The initial wave of programming models for general-purpose computing on GPUs, led by CUDA and OpenCL, has provided experts with low-level constructs to obtain significant performance and energy improvements on GPUs. However, these programming models are characterized by a challenging learning curve for non-experts due to their complex and low-level APIs. Looking to the future, improving the accessibility of GPUs and accelerators for mainstream software developers is crucial to bringing the benefits of these heterogeneous architectures to a broader set of application domains. A key challenge in doing so is that mainstream developers are accustomed to working with high-level managed languages, such as Java, rather than lower-level native languages such as C, CUDA, and OpenCL.
