Abstract

This paper presents an application program interface (API) that enables applications running on top of a POSIX operating system to use application-defined scheduling algorithms in a way compatible with the scheduling model of the Ada 95 Real-Time Systems Annex. Several application-defined schedulers, implemented as special user tasks, can coexist in the system in a predictable way. This API is currently implemented on our operating system MaRTE OS.
