Hi, I am looking for a workstation for molecular dynamic simulation work using gromacs (http://www.gromacs.org/) but I am not an expert in building computer, what would you guy recommend for this kind of work? no budget constrains

we can go as high as you can go (30k$+)

so please give us a budget

around 8.5k$,

also you can give the ultimate machine with no budget constrain is case got grants from somewhere

FYI; I heard gromacs optimised for CUDA and work better with single socket cpu board

something like this guy is building maby?: 

 

I spent $2500 on building my PC and all i do with it is play no games atm & watch anime at 1080p(finally) watch YT and write essays...  nothing, it just sits there collecting dust...

Builds:

The Toaster Project! Northern Bee!

 

The original LAN PC build log! (Old, dead and replaced by The Toaster Project & 5.0)

"Here is some advice that might have gotten lost somewhere along the way in your life. 

 

#1. Treat others as you would like to be treated.

#2. It's best to keep your mouth shut; and appear to be stupid, rather than open it and remove all doubt.

#3. There is nothing "wrong" with being wrong. Learning from a mistake can be more valuable than not making one in the first place.

 

Follow these simple rules in life, and I promise you, things magically get easier. " - MageTank 31-10-2016

I think it should be a single good cpu with a bunch of graphic cards I need GPU power the most and it have to run for a long time(like a week or month) in 100% utilisation for a single simulation, so heat management is another serious issue

Took some inspiration from this site: http://exxactcorp.com/index.php/solution/solu_detail/121

 

Also, extra cores seem to help.
