Hi, my name is Kevin and i'm from argentina, my english isn´t good, sorry.
I need some information for a work of QNX Neutrino. I will be grateful for them very 

much if they could help me with some information or answering me any of my questions.

 •	Scheduling: details of sheduling (if only use fifo, round robin and sporadic 

this is a general SO... no a RTOS).
•	How handle the multiprocessing?
•	Memory. What is for processor Intel the GDT y LDT=
•	Threads in QNX Neutrnio
•	In what platforms does it work?.
•	How does solve the degradation of the performance for the fact of implementing 

MicroKernel, being that is a system of real time?
•	In what important places there is in use QNX Neutrino?
•	Support & Services, users support
•	Memory Requeriments

Thanks!

--------------------------------------------

•	Scheduling: como funciona, ya que si se utiliza simplemente fifo, sporadic o 

round robin es un sistema general, y no uno de tiempo real.
•	Como maneja el multiprocesamiento?
•	Administración de Memoria: que quiere decir que para procesadores Intel haga uso 

de GDT y LDT?
•	Manejo de hilos
•	Plataformas aptas.
•	¿Cómo resuelve la degradación de la performance por el hecho de implementar 

Micro Kernel, siendo que es un sist. de tiempo real?
•	Mercado: usos en sistemas reales
•	Soporte a usuarios: Support & Services
•	 Requerimientos de Memoria
