The version used by Alan Mark has never made it into gromacs.
Rather, Erik Lindahl started the implementation of this stuff but
did never finish it completely, due to other priorities I presume.
We should however take out the variables to avoid confusion (unless
someone provides a full implementation).
Actually, technically the GB implementation is already in Gromacs
(even assembly kernels), and quite correct, it's just that you don't
have the born radii yet :-)
The last couple of years we've mainly done membrane stuff where it's
not useful for my students, and thus not a priority to implement.
However, recently Per Larsson has finished C implementations of the
Still radius calculations that I've started optimizing.
The big remaining task is the SA part of GB/SA, i.e. the surface
calculation, which also needs to be optimized and preferrably
parallelized (harder) to be useful.
Fan Hao actually offered us the code he wrote with Alan, but the
challengefor us isn't to write a trivial Still GB implementation, but
to make it perform well. There's little point in having a GB
implementation that is slower than the fast explicit-solvent
simulations in Gromacs!
Cheers,
Erik
