OP2 is an "active" library framework for the solution of unstructured mesh applications. It aims to decouple the scientific specification of an application from its parallel implementation to achieve code longevity and near-optimal performance by re-targeting the back-end to different multi-core/many-core hardware. This paper presents the design of the OP2 code generation and compiler framework which, given an application written using the OP2 API, generates efficient code for state-of-the-art hardware (e.g. GPUs and multi-core CPUs). Through a representative unstructured mesh application we demonstrate the capabilities of the compiler framework to utilize the same OP2 hardware specific run-time support functionalities. Performance results show that the impact due to this sharing of basic functionalities is negligible.
