Data Management for Molecule Simulation : A Throughput-Oriented Approach - Project Summary We will design and develop a molecular simulation data management system, we call P2DMS, to analyze large dis- tributed molecular dynamics (MD) simulation data. The salient features of the system include: (1) a push-based local query engine design that handles data in a batch processing manner and processes many queries at the same time; (2) optimized MD analytics tools using modern many-core hardware such as GPUs; and (3) efficient management and access to distributed data over wide area networks, which is quite common for large scale MD simulations. This will be done by building a data analysis layer on top of state-of-the-art distributed big data management systems. The out- come of this project will not only improve the efficiency of MD data processing, but also enable new knowledge discov- ery that is currently regarded difficult or infeasible. In particular, we will integrate the P2DMS program into existing MD simulation packages, and validate the new design with important real-world biological and MD methodological prob- lems. In particular, we will (1) model the structure-function relationships of how the spike protein of SARS-CoV-2 inter- acts with the human angiotensin converting enzyme 2 (ACE2) receptor; and (2) enhance the performance of a recently developed parameter optimization software for active control of MD simulations.
