Deft Scheduling of Dynamic Cloud Workflows with Varying Deadlines via Mixture-of-Experts

Ya Shen, Gang Chen, Hui Ma, Mengjie Zhang
ICLR 2026poster

Workflow scheduling in cloud computing demands the intelligent allocation of dynamically arriving, graph-structured workflows with varying deadlines onto ever-changing virtual machine resources. However, existing deep reinforcement learning (DRL) schedulers remain limited by rigid, single-path infer…

GATES: Cost-aware Dynamic Workflow Scheduling via Graph Attention Networks and Evolution Strategy

Ya Shen, Gang Chen, Hui Ma, Mengjie Zhang
IJCAI 2025

Cost-aware Dynamic Workflow Scheduling (CADWS) is a key challenge in cloud computing, focusing on devising an effective scheduling policy to efficiently schedule dynamically arriving workflow tasks, represented as Directed Acyclic Graphs (DAG), to suitable virtual machines (VMs). Deep reinforcement
