CoreManager is a singleton class which should be configured with a list of CPU cores available to the application. Threads that require exclusive access to a CPU core can then request a core from the CoreManager which will allocate one of the cores from its list and set the CPU affinity of the current thread. If no spare cores are available an exception will be thrown. CoreManager keeps track of which module the core was allocated to in a map, terminating threads should inform CoreManager via the release method.
In this scheme, before instantiating DAQ modules, the application
framework obtains the available core information from OKS and
initialises CoreManager. Individual DAQ modules should then request
cores for exclusive use by their threads by calling
CoreManager::allocate() during initialisation and the threads
themselves should call CoreManager::setAffinity() to set affinity to
their allocated CPUs.
