1. A method for selective utilization of graphics processing unit (GPU) acceleration of database queries in database management, the method comprising: receiving a database query in a database management system executing in memory of a host computing system; determining a set operations whose performance is required to process the database query; concurrently estimating both a time to complete processing of the determined set of operations requisite to servicing the database query using GPU accelerated computing in a GPU and also a time to complete processing of the determined set operations of the database query using central processor unit (CPU) sequential computing of a CPU; and, routing the set of operations of the database query for processing using GPU accelerated computing based upon both estimates if the concurrently estimated time to complete processing of the set of operations of the database query using GPU accelerated computing is less than the concurrently estimated time to complete processing of the set of operations of the database query using CPU sequential computing, but otherwise routing the set of operations of the database query for processing using CPU sequential computing.
