[fm514@wanadoo.fr (Franck Martin)]

We’ve no experience in real-time software (just the student
level).
So,as we need to start, we choose a free software :hurd.
It will be nice if you’ll be agree to answer our questions.


Here are our interrogations :

-	Which platforms are allowed with Hurd ? 
-	Could you give us some cross referencer name for development ?do any
debugging tools existing ?
-	Which kind of communication between task are possible ? (mail box ?,
shared memory ?, sockets ?)
and how do they work ?

-	How do hurd manage the task memory allocation ?(pagination ?,
dynamic allocation ?)
-	How many tasks can run in the same time ?
-	What is the time switch between tasks ?
-	How the task overflow is manage by hurd ?
-	How context memory is manage ?
-	About the scheduler : Could you explain us how the scheduler is
working ?(time quantum,
-	dynamic priority).
-	In comparaison with VXWorks and PSOS+, what does hurd offer more ?
-	What are the mains problems with hurd ?(deadlocks).
-	Today, which industrials sectors use Hurd (for which applications) ?
-	Could you give us a basic example of a Hurd program ?
-	What is your feeling about Hurd ?


We’ve already surf on the web and read GNU sites, but its
contains very generals informations.
