Dear Ross:
I should have better advised that the machine has indeed the X system and even
gnome, though it is used for QM computations, so that it is set to be launched
to give the console prompt. On rare occasions, the X system is called with
"startx" and after that, if needed, gnome is launched with "gnome-session".
When I carried out the compilation of amber9, no X had been called. Should you
need details about the X system on my machine, please ask (no nvidia modules
and no OpenGL installed).
To my excuse, I normally use that parallel machine with graphical output (ssh)
to the Athlon 32 bit single processor computer, where OpenGL is working, and
from where I am writing. In particular I do so with the NWChem/ECCE suite.
Calling X, with its unavoidable 32bit inside, to a 64bit system is slowing
down. I am already at the limit of possibilities for QM calculations with my
large molecules.
I thought urgent replying before examining the Makefile, as suggested by David
on another email. I'll do that. In particular I can't realize the advantage of
graphical xleap. It would be nice to have an arragement of amber9 where xleap
is startd only when X is started. May be installig xleap when X is activated
and then let it doormant when not needed? Is a support like gnome (and openGL)
also needed for xleap? I am already quite unhappy with the 32bit libraries that
I had to install for only the Intel compilers.
Is it possible to replace the service of graphical xleap with VMD? This is
installed on thei Athlon machine, together with a graphical MM package that I
use to build organic molecules and preliminarily minimizing it. It outpots also
pdb and sybyl files.
Thanks to all
