  Traditional monolithic kernels dominated kernel structures for long time
along with small sized kernels,few hardware companies and limited kernel
functionalities. Monolithic kernel structure was not applicable when the number
of hardware companies increased and kernel services consumed by different users
for many purposes. One of the biggest disadvantages of the monolithic kernels
is the inflexibility due to the need to include all the available modules in
kernel compilation causing high time consuming. Lately, new kernel structure
was introduced through multicore operating systems. Unfortunately, many
multicore operating systems such as barrelfish and FOS are experimental. This
paper aims to simulate the performance of multicore hybrid kernels through
dynamic kernel module customized attachment/ deattachment for multicore
machines. In addition, this paper proposes a new technique for loading dynamic
kernel modules based on the user needs and machine capabilities.
