[ECOS] smp platform

[ECOS] smp platform

[Hyeonjoong Cho]

Hi all,

It is scary to decide the platform for my project.
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.

 Best
 Cho
