I want to port eCos to SMP machine with about 4 CPUs. Is there anybody who is working on it? If so, would you recommend off-the-shelf machines, which proved stable with eCos? Is there any report on porting eCos on SMP machine? Another thing I want to ask is the overload situation on CPU, e.g. where the toal execution times of all tasks(demand) exceed the CPU capacity(supply). To deal with it, the key is that OS should be able to handle tasks with their job ID, not with their task ID.( The job is an instance of a task). For example, SHaRK( a hard real-time OS) hanlde tasks with their task ID not with their job ID, so that it cannot deal with the overload, where two jobs from a single task should have different ID. Please help me pick up a right platform. Thank you so much.
