Rapid reaction Linux: Linux with low latency and high timing accuracy
Arnd Heursch, Helmut Rzehak · 2001
Rapid Reaction Linux has been created at the University of German Federal Armed Forces in order to enhance realtime capabilities of the standard Linux kernel. Rapid Reaction Linux combines two well known patches to achieve this goal on the Intel x86 architecture using processors like Intel Pentium or any newer descendant. Rapid Reaction Linux combines the LOWLATENCY Patch [Molnar00], provided by Ingo Molnar, which has been found to reduce long latencies in the Linux kernel, with the UTIME Patch [Kansas97] of Kansas University that improves the precision of standard Linux timing services. Rapid Reaction Linux is not related to the well known KURT Linux [KURT98], except for the UTIME patch, both systems are relying on.
