-
- CHORUS is NOT an OS based on Mach !
- CHORUS is a real-time microkernel written by Chorus Systemes (Paris).
- It has the same features than Mach.
-
- Chorus/Mix is the Unix Multi-server running on top of the micro-kernel. There are
- different versions of the server (BSD, SYS VR4).
-
- At CERN, a group is porting Chorus and Chorus/Mix to the T800 and T9000
- transputers (Harmony project).
- Chorus is used in a distributed operating system course made at the university
- of NANCY (France) by Francois Schwaab (schwaab@loria.fr). I'm in fact a student coming from this university.
- It is used in the industry too : Alcatel Business System (Strasbourg, France)
- use the Chorus microkernel in its telecommunication products.
-
- Chorus has a few interresting features not present in mach (real-time,
- supervisor actors) but many theorical features are not yet implemented
- (Kernel 3.3 lacks port migration, remote actors and threads creation,
- region migration, etc...)
-
- Does anybody know if the Chorus microkernel 3.4 has all these interresting features ?
- Is there a chorus newsgroup ?
- Does anybody use Chorus (any types of machines) (industry, research, university)?
-
- Please reply by email.
