METHOD AND SYSTEM FOR IMPROVING SOFTWARE EXECUTION TIME BY OPTIMIZING A PERFORMANCE MODEL

摘要

A performance or reliability model representing the behaviour of an application under different system resource conditions is provided. This model may take the form of one or more sparse matrix providing a reliability or performance values for different combinations of conditions. This model is distributed to a user of the application, and is consulted during execution of the application with reference to system resource information provided by the operating system or other monitoring software so as to provide an indication of the expected performance of the application under present operating conditions. This indication may be notified to a user, for example in a case where the indication falls outside predetermined bounds of satisfactory operation. The system may also attempt to renegotiate attributed system resources to as to improve performance.
