Real-time control and monitoring system for LIPI's Public Cluster

We have developed a monitoring and control system for LIPI's Public Cluster. The system consists of microcontrollers and full web-based user interfaces for daily operation. It is argued that, due to its special natures, the cluster requires fully dedicated and self developed control and monitoring system. We discuss the implementation of using parallel port and dedicated micro-controller for this purpose. We also show that integrating such systems enables an autonomous control system based on the real time monitoring, for instance an autonomous power supply control based on the actual temperature, etc.
