New comment by momeara in "‘Virtual Pharmacology’ Advance Tackles Universe of Unknown Drugs"

Hey Chris--We're right now using a mix of commercial and open source software like Omega, Corina, AMSOL, and Mol2DB. Probably the slowest step is generating the partial charges for each conformer with a reasonably high quality semi-empirical forcefield. I'm not sure if there are competitive (in terms of quality) GPU based methods, but if there were methods that were ~1000 times faster as can be the case for GPU based methods, it would definitely speed up the pre-computation or make on-the-fly prep feasible. Do you have any ideas of where we should look?

Co-author here (AMA)--A large-scale docking screen of 116M molecules takes ~1100 cpu days on our cluster, working out to about 1 mol/sec, which is very fast for virtual screening. What this doesn't account for is this requires about 30 minutes per compound to precompute information (conformations, partial charges, etc.). So this works out to ~6M cpu/hours to prepare the library for screening, which is a substantial amount of computation. We're loading about 1M molecules a day and have a 2-3 year backlog of compounds to load from Enamine.

The good news is that once the library is prepared, it is quick to screen at more targets--and we make the pre-computed library available at zinc15.docking.org.

Interestingly, as the library grows a limiting factor is storing the library on disk. It is now ~20T. We've set up several mirrors around the world for groups that are actively using it. An interesting problem will be to see if preparing compounds for screening on the fly (e.g. with machine learning models) can overcome this limitation to keep up with library growth.

A big question for us is what will the return on investment in screening larger and larger libraries be? One of the take aways from this work is if docking has moderate enrichment, than screening larger libraries not only gives more hits but actually can increase the hit-rate for the top scoring compounds.
