[gmx-users] Vacuum simulation in GMX 5

[Eudes Fileti]

Hello,
in the previous gmx versions I could accelerate simulations in vacuum
making the cutting cut-offs zero and pbc = no.

However, now it is no longer current possible with GMX 5 (since pbc = no is
not supported with dd, and the particle decomposition mode is not suported
in GMX 5).

Does anyone have any tips to speed up a calculation in vacuum?
I'm decoupling a small molecule in vacuum (for an free energy calculation)
at a rate of 1ns/h, which seems very slow.
