NSLS II at Brookhaven expects to use RTEMS. We are just starting - so
you are further along than us. LCLS is using it and Till and Ernest
should comment on that. Eric should say to what extent it is deployed
at APS. And Elder should talk about their experience at CLS - I think
that they have the longest history there - when Eric did the port of
EPICS.

Subject: RTMES vs VxWorks
Hello All,
We are in the design phase of a new accelerator project which will be
built in the frame of the so-called "broader approach of the ITER
project". The goal of this accelerator (Eveda) is the validation of
the solutions for the future high power accelerator IFMIF
(International Fusion Materials Irradiation Facility).
The control system will be based (of course) on Epics with VME IOCs.
The question is which RT OS to use? We are users of VxWorks for a
very long time for several projects and we were always very happy
with this system. It's expensive and we are no more privileged
customers of VxWorks but it's for sure a great product. As we saw
some interest for RTEMS in the community, we did complete tests with
Epics including the port of drivers for our favourite modules. All
this was satisfactory, so we are really now at a cornerstone... and
we need some feedback of facilities using RTEMS. What are the
advantages or drawbacks based on your experience? Reliability?
Off-the-shelf availability of drivers (for PMC modules for example)?
availability of great features of VxWorks like the global symbol
table or the interactive functions call? Etc ...
Many thanks,
Jean-François
