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