  abstract= "Virtuoso Classico /VSP is a fully distributed real-time
     operating system originally developed on the INMOS
     transputer. Its generic architecture is based on a small but
     very fast nanokernel and a portable preemptive microkernel.
     It was further on ported in single and virtual single
     processor implementations to a wide range of processors. As
     the basis of any real-time application is a scheduler that
     allows the developer to use the minimum schedule to satisfy
     the real-time requirements, a number of derived Virtuoso
     tools have been developed with complementary
     functionalities. This paper describes the rationale for
     developing the distributed semantics of Virtuoso's
     microkernel and describes some of the implementation issues.
     The analysis is based on the parallel DSP implementations as
     these push the performance limits most for hard real-time
     applications. The Virtuoso tools are being ported and
     further developed in the DIPSAP-II and EURICO OMI/Esprit
