Hi, Is this rather large box a system that can actually be simulated with a useful speed on a single Fermi GPU? Even with 5 fs time-step you won't get much more than 1-1.5 ns/day on a fast Fermi GPU like a GTX 580. Given that you are quite a bit above the limit, unless you are using a quite

I've run into a problem with an older card (GTX-580) which is CC 2.0. On a larger box size, mdrun stops with: Fatal error: Watch out, the input system is too large to simulate! The number of nonbonded work units (=number of super-clusters) exceeds themaximum grid size in x dimension
