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; estimating a time to complete processing of operations requisite to servicing the database query using GPU accelerated computing in a GPU and also a time to complete processing of the operations of the database query using central processor unit (CPU) sequential computing of a CPU; and, routing the operations of the database query for processing using GPU accelerated computing if the estimated time to complete processing of the operations of the database query using GPU accelerated computing is less than an estimated time to complete processing of the operations of the database query using CPU sequential computing, but otherwise routing the operations of the database query for processing using CPU sequential computing.
