Abstract
This paper describes a real­time extension to Linux
called LITMUS RT , which is being designed to support
real­time workloads on multiprocessor and multicore
platforms. The recent shift by chip makers to multi­
core designs, combined with building interest within the
open­source community in supporting real­time features
in Linux, makes this research quite timely. The devel­
opment of LITMUS RT was driven by a desire to bridge
the gap between those working on algorithmic issues
pertaining to multiprocessor real­time resource alloca­
tion and operating­systems researchers working to im­
prove real­time support within operating systems such
as Linux.
