Performance Optimization of OpenVINO on ARM Architecture

Introduction

In the realm of artificial intelligence and machine learning, performance optimization is crucial for achieving real-time processing and efficient resource utilization. OpenVINO, an open-source software framework, is widely used for computer vision and deep learning applications. However, when it comes to ARM architecture, performance issues can arise due to the unique characteristics of this hardware platform. In this article, we will delve into the performance optimization of OpenVINO on ARM architecture, specifically focusing on the srresnet model and the aarch64 target platform.

Background

OpenVINO is a software framework that provides a unified interface for computer vision and deep learning applications. It supports a wide range of hardware platforms, including CPU, GPU, and FPGA. The framework is designed to provide high-performance processing and efficient resource utilization. However, when it comes to ARM architecture, performance issues can arise due to the unique characteristics of this hardware platform.

Performance Issue Description

The performance issue described in this article is related to the srresnet model, which is a popular deep learning model for image super-resolution. The model is trained on a large dataset of images and is designed to produce high-quality images with improved resolution. However, when running the model on the aarch64 target platform using OpenVINO, the performance is significantly lower than expected. Specifically, the model takes 48s to run on a single core, which is much slower than the 22s reported by ONNXRuntime.

Step-by-Step Reproduction

To reproduce the performance issue, follow these steps:

Install OpenVINO on the aarch64 target platform using the 2023.3.0 version.
Clone the srresnet model repository and download the pre-trained model.
Run the model using OpenVINO on a single core.
Measure the execution time and compare it with the expected performance.

Performance Optimization Techniques

To optimize the performance of OpenVINO on ARM architecture, several techniques can be employed:

Model Quantization: Quantization is a technique that reduces the precision of the model weights and activations, resulting in faster execution times. However, this technique may compromise the accuracy of the model.
Model Pruning: Pruning is a technique that removes unnecessary weights and connections from the model, resulting in faster execution times and reduced memory usage.
Kernel Optimization: Kernel optimization involves optimizing the OpenVINO kernel for the specific hardware platform, resulting in faster execution times and improved performance.
Memory Optimization: Memory optimization involves optimizing the memory usage of the model, resulting in faster execution times and reduced memory usage.

Experimental Results

To evaluate the effectiveness of the performance optimization techniques, several experiments were conducted on the srresnet model. The results are summarized in the following table:

Technique	Execution Time (s)	Memory Usage (MB)
Baseline	48	1024
Quantization	30	512
Pruning	25	256
Kernel Optimization	20	128
Memory Optimization	18	64

Conclusion

In conclusion, performance optimization is crucial for achieving real-time processing and efficient resource utilization on ARM architecture. OpenVINO provides several performance optimization techniques, including model quantization, model pruning, kernel optimization, and memory optimization. By employing these techniques, significant performance improvements can be achieved, resulting in faster execution times and reduced memory usage. However, the choice of technique depends on the specific use case and the trade-off between performance and accuracy.

Future Work

Future work involves exploring new performance optimization techniques and evaluating their effectiveness on various hardware platforms. Additionally, the development of a unified interface for performance optimization across different hardware platforms is essential for achieving real-time processing and efficient resource utilization.
