Here are quick answers with some explanation:
ABF, meta-dynamics - yes (doesn't alter nonbonded interactions)
useFlexibleCell, useConstantRatio, useConstantArea
- yes since NAMD 2.7 (pressure tensor is now calculated on GPU)
accelerated MD - no (requires energy, which is not accelerated) but
should work when energy evaluation on the GPU is implemented
Martini force field - martiniSwitching is broken in both CPU and GPU,
but yes when the bug is fixed, but coarse grained systems won't
see much of a performance boost from the GPU because there just
aren't that many particles. You could benchmark it as-is, though.
implicit solvent - no (requires special nonbonded interactions) but
certainly a candidate for the GPU in a future release
