Scheduler Plugins

Scheduler Plugins maintains multiple plugins used to differentiate the scheduling strategies for different workloads.

Plugin List

ResourceFungibility Plugin

A llama2-7B model can be running on 1xA100 GPU, also on 1xA10 GPU, even on 1x4090 and a variety of other types of GPUs as well, that's what we called resource fungibility. In practical scenarios, we may have a heterogeneous cluster with different GPU types, and high-end GPUs will stock out a lot, to meet the SLOs of the service as well as the cost, we need to schedule the workloads on different GPU types.

With resourceFungibility plugin, we can simply achieve this with at most 8 alternative GPU types.

In the future, we need to explore the GPU usage dynamically, not only for the availability and cost, but also the performance. See related paper about Mélange: Cost Efficient Large Language Model Serving by Exploiting GPU Heterogeneity.
