Methods and apparatus are provided, as an aspect of a combined CPU/APD architecture system, for discovering and reporting properties of devices and system topology that are relevant to efficiently scheduling and distributing computational tasks to the various computational resources of a combined CPU/APD architecture system. The combined CPU/APD architecture unifies CPUs and APDs in a flexible computing environment. In some embodiments, the combined CPU/APD architecture capabilities are implemented in a single integrated circuit, elements of which can include one or more CPU cores and one or more APD cores. The combined CPU/APD architecture creates a foundation upon which existing and new programming frameworks, languages, and tools can be constructed.
