The invention discloses a cross-cloud cross-region large-scale
virtual screening method and
system and a storage medium, large-scale
small molecule libraries are classified in a unified
database according to a certain rule, all
cloud computing servers search for uncomputed categories from the unified
database, and the categories are downloaded and marked as computing states at the same time; and the
cloud computing server writes a screening and docking result into the local computing node in the screening and docking process. After calculation of one category is completed, the calculation
server node repeats the above operations until all categories in the
database are identified as calculation states. And each computing
server writes the numbers of a plurality of micromolecules with the highest
score back to a unified database after finishing screening of the downloaded category micromolecules. According to the scheme, the technical problems that according to an existing large-scale
virtual screening scheme on the cloud, cross-cloud and cross-region screening cannot be achieved, screening can only be conducted in a single region of a single cloud, implementation is difficult, and popularization is not convenient are solved.
