Graphics Processing Units (GPUs) have been accepted as a powerful and viable coprocessor solution in high-performance computing domain. In order to maximize the benefit of GPUs for a multicore platform, a mechanism is needed for CPU threads in a parallel application to share this computing resource for efficient execution. NVIDIA's Fermi architecture pioneers the feature of concurrent kernel execution; however, only kernels of the same thread context can execute in parallel. In order to get the best use of a GPU device in a multi-threaded application environment, this paper explores the techniques to effectively share a context.
