I have heard rumors that the Cray at SDSC supports some version of X11. Is this true? If so has anyone attempted to run clients on it to drive their local X machines? As I understand it, this computer is used by many universities outside of CA, hence the usa distribution.

Cray Research supports X windows under Unicos (Cray unix).
With Unicos 5.0 (released last month) X11R3 is supported.
At the Minnesota Supercomputer Center we take advantage of
X windows to support graphics directly from our Cray 2. The NCSA
at Illinois has also jumped on the X bandwagon. It is very handy
to interactively pop up some raster or plots from the Cray, as opposed
to first transferring data to a workstation.

However, the SDSC Cray X-MP/48 is running CTSS not UNICOS. As a consequence, I have encountered a few small problems porting X11 clients to the current SDSC Cray configuration. As one example, it would appear that communication protocol restrictions preclude the building a new 256 pseudocolormap in one call. You have to split up the call into several smaller partial pseudocolormap transfers. Better support will be available when SDSC finishes testing UNICOS and releases it for general use late this year/early next year. Until that time, applications developed from scratch on the cray will probably run ok. But attempts to port applications from other environments may be expected to encounter many small problems. p.s. The protocol employed by the X11R3 (SUN) server appears to be completely compatible with the X11R2 (Cray) library.
