Have you tried running the latest low-latency kernel, with modified settings in /etc/security/limits.conf? Frank
This is my limits.conf @usrp - rtprio 90 @usrp - memlock 2048000 @usrp - nice -19 The user running the code is in usrp group. I'm running kernel 2.6.20-0119.rt8 from http://people.redhat.com/mingo/realtime-preempt/. (Ingo Molnar's realtime preempt kernel) The scheduling policy and priority should be in place when I was running the experiments.
