A RapiDaemon is an application designed to create contention in a predictable and controlled manner on a specific shared resource in a multicore system. The effect of this contention can then be measured to identify interference channels and impacts on execution times.
Rapita have developed and optimized a set of standard RapiDaemons that target shared resources common to most multicore architectures, such as main memory. Some projects will require the creation of custom RapiDaemons for a specific architecture.
