Hi,
I am currently trying to decide what QMD program(s) to advocate for our modeling
group and am looking for a review(s) of the current state-of-the-art in terms
of:
1) Theory (what methodologies are in use, best practices, frontiers, areas of
agreement/disagreement);
2) Programs (speed, scaling behavior in CPUs/GPUs, ease of use, analysis
abilities, cost...);
3) Simulations (practical limits in box size, atoms number, element types,
addition of constraints/pathways...)
Most of what I have found is either too specific or biased.
By the way, what I mean by QMD is Born-Oppenheimer dynamics (classical nuclei
with QM electrons), either CP or PAW based. I am leaning toward Abinit (scales
well, free) or VASP (fast, not free), but am pretty open to other suggestions.
I am a traditional quantum chemist by training and have a lot of classical
protein simulation experience as well, but not very knowledgable about plane
wave simulations. I really want to find out what folks are using now and the
computational cost in CPU hrs. for systems as a function of box size and
simulation length.
Thanks,
Bill
