OK guys, thanks for all your replies.
What I have is the following.
I'm building a hard real-time Linux (RTLinux) system on a 2x Xeon machine. If I compile and run a 2.4.18 kernel with SMP support, rtlinux hangs the machine. However, with SMP disabled, rtlinux and all it's hard-realtime applications runs okay.
So, I have to deside between these two:
- Run rtlinux and hard-realtime applications on a kernel without SMP support. How much performance will I loose this way? Is SMP *THAT* critical?
- Run all tasks in a usual way, no hard realtime, but with SMP support.
What would you suggest?
Also, if I turn hyperthreading off, how will it influence the system with SMP support? Without SMP support?
Thanks!
