Abstract: In a method of molecular scaffold hopping an interface of a scheduler computer sends instructions, prepared by the scheduler computer, to a job runner computer to perform a plurality of separate computational tasks. Each of the separate computational tasks includes calculating one or more chemical properties for a query molecule or molecules in a library of molecules. One or more of the plurality of separate computational tasks performed on the job runner computer are preemptible computing instances. Status indicators sent from the job runner computer are received by the interface for each of the plurality of separate computational tasks. The indicators are one of: incomplete, completed, or failed computing instances. The interface resends the instructions to the job runner computer that correspond to the separate computational tasks having the failed computing instance indicator to increase fault-tolerance against the separate computational tasks not attaining the completed computing instance indicator.

Abstract: Evaluating an effect of one or more perturbations on cells of a first cell type is described. One method includes obtaining a screen definition for a screen, where the screen includes a cell-based assay that is run on a temporarily contiguous basis using a plurality of multi-well plates. The method includes obtaining control vectors including measurements of corresponding features of cells in control wells. The method includes obtaining test vectors including measurements of corresponding features of cells in test wells. The method includes forming a variability model based on a variance across the of control vectors, and embedding test vectors onto the variability model, thereby obtaining a set of variability model values. The method includes using the set of variability model values to resolve an effect of at least one data perturbation in the plurality of data perturbations on the first cell type.
