Mixture-of-Parallelisms: Towards Memory-Efficient Training Stack for Mixture-of-Experts Models
arXiv:2607.01844v1 Announce Type: cross Abstract: This paper showcases a memory-efficient training stack for Mixture-of-Experts (MoE) models. It is a training paradigm that combines and specializes various existing and novel parallelism techniques at different layers and stages of the Mixture-of-Experts (MoE) model training pipeline. It leverages these techniques to achieve maximal efficiency given the physical constraints of CPU, CPU memory, GPU HBM memory, and the CPU-GPU, GPU-GPU, and node-node communication bandwidth of the GPU cluster. It also contains a novel strategy for the optimizer s
The increasing scale and complexity of Mixture-of-Experts (MoE) models are pushing current training infrastructure to its limits, necessitating new memory-efficient paradigms.
Memory-efficient training stacks are critical for scaling advanced AI models, impacting the cost, accessibility, and environmental footprint of developing state-of-the-art AI.
This research introduces methods to significantly optimize the memory and compute resources required for training large MoE models, potentially broadening access to advanced AI development.
