For the rest of us mere mortals who don't have access to specialized hardware

are probably more feasible. Unbiased simulations of sufficient length, using
"standard" supercomputing hardware, would probably take years.

Do you think implicit water with 10-20 ligands would be able to do it?
I see that the gpu accelerated implicit gets about 100-150 ns/day so a
10-20 day simulation would yield that time frame, no?
Thanks :)
In an implicit, non-periodic system, it is more likely that the ligand will
float away from the protein. I've tried it and that's all that ever happens.
Moreover, the current Gromacs version does not support implicit solvent on GPU
and the previous version that did had very limited functionality.
