multiprocessor architecture

[Francesco Poletti]

Hy, I'm developing a multi alrm simulator which one day... will be boot
with rtems.
When I read the shared memory code I saw that may be important for the
comunication between processor which one node will able to interrupt
another node. In my simulator this thing isn't implemented and I'm
asking which way may be more coorect...I'm looking for documentation but
I don't find anything interesting.
Thanks to anyone which can help me.
Francesco.
