First, please spell out your words...it's "you", not "U".

You have a better chance of getting answers, when you provide some useful information. You say "our custom made scheduler"...but don't say anything about it, how it works, or what version/distro of Linux you're using. How can anyone answer any questions?

The kernel has little or nothing to do with schedulers...a scheduler just runs a job, no matter if you're using CRON or not.

I am using slackware 12.1 which uses kernel version 2.6 i suppose.
Custom made scheduler means a scheduler which i have written as a mini-project.
After booting,the first process booted is scheduler,so how to make our scheduler boot instead of the currently used schedluer?what changes are to be made and how?

Yeah, I think chaitukanna should start posting questions as if we had no clue about what is in your mind ... because we don't. 'scheduler' in this case can mean a hell of a lot of things, please be more specific. I mean think about it, probably most of this thread will be spend trying to figure out what you are asking, then the second or third page will finally begin to address a solution to the problem. Do try a little harder. Do you mean I/O scheduler or cron or what ?

Are you referring to the process scheduler in the kernel. If that is the case, you should have rewritten the source code for the scheduler in the kernel source. There isn't a scheduler program that is loaded by init when you boot. It is at the center of the kernel and not a loadable module AFAIK.
