[gmx-users] RE: Gromacs on GPU: GTX or Tesla?

2011-08-07 Thread Efrat Exlrod
Hi Szilard,



Thank you very much for your input.

At the moment we want to buy a single card (GTX-580?) in order to gain 
experience in working with GPUs. In the future we will probably like to have a 
cluster, especially when multiple GPU cards will be supported by Gromacs.



Thanks, Efrat

Hi,

Tesla cards won't give you much benefit when it comes to running the
current Gromacs. Additionally, I can tell you so much that this won't
change in the future either. The only advantage of the C20x0-s is ECC
and double precision - which is ATM anyway not supported in Gromacs on
GPUs.

Gromacs in general doesn't use much memory so unless you will want to
run gigantic systems with a single card, C2070 will not give you any
added benefit at all, in fact 1-1.5GB/card should be more than enough.

What kind of machine are you planning to buy/how many GPUs?

Hi,
In the long term the Tesla is much more preferable as the GTX would not support 
certain high end functions. Pls verify these before you purchase one. Also the 
Tesla C-2070 is the newer one available and with 6.0GB RAM it really gives out 
great performance. The price is the same.

Hi,



We want to start using Gromacs on GPU and we are debating whether to purchase 
GeForce GTX card or Tesla platform. Looking at the published data it seems 
GTX580 has much impressive performance compared to Tesla C2050, and of course 
it is much cheaper. Is there a reason to prefer Tesla over GTX for running 
Gromacs in the short or long term?



Thanks, Efrat
