abstract = {Committor analysis is a powerful, but computationally
expensive, tool to study reaction mechanisms in complex
systems. The committor can also be used to generate initial
trajectories for transition path sampling, a less-expensive
technique to study reaction mechanisms. The main goal of the
project was to facilitate an implementation of committor
analysis in the software application OpenPathSampling
(http://openpathsampling.org/) that is performance portable
across a range of HPC hardware and hosting sites. We do this
by the use of hardware-enabled MD engines in
OpenPathSampling coupled with a custom library extension to
the data analytics framework Dask (https://dask.org/) that
allows for the execution of MPI-enabled tasks in a steerable
High Throughput Computing workflow. The software developed
here is being used to generate initial trajectories to study
a conformational change in the main protease of the
SARS-CoV-2 virus, which causes COVID-19. This conformational
change may regulate the accessibility of the active site of
the main protease, and a better understanding of its
mechanism could aid drug design.},
