Thank you all for the reply, now I'm much less confuse and thank you David for the paper. I wanted to try implicit simulations because I need to speed up a bit my simulations...but I think that now I'll try something else (coarse grained/remd). cheers Fra On Mon, 23 Sep 2013, at 08:28 PM, David

[gmx-users] confusion about implicint solvent

2013-09-23 Thread Francesco
Good afternoon everybody, I'm a bit confuse about gromacs performances with implicit solvent. I'm simulating a 1000 residues protein with explicit solvent, using both a cpu and a gpu cluster. With a gpu node (12 cores and 3 M2090 gpu ) I reach 10 ns/day, while with no gpu and 144 cores I got 34 ns
