Node-Level Diffusion Workflow Offloading for Faster Image Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current diffusion-based image generation models require high computational resources, leading to inefficient processing times and infeasibility on devices with constrained hardware capabilities, particularly when CPU-based execution is used.
Innovation Solution
A workflow is partitioned at the node-level to offload computationally intensive nodes to remote higher-end processing resources (e.g., GPUs) while less intensive nodes are processed locally using lower-end CPUs, maintaining data consistency through intelligent preprocessing and categorization of input parameters.

Engineering Contradiction Analysis
1Productivity
If diffusion-based image generation is executed using CPU-only methods, then device compatibility is maintained, but processing time is excessive and throughput is limited
Solution Approach 1:
The workflow is divided into multiple nodes representing different processing stages. Computationally intensive nodes are identified and separated from less intensive nodes, allowing selective offloading to remote GPUs while keeping simpler operations local to CPU devices.
Solution Approach 2:
A hybrid processing architecture is introduced that acts as an intermediary between local CPU execution and remote GPU resources. The system intelligently routes specific workflow nodes to appropriate processing resources, combining local and remote capabilities to optimize both speed and accessibility.
2Speed
If computationally intensive nodes are offloaded to remote GPUs, then processing speed improves, but system complexity increases
Solution Approach 1:
The system design allows the same workflow execution engine to operate in multiple modes: purely local CPU execution, purely remote GPU execution, or hybrid execution. This multi-functionality enables flexible adaptation to different user needs and resource availability without requiring separate systems.
Solution Approach 2:
The system performs preliminary analysis of the workflow to identify which nodes are computationally intensive and would benefit from GPU acceleration. This pre-processing of the workflow structure allows intelligent routing decisions to be made before execution, reducing runtime complexity.

AI summary
Examples are disclosed relating to generating a synthesized image using a diffusion model in a manner that improves processing resource usage efficiency. In one example, a computing device is configured to execute a local diffusion engine that is configured to process a plurality of nodes in a workflow to generate a synthesized image using the diffusion model. The local diffusion engine is configured to, for each node that is labeled with a designation to be processed by a remote diffusion engine, capture input data for the node from the workflow, construct a node-specific workflow based on the input data, send the node-specific workflow to the remote diffusion engine, and receive output data generated by the remote diffusion engine based on processing the node-specific workflow. The output data is used to process a node of the workflow. The local diffusion engine is configured to output the synthesized image.
