“…3 shows the modified EPN topology when the second process is replicated by four. It is worthwhile to mention that the modification of the graph topology is automated in the DAL [6] framework, and thus requires no modification of the user-specified code. In DAL, each vertex in KPN/EPN is synthesized as a POSIX thread, and inter-process communication is enabled by UNIX pipes.…”

“…In order to address this issue, multimedia applications are often described in a formal model-of-computation (MoC). Distributed Application Layer (DAL) [6] is a programming framework based on Kahn Process Network (KPN) [7] MoC, which is capable of offering predictability when realized on multi-core systems [8]. In this paper, we take the KPN implementation of ray-tracing in DAL from [9] and study how to optimize the workload distribution and mapping decision tailored to a given heterogeneous multi-core platform.…”

As more mobile devices are equipped with multi-core CPUs and are required to execute many compute-intensive multimedia applications, it is important to optimize the systems, considering the underlying parallel hardware architecture. In this paper, we implement and optimize ray-tracing application tailored to a given mobile computing platform with multiple heterogeneous processing elements. In this paper, a lightweight ray-tracing application is specified and implemented in Kahn process network (KPN) model-of-computation, which is known to be suitable for the description of real-time applications. We take an open-source C/C++ implementation of ray-tracing and adapt it to KPN description in the Distributed Application Layer framework. Then, several possible configurations are evaluated in the target mobile computing platform (Exynos 5422), where eight heterogeneous ARM cores are integrated. We derive the optimal degree of parallelism and a suitable distribution of the replicated tasks tailored to the target architecture.
