The San Diego Supercomputer Center has just installed X11R2 on it's Cray
X-MP/48 computer system.  At USC I have a color Sun-III/160 running the
X11R3 maintained by the campus computer center.  I seem to be having a
few small problems getting clients on the cray to communicate with the
server on my sun.  So I was hoping someone in the comp.windows.x community
might be able to answer a few questions:

o  Are there any inherent incompatibilities between X11R2 clients and
   X11R3 servers?  If so, what kind of problems will I encounter?  Do
   you have any software or operating procedure suggestions to solve
   these problems?

o  Does anyone else have experience running X11 in this configuration?

o  Where could I get a copy of the sources for X11R2 if I need to use it?

o  Does anyone know when a Cray based X11R3 will become available?

o  If I obtain an official MIT distribution kit for X11R3 via anonymous
   ftp over the INTERNET, where can I get a full set of prior maintenance
   patches and where can I continue to obtain future maintenance patches?

o  Does anyone maintain (is it possible to maintain) either sources or
   compiled object code or linked executable code in a fully up-to-date
   version that could be copied and installed on my sun whenever update
   is required?  This would benefit people who need to get on with their
   research in some area other than computer science but want to use the
   most current tools to accomplish their research.

o  What are the Purdue speedups?  Where does one obtain prior and current
   copies of these patches?  Are up-to-date source, compiled, or linked code 
   availanle for anonymous ftp?  Once again, this would reduce the amount
   of time non computer scientists would need to spend doing software work.

o  Does anyone have image processing and/or signal processing packages
   available for X windows on the Sun?  Are these packages sufficiently
   portable to be moved to the SDSC Cray?

Thanks, AJ Annala
