[gmx-users] mdrun_d and grompp_d

[Choon Peng]

Hi Tanos,

  You simply have to recompile your FFTw and Gromacs with the option
"--disable-float" and new grompp/mdrun will be greated with suffix _d to
indicate that they are for double precision calculations.
Do a "make distclean" before recompilation/installation.
However, there's a speed penalty with the increased precision.

But today I realized that my version of GROMACS doesn't have this program. So I'd like to know how to proceed to download this options to my machine.
