Running Xhpc on E-100 generates a "Segmentation fault (core dumped)" error,
and dumps a 2.5 MByte Xhpc.core file in the current diretory.

I also suspect that Xhpc should be configured somehow... but I lack of
documentation. Where, what, and how to configure? (fe there is directory
/usr/X11R6/lib/X11/config which is empty. Supposed it to be?) Is there some
kind of prg like xf86config ? Or has Xhpc some similar config files like
XFree86?

I aslo tryed:
setenv DISPLAY localhost:0.0

my Cassiopeia has 16 Megs of RAM, and it has a 2Mbyte swap file.
