Hi All,

Do research groups distribute Cactus/EinsteinToolkit files amongst 
different users on the same machine? I understand that the Cactus 
philosophy is that it is meant to be distributed. But it seems redundant 
for every member of a group, using the same machine, to have their own 
copies of everything. I am curious how other groups handle this. What 
parts of the toolkit are shared amongst multiple users, if any? What 
parts are not shared?

For context, our group is very small (currently myself and a couple of 
grad students). The disk quota for the group on our HPC machine is 
150GB. Right now that is not prohibitively small. I'm more concerned 
about sprawling config files, parfiles, etc. Although if there are 
things that can be done to reduce the overall disk usage, that would be 
an added bonus. So I am wondering what practices other groups employ.
