Description
Summary:This paper presents the Load Balancing for OpenCL (lbcl) library, devoted to automatically solve load balancing issues on both multi-platform and heterogeneous environments. Using this library, a single kernel can be executed on a set of heterogeneous devices, giving each device an amount of work proportional to its computing power. A wrapper has been developed so the library can balance the workload of an existing application not only without introducing any changes into its source code, but without any recompilation stage. Also a general OpenCL profiler has been developed to easily do a detailed profiling of the obtained results.
