Chapter 9 System utilities

Each V-Class server has a section of hardware known as the Exemplar Core Utilities board (ECUB) located on the ENRB. On the ECUB are two FPGAs: the Exemplar Processor Utilities (EPUC) and the Exemplar Monitoring Utilities (EMUC). The EPUC provides the ECUB a means to send interrupts and error messages to the processors and to receive control messages from the processors. The EMUC performs all environmental monitoring. The ECUB board connects to all EPACs through the core logic bus.
