Re: non-preemptive Linux version?

Hi,

Does anyone know how to make an application fully control its CPU
timing? E.g.,
if the program is doing intensive computation, it should not be
context-switched
by the kernel and other users' processes. Is there any option in the
kernel
to enable it, or I can download some special version of Linux to do it?

It is widely used in the compute nodes of clusters.
Any suggestion and help would be greatly appreciated!

PS: disabling preemption in the kernel seems not working.

Thanks,

Why not look at the scheduler code and see?

And rewrite it if necessary...

Why not just up the nice value?
