We propose a tool-flow methodology that can be applied to analyze and track the performance of OpenCL applications on heterogeneous platforms. Using a case study on a datacenter representative workload, we evaluate our tool flow on three distinct heterogeneous platforms and demonstrate how it can be employed more widely to provide insight and track attainable performance of OpenCL applications. Our methodology is motivated by the need for a common set of metrics that can characterize the performance and power efficiency of OpenCL applications on the increasingly diverse range of emerging heterogeneous platforms now relevant to both HPC and the datacenter market.
