A set of nodes for ComfyUI that can composite layer and mask to achieve Photoshop like functionality.
The LayerUtility: PurgeVRAM node is a component within the ComfyUI that helps manage system resources, specifically video RAM (VRAM), which is critical for graphics-intensive tasks. This node provides users with a mechanism to clear VRAM, potentially improving system performance and freeing resources that might be locked or consumed by other processes.
The primary function of the LayerUtility: PurgeVRAM node is to clear the GPU's VRAM. This is particularly useful in cases where VRAM is consumed by previously loaded models or when there may be memory leaks causing inefficiencies in resource use. This node can also be configured to purge loaded models from memory to further conserve resources.
The LayerUtility: PurgeVRAM node accepts the following inputs:
anything: This input acts as a passthrough. It does not affect the functionality but allows the node to integrate seamlessly into data pipelines within ComfyUI workflows.
purge_cache: A boolean input that determines whether to clear intermediate cached data. It defaults to True. When enabled, it helps ensure all unnecessary cached data is removed from VRAM.
purge_models: Another boolean input that indicates whether to unload all models currently occupying VRAM. It also defaults to True, releasing more memory by removing model data.
The LayerUtility: PurgeVRAM node does not produce any outputs. It serves as a utility node that influences system resources rather than processing or transforming input data to generate outputs.
The LayerUtility: PurgeVRAM node can be instrumental in scenarios where managing GPU resources is critical:
Preparation for New Tasks: Before executing a new set of tasks that require significant VRAM, users can insert this node in the workflow to free up VRAM and minimize the risk of memory-related errors.
Resource Optimization: Developers and designers using ComfyUI can use the node to ensure that VRAM is not being inefficiently utilized by keeping obsolete data loaded.
Maintenance and Troubleshooting: This node can be particularly useful during debugging processes where VRAM consumption may be a contributing factor to performance issues.
Passthrough Functionality: The anything input allows this node to function as part of a more extensive workflow without disrupting data flow.
Customizability: With options to purge the cache and models independently, users have the flexibility to clear VRAM according to their specific needs.
Output Node: It is noteworthy that the node is an OUTPUT_NODE, meaning it typically acts as a terminator within certain processes in the workflow where clearing resources is the final desired action.
Version Availability: There is a V2 version of this node with similar functionality, which might include minor adjustments or improvements.
Thus, the LayerUtility: PurgeVRAM node is pivotal in maintaining the smooth operation of GPU-based processes within the ComfyUI by effectively re-managing VRAM use. While it does not process data to deliver outputs, its indirect impact on VRAM management is crucial for optimal system performance.
