LODAR: layered optimization for distributed adaptive LLM routing

Large language model (LLM) serving platforms increasingly route requests across heterogeneous backends, transforming query routing from a model-selection task into a system-level load-balancing problem. Centralized routers can become throughput bottlenecks and single points of failure as deployment scale and request vo...

A mathematical model for optimizing containerized deployment in energy-efficient virtualized data centers: SAP HANA datacenter simulation

This study addresses the challenge of efficient resource management in data centers through pod and virtual machine (VM) migration. The objective is to prevent resource shortages while improving power efficiency in cloud environments. To this end, we formulate a multi-objective mixed-integer linear programming (MILP) m...
