Power-aware RoCE Edge Transfer Agent

This study presents a novel software module, internally developed to optimize Remote Direct Memory Access (RDMA) transfers for both performance and energy efficiency. It is possible to design an Energy Aware RDMA Transfer Agent (E-RTA) to intelligently detect RDMA-capable hardware on both ends of a transfer and adjust key parameters such as buffer sizes in real time. E-RTA communicates with higher-level controllers and lower-level hardware to create a dynamic and responsive data transfer environment. Initial benchmarking using this agent reveals that RDMA writing operations consistently achieve lower latency compared to other RDMA modes and traditional TCP-based methods. To address energy concerns, the module also estimates power consumption during transfers, using CPU load and thermal metrics obtained through Prometheus and visualized via Grafana dashboards. The integrated design offers a promising direction for building adaptive, energy-aware high-performance data pipelines.
