Abstract

Ada 2012 has introduced mechanisms for exploiting multiprocessor platforms at the application level. These include task affinity control and definition of dispatching domains. However, there are other executable entities defined in the language for which there is no such support to affinity control: event handlers. With event handlers we mean both timing-event and interrupt handlers. This paper discusses the consequences of this lack of functionality and explores implementation issues related with this ability. We propose a working implementation for affinity of timing-event handlers on top of Linux.
