Description:
------------
Real-time intensive signal processing applications have been traditionally
deployed on various custom platforms. Meanwhile, the enterprise computing
market had spurred the advent of inexpensive and powerful systems based on
widely available processors. Today, SMP systems associating a potentially
large number of recent processors are deemed to cope with the needs of the
most demanding real-time applications. On the operating system side, GNU/Linux
is gaining wider acceptance and extending GNU/Linux to tackle real-time
application scheduling is a common approach.
We propose ARTiS, an asymmetric real-time scheduling for SMP systems. ARTiS
ensures the possible preemption of a processor when the system has to sc!
hedule a real-time process.
We have modified the GNU/Linux SMP scheduler to implement ARTiS. The first
implementation has run as a modified 2.4 GNU/Linux kernel on Intel IA-32
systems. An evaluation of this approach shown significant improvements.
The current version of ARTiS extends our first model and targets both ix86 and
IA-64 SMP platforms.
This work is conducted in the frame of the ITEA project #01010, HYADES.
