Yes... with a reasonable computer (cpu strength), Gromacs code is the best of the three. Fewer points, per workunit, but a pentium IV can crank out a completed workunit, every 12-36 hours, depending on how you use the PC.
Eventually, FAH will move to nothing but Gromacs, but there are a lot of Tinkers and Ambers that still have to be processed, before they can close those projects down.
You won't score near as many points with a Gromacs, but you'll click them out, at a steady pace, which, depending on your CPU, puts you ahead of the game.
Nothing, is agony, like watching a G3/G4 mac, or an old PIII get ahold of a Tinker.... It's worse than pulling teeth.
I had a tinker last week. I was getting 7 mins, 40 secs a frame.
This Gromacs code is 36 secs a frame.
I didn't know that. I guess, the sooner we get through all those Tinkers, the better for everyone :)
