<p>Hi Szilard,</p>
<p> </p>
<p>Thank you very much for your input.</p>
<p>At the moment we want to buy a single card (GTX<a></a>-580?) in order to gain experience in working with GPUs<a></a>. In the future we will probably like to have a cluster, especially when multiple GPU<a></a> cards will be supported by Gromacs<a></a>.</p>
<p> </p>
<p>Thanks, Efrat<a></a></p>
<p> </p>

Hi,<br>
<br>
Tesla cards won't give you much benefit when it comes to running the<br>
current Gromacs<a></a>. Additionally, I can tell you so much that this won't<br>
change in the future either. The only advantage of the C20x0<a></a>-s is ECC<a></a><br>
and double precision - which is ATM anyway not supported in Gromacs<a></a> on<br>
GPUs<a></a>.<br>
<br>
Gromacs<a></a> in general doesn't use much memory so unless you will want to<br>
run gigantic systems with a single card, C2070<a></a> will not give you any<br>
added benefit at all, in fact 1-1.5GB<a></a>/card should be more than enough.<br>
<br>
What kind of machine are you planning to buy/how many GPUs<a></a>?<br>
<br>
