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 ...

Till Straumann's CEXP package provides features similar to those of
the vxWorks shell. You can call arbitrary functions, print or set
variables by name, etc.

OAR presents RTEMS training courses in Europe approximately once a
year. I'm sure that they'd be happy to take on contract work for
custom driver development, too.
