![]() ![]() ![]() The guiding principle in the design of Nemesis was to structure the operating system in such a way that the majority of code could execute in the application process itself. In a kernel-based system, multimedia applications spend most of their time in the kernel, leading to similar problems. This leads to enormous difficulty in accounting for resource usage. In a microkernel environment like Nemesis’, an application is typically implemented by a number of processes, most of which are servers performing work on behalf of more than one client. Screenshots are available but read more for information and status of this interesting operating system. The OS has been built with the Multimedia in mind, its sole purpose of existance was the delivery and performance of multimedia content in the best way possible. Nemesis provides fine-grained guaranteed levels of all system resources including CPU, memory, network bandwidth and disk bandwidth. Nemesis is an operating system written from scratch (but it does retain some Posix compatibility layer for easy application porting), whose design is geared to the support of time-sensitive applications requiring a consistent ‘Quality of Service’ (QoS), such as those which use multimedia.
