The State-of-the-Art in Directive-Guided Auto-Tuning for Acceleraotr and Heterogeneous Many-Core Architectures

In this whitepaper we discuss the latest achievements in the field of auto-tuning of applications for accelerator and heterogeneous many-core architectures guided by programming directives. We provide both an academic perspective, presenting preliminary results obtained by the EU FP7 AutoTune project, and an industrial point of view, demonstrated by the commercial uptake by a leader in compiler technology and services, CAPS Entreprise.
