[Anyone - Please correct me if my terminology or understanding is incorrect]
My limited experience with Real-time programming has been with
RTLinux/RTCore. If I understand correctly, the way to write a real-time
task with RTCore, is that it is written as a kernel module. You have a
small main() which initializes a pthread where you task work is done.
If I do need my rendering to be done in a real time task, is this
something that can be done with OSG? Is that how it's done under
RedHawk? Sorry this is so off topic....
Is there an example which shows how to have a separate thread, from the
main app thread, which does all the OSG stuff?

Hi Ed,
Ive used OSG on RedHawk. In fact, many trips around the sun ago, I
used to be a systems engineer for Concurrent Computer. IITSEC of 2003
I put my hang-glider simulator in Concurrent's booth and drove a
cluster, using the ccur running RedHawk as the master channel. The
role of graphics does not really call for hard-real time, but some of
the other activities associated with the simulator did, including the
frame scheduler and synchronization of the slave channels with the master.
The real-time extensions that CCUR brings to the Linux kernel are the
same ones they've been using since SVR5mp in the early nineties, and
conform to Posix 1003.b and 1003.c real-time standards. The extensions
allow for a fully preemptable kernel with resource allocation and very
good thread priority support.
My experience was quite positive with Red Hawk.

I am working on a project which has as its end goal a hard real-time
system using OSG for the rendering. I have been considering RTLinux
Pro and RedHawk Linux as my RTOS. Anyone have any experience, good or
bad, with OSG on RTLinux or RedHawk? Anyone out that using OSG in
hard real-time?
