Sun as Front End for CRAY running Unix

[Krishnan K. Chittur]

I am trying to find information about software that will allow the use of
a Sun as a front end for the CRAY.  i.e. as a graphical front end for the
Cray.  Calculations will be done on the CRAY and the display will be on
the SUN.  I am aware of NCST (Urbana) and some of the other super computer
sites that have in the past posted some of the software that I am
referring to.  

Can some one please direct me to an appropriate site from where I can ftp?
I need software for both 2d and 3d displays.  I will also appreciate any
useful tips about doing this.
