Distributed Process Scheduling Algorithm

Having got some clarity of what I have to do, I want to now proceed
for a step by step development. What all I know about linux kernels is
a theoretical understanding of its various components (from the book
of Robert Love) but as far as practical is concerned, I know the
following things:
1) Linking modules dynamically to kernel at run time ( outside source
tree and inside source tree)
2) Adding system calls

Rather than trying to go blind folded in getting practical experience
of linux programming, I want to gain experience only in relation to my
task of creating a distributed process scheduler. What all things
should I try to work with to understand the kernel CFS scheduler well?
Please provide sufficient literature for the practical work.
Also what is the best place to learn about implementing linux containers?
