please notice that 32-bit programs can usually only use 2GB of ram. No idea
if this hits VMD here, too, but it might be a possible reason for the

Linux is always better. :D I can't speak to the plans for if/when VMD will
compiled for 64 bit windows, but I do know that 90% of the VMD power users I
know (an admittedly biased pool) use some distribution of linux when running
VMD (the other 10% run Macs). In terms of distro, if you choose to go down
that path, it mostly boils down to personal preference, as the install
procedure and running VMD itself are identical across distributions. If you
are serious, I'd make a few virtual machines first to see which environment
you like first, as different distros use different graphics managers that
may drive you crazy when it comes to day-to-day usability. VirtualBox is a
good program for playing with virtual machines, as its free, making the
total cost to try this out $0. It is also possible to run VMD from inside a
virtual machine. You won't be able to use CUDA, but at least you can get
around the 32-bit size limitations if you install a 64-bit operating system.

I have been trying to load a DCD file (about 3.5 Gb) using VMD but VMD
always crashes when it is loading something like 2-3000 steps. My PC runs
Windows 8.1, i7, 16Gb of memory and a NVIDIA graphics card with 2Gb, so I do
not think it is hardware but software. As it was commented before, it might
be due to VMD being 32 bit (it seems that it does not happen using Linux)
and therefore I will have to try and use the bigdcd script if I continue
using Windows. Because of that, I would like to ask some questions: Is there
any chance that VMD will be compiled for 64 bit in the next future ?. If
not, would it be better to use Linux instead of Windows to work with VMD?.
In this case, is there any Linux distribution which is better suited to work
with VMD or it really does not matter?.
Thanks a lot.
My very best regards,
