Michael, play around with the hash_max value, which seem to partially control
how much memory is used during rendering. You can also reduce the quality of
the rendering Display->Quality, that should reduce memory requirements too. I
know you don't want that, but do you really need max quality? Finally on Unix
or even Windoze you can look at how much memory is consumed during rendering
using top (on Unix) and the task manager on windows. That should give you some
clue if you are really exceeding the physical memory or not. Finally you could
split the rendering into smaller pieces, export to Povray, combine the files
under a common header and render there, alternatively try if the "Draw" command
gives you what you want, albeit not quite as fancy as the raytracer.

Subject: [PyMOL] PyMOL crashes under Vista Home Premium & Ubuntu 8.04
LTS
Hi,
I have a problem when trying to ray 750,750 a quite large ribosome file
with maximum quality. Size of the relevant PyMOL v1.1 file is 100 MB (or
31 MB after reducing objects I do not need for the figure production).
PyMOL simply crashes under Windows Vista Home Premium as well as under
Ubuntu Linux v8.04 LTS without error report. My dual OS system is a
Samsung Aura Seven Notebook (Core2Duo @2.4 GHz each, 3 GB of RAM, NVIDIA
GeForce 9200M GS graphics board with 256 MB of RAM, 12" TFT @1280x800
resolution settings). I first thought the RAM under Vista is still
insufficient (Vista alone takes 900 MB of the 3 GB of memory) but then
I realized that this crash occurs as well under Linux. However, since
both OS are 32 bit and therefore to my (limited) knowledge cannot handle
more than 2 GB in a single task, RAM limitation might still be an issue
to think about, right?
I have experienced (and occasionally reported) this type of serious
crashes with PyMOL on a broad variety of machines over some years now -
usually occurring when trying to render final files - but, sadly, none
of these has ever been diagnosed and fixed properly. Maybe this time I
am lucky and someone knows what to do?
Best regards,
Michael.
