To program such heterogeneous systems, OpenCL has become an industry standard due to the portability across various computing architectures. To exploit the computing capabilities of heterogeneous systems, application developers are porting their cluster and Cloud applications using OpenCL. With the increasing number of such applications, the use of shared accelerating computing devices (such as CPUs and GPUs) should be managed using an efficient load-balancing scheduling heuristic capable of reducingexecution time, increasing throughput with high device utilization. Mostly, the OpenCL applications are suited (execute faster) on a specific computing device (CPU or GPU) and with varying data-sizes the speedup obtained by an application on the suitable device varies too. Applications{\textquoteright} mapping to computing devices without considering device suitability and obtainable speedup on a suitable device leads to sub-optimal execution time, lower throughput and load imbalance. Therefore, an application scheduler should consider both the device-suitability and speedup variation for scheduling decisions leading to a reduction in execution time and an increase in throughput. In this paper, we present a novel load-balancing scheduling heuristic named as Troodon that considers machinelearning based device-suitability model that classify OpenCL applications into either CPU suitable or GPU suitable. Moreover, a speedup predictor that predicts the amount of speedup that jobs will obtain when executed on a suitable device is also part of the Troodon. Troodon incorporates the E-OSched scheduling mechanism to map jobs on CPU and GPUs in a load balanced way. This results in reduced applications execution time, increased system throughput, and improved device utilization. We evaluate the proposed scheduler using a large number of data-parallel applications and compared with several other state-of-the-art scheduling heuristics. The experimental evaluation has demonstrated that the proposed scheduler outperformed the existing heuristics and reduced the application execution time up to 38% with increased system throughput and device utilization.",
