MultiGPU_Options - ComfyUI Built-in Node Documentation

Overview

This node allows you to specify the relative performance of each GPU when using multiple graphics cards with different speeds. It creates a group of GPU options that can be used to distribute work across devices, though the actual speed-based workload distribution is not yet implemented in the current version.

Inputs

Parameter	Description	Data Type	Required	Range
`device_index`	The index number of the GPU device to configure (default: 0)	INT	Yes	0 to 64
`relative_speed`	The relative speed of this GPU compared to others, used for workload distribution (default: 1.0, step: 0.01)	FLOAT	Yes	0.0 to unlimited
`gpu_options`	An existing GPU options group to add this device’s options to. If not provided, a new group is created	GPU_OPTIONS	No	-

Outputs

Output Name	Description	Data Type
`GPU_OPTIONS`	A group of GPU options containing the configured device settings, which can be passed to other nodes for multi-GPU operations	GPU_OPTIONS

Note: The relative_speed parameter is defined but not yet used by the internal scheduler for distributing work across GPUs. In the current implementation, work is distributed evenly across all devices regardless of their relative speeds.
