RE: Simulation Server

Aaran-
 
I am not sure which processor is best, but faster is always better. Linux
is a good choice of OS. We recently compared some run times for our
recently released Eugene, OR tutorial model and Linux consistently ran
faster than Windows, often by a large margin. The more RAM you have the
better, I think 2GB would be a minimum recommendation depending on the size
of your database. I think our servers run the PSRC model with 4GB of RAM.
My guess is that the disk speed is of least concern, I dont think that there
is lots of disk activity unless you dont have enough RAM. Perhaps one of
our developers will have more to say about this.....

Hi,
 
We are about to purchase a server dedicated to running UrbanSim 4.  I just
thought I would ask if anyone had any advice on what sort of a system I
should be looking for.  Namely should I invest in faster disk, cpu or ram.
Obviously all 3 would be nice but I do have a budget to stick to.  I was
thinking the 64 bit Opteron Chips running Linux was a good idea for pure
number crunching capability?  Any suggestions or tips are most welcome.
 
Regards,
