruning variants are encoded in the name (e.g., resnet18-25 for 25% pruning). Workload Mode Background workload on the ARM CPU: None, C-H (compute-bound), or M-H (memory-bound). 🧪 Experiments Overview Aspect Description Hardware platform Xilinx ZCU102 MPSoC Development Board DPU configurations 26 total (8 DPU sizes × multiple CU counts) Models 12 models with pruning variants (-25, -50, or none) Run duration From seconds up to ~10 minutes Execution mode Batch inference Each row in experiments.csv corresponds to one full experiment run on the development board. 📈 Telemetry Traces — data/<experiment_id>.csv Each telemetry file contains a time series of system and inference measurements recorded during the experiment. Time Columns Column Description timestamp Unix timestamp (seconds, fractional) when the telemetry row was recorded. timestamp_human Human-readable timestamp of the same moment. These represent the actual time at which telemetry was sampled. Per-Thread Performance Columns (*_K) Many columns are indexed by K, representing per-DPU compute unit (per inference thread) measurements.K ranges from 1 to DPU CU#. Column Pattern Description preprocessing_time_K Preprocessing latency for inference thread K. inference_time_K Inference latency for thread K. postprocessing_time_K Postprocessing latency for thread K. job_id_K Identifier of the inference job executed on thread K. fps_K Frames-per-second observed for thread K. Memory Bandwidth Telemetry (ZCU102 Ports) Column Description S0_read … S4_read Read bandwidth for memory ports 0–4. S0_write … S4_write Write bandwidth for memory ports 0–4. Power Telemetry Column Description arm_power Instantaneous power consumption of the ARM CPU subsystem. fpga_power Instantaneous power consumption of the FPGA fabric. CPU Utilization (ARM Cortex-A53) Column Description cpu_0, cpu_1, cpu_2, cpu_3 Utilization of the four ARM Cortex-A53 cores. Memory Metrics Column Description memory_available Available system memory at sampling time. memory_total Total system memory. swap_free Free swap space. Experiment Linkage Column Description experiment_id Experiment identifier matching the filename and the index in experiments.csv. 🚀 How to Use the Dataset Select an experiment from experiments.csv based on: DPU configuration (DPU Size, DPU CU#) model variant (Model) workload mode (Workload Mode) Open the corresponding telemetry trace: data/<experiment_id>.csv Analyze: inference latency breakdown (pre / infer / post), per-thread throughput (fps_K), memory bandwidth usage (S*_read, S*_write), CPU utilization and power behavior under different workloads. 🎯 Intended Use This dataset is intended for: FPGA performance analysis, ML inference benchmarking, system-level telemetry studies, research on accelerator–CPU interaction. It represents a controlled experimental environment, not a production deployment. 🤝 Acknowledgements & Funding This work is part of the MLSysOps project and is funded by the European Union’s Horizon Europe research and innovation programme under grant agreement No. 101092912.
