Microcontroller based distributed and networked control system for public cluster

TL;DR

This paper introduces a networked distributed control system for public clusters, enabling remote power management of nodes via a web interface to extend hardware lifespan and reduce costs.

Contribution

It presents a novel architecture for distributed control in public clusters, integrating master and node controllers connected through RS-485 for networked power management.

Findings

Successful implementation at LIPI Public Cluster

Enhanced control accessibility via web interface

Potential for extending hardware lifetime and reducing costs

Abstract

We present the architecture and application of the distributed control in public cluster, a parallel machine which is open for public access. Following the nature of public cluster, the integrated distributed control system is fully accessible through network using a user-friendly web interface. The system is intended mainly to control the power of each node in a block of parallel computers provided to certain users. This is especially important to extend the life-time of related hardwares, and to reduce the whole running and maintainance costs. The system consists of two parts : the master- and node-controllers, and both are connected each other through RS-485 interface. Each node-controller is assigned with a unique address to distinguish each of them. We also discuss briefly the implementation of the system at the LIPI Public Cluster.
