Abstract
Abstract. 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. 1
