Ah, I spoke with Gianluca a few years ago about ACS and I lurk on the
ACS mailing list.
We have had success here and at Magdelena Ridge Observatory with our
framework using plain ACE/TAO on Linux, but then using the Xenomai RTOS
to schedule RT threads. So we do not compile TAO against Xenomai, but
have some ACE threads which are promoted to RT threads with explicit
calls to Xenomai. I'm not sure what rates are used in ACS (I know some
of the target systems are lower rate things like telescope controllers),
but we get threads firing at rates up to 5kHz for our interferometer
If you want more details feel free to ask.
