> I am wondering does anybody have experience with GROMACS for large scale simulation? I've heard lot of people said that it would be difficult for Gromacs to do so. eg: I've got a 60,000 atoms system, is it possible for GROMACS to produce 100 ns/days or even more? suppose I can use as much CPU as possible.... My recent experience for such system, Gromacs can only produce up to 20ns/day.... If I would like to produce 1000 ns, I have to wait for 50 days......
We are about to publish a paper where have 1,2 million atoms and get 30 ns/day. On 2000 cores.
