Utilizing heterogeneous platforms for computation has become a general trend making the portability issue important. OpenCL (Open Computing Language) serves the purpose by enabling portable execution on heterogeneous architectures. However, unpredictable performance variation on different platforms has become a burden for programmers who write OpenCL programs. This is especially true for conventional multi-core CPUs, since the performance of general OpenCL applications on CPUs lags behind the performance expected by the programmer considering the conventional parallel programming model.
