Your best bet is probably to look at some of the smptests and follow
the logic there. The primary documentation for the kernel is in
doxygen currently:
https://docs.rtems.org/doxygen/cpukit/html/modules.html

You should start to break-down the larger project into smaller
sub-projects/tasks and think about your project plan. This will help
you to write a strong proposal that could guide you through the entire
summer.

Also, getting one of the SMP-capable targets running is a good idea.
Last I remember there is an ARM target you can run in SMP mode on
Qemu.
