Distributed Control System
Blue Gene/Q supports a load balancing clustering model. This chapter describes a centralized load balancing cluster for distributing service node bandwidth and CPU utilization using a single service node or over multiple smaller nodes. This model focuses on splitting up the mc_server process and managing it with a distributed process manager.
Performance measurements show that the mc_server software component is, by far, the largest consumer of CPU and networking bandwidth, especially during block booting. ...
