Rivas M.A., Harbour M.G. (2002) A POSIX-Ada Interface for Application-Defined Scheduling. In: Blieberger J., Strohmeier A. (eds) Reliable Software Technologies — Ada-Europe 2002. Ada-Europe 2002. Lecture Notes in Computer Science, vol 2361. Springer, Berlin, Heidelberg
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.
