Ok, maybe I had a wrong idea of how OpenMP works. I thought that the thread handling is realized somehow within OpenMP without the need for an operating system, because in the end you run an application directly on top of the hardware without an OS in between... Let's assume I'll take uClinux, what are the additional steps I have to take? Once again: many thanks for your patience!!!
