To handle massively parallel systems and make them usable, an adaptive, application-oriented operating system is required. The application orientedness is represented by the family concept of parallel operating systems. Incremental loading of operating system services supports the family character by automatically extending the system's active object structure when it is necessary. This way, also the switching between different operating system family members may be realized. A new active object will be incrementally loaded if its invocation fails because it does not yet exist. This is noticed during object binding while using the naming services. The use of the naming system is exploited and extended to get a flexible and configurable mechanism for triggering incremental loading. This mechanism is built by the freely definable naming strategies and exceptions that result again in a family, namely a family of naming services.

This article presents an overview of PUMA (Performance-oriented, User-managed Messaging Architecture), a message-passing kernel for massively parallel systems. Message passing in PUMA is based on portals – an opening in the address space of an application process. Once an application process has established a portal, other processes can write values into the portal using a simple send operation. Because messages are written directly into the address space of the receiving process, there is no need to buffer messages in the PUMA kernel and later copy them into the applications address space. PUMA consists of two components: the quintessential kernel (Q-Kernel) and the process control thread (PCT). Although the PCT provides management decisions, the Q-Kernel controls access and implements the policies specified by the PCT.
