[gmx-users] mixed single-precision GPU and double-precision CPU calculation

[Makoto Yoneya]

Dear GROMACS peoples:

I know the current gromacs-4.6 can't build with both GPU and double
precision being enable.
I'm wondering is it possible to modify mixed single-precision
(non-bonded) GPU calculation and double-precision CPU calculation?
I suppose this combination would be practically useful when we needs high
precision constraint 
calculation (with SHAKE or LINCS etc.).
If it is possible by modifying some routine, please teach me the routine to
modify.
I would like to try it.

Thank you for advance.
