Abstract
We evaluate workload distribution optimization between an Android phone, a cloud service by considering the overall impact of both computation, data transfer. We use OpenCL parallelism on Android to obtain high computation performance. We implement an escape time algorithm to compute the Mandelbrot set with OpenCL,, with Java as a reference for comparison. In an experiment of setting the escape boundary at 256, OpenCL offers about 5.0X to 7.5X faster computation compared to Java. With a cloud service, data transfer becomes a dominant factor when the amount of computation is low. In a set of four experiments of sharing workload of computing the Mandelbrot set between a cloud service, a phone, data transfer consumes on average over 80% of processing time. In those experiments computing locally with OpenCL on an Android phone yields faster processing time. On the other hand, local computation capacity becomes a bottleneck when the amount of computation is high. With the escape boundary at 65536, requesting computation from a cloud service yields up to 7.55X speedup.
