Nowadays we are involing a project named cluster_on_board, on which there are 4~16 cpus on a board, these cpus can be the same and also can be different, and all cpus can see all the memory. We are trying let each cpu running one instance of kernel image(same or different), and communicate through tcp/ip on a virtual Ethernet. Of course, modifications are needed. I think you can do it in the same way. Or any more exciting ideas? 2006/5/12, Krishna Chaitanya : > Hi All! > > I am working on a project where the hardware is Asymmetric Multi > Processing Systems(ASMP). > > In my system I have one ARM9, four ARM7s'. > > 1.
