1. An article of manufacture comprising a non-transitory computer-readable storage medium containing instructions that, when executed, enable a system to: generate simulated data for a statistical test, statistics of the statistical test based on parameter vectors to follow a probability distribution; simulate statistics for the parameter vectors from the simulated data with a distributed computing system comprising multiple nodes each having one or more processors capable of executing multiple threads, the simulation to occur by distribution of portions of the simulated data across the multiple nodes of the distributed computing system; and control task execution on the distributed portions of the simulated data on each node of the distributed computing system with a virtual software class arranged to coordinate task and sub-task operations across the nodes of the distributed computing system.
