METHODS AND APPARATUS TO IMPROVE RUNTIME PERFORMANCE OF SOFTWARE EXECUTING ON A HETEROGENEOUS SYSTEM

摘要

Methods, apparatus, systems and articles of manufacture are disclosed improve runtime performance of software executing on a heterogeneous system. An example apparatus includes a feedback interface to collect a performance characteristic of the heterogeneous system associated with a compiled version of a block of code at a first runtime, the compiled version executed according to a function designating successful execution of the compiled version on the heterogeneous system, the heterogeneous system including a first processing element and a second processing element different than the first processing element; a performance analyzer to determine a performance delta based on the performance characteristic and the function; and a machine learning modeler to, prior to a second runtime, adjust a cost model of the first processing element based on the performance delta, the adjusted cost model to cause a reduction in the performance delta to improve runtime performance of the heterogeneous system.
