any uefi application that can simulator multi processor dispatch logic in OS

any uefi application that can simulator multi processor dispatch logic in OS

[wang xiaofeng]

Hello,
   Do anyone know uefi application that can simulator multi processor dispatch logic in OS ?
   UEFI defines EFI_MP_SERVICES_PROTOCOL, usually bios use this protocol to do BSP and AP initlizaition. StartupAllAPs is called to run the same logic function.
   Any EFI application can divide a task to different thread context and assign to idle AP by random or different dispatching logic?
   Or I need a Mini UEFI OS to do it?
  Thanks in advance!

I believe what you want is a multi-threading capable tiny OS.
I don't know a real project for your purpose.
But I guess there should be plenty of such projects there, just need porting effort.

Thanks/Ray

yes,  small tiny OS that can run on UEFI is OK for me
