Stencil computation arises from a broad set of scientific and engineering applications and often plays a critical role in the performance of extreme-scale simulations. Due to the memory bound nature, it is a challenging task to opti- mize stencil computation kernels on modern supercomputers with relatively high computing throughput whilst relatively low data-moving capability. This work serves as...
With the innovation of IBM POWER processors as well as the rapid development of OpenPOWER league, a part of future supercomputers in 100P level would adopt POWER as CPU processors. As hardware features of POWER8 have been studied in these years, the lack of tuning guidelines indicates a gap between software performance and hardware capabilities. To fully evaluate the POWER8 processor and provide tuning...
In this paper we choose the widely used Jacobi stencil algorithm as our target program to evaluate the effectiveness of tuning techniques based on the latest POWER8 processor, thus to provide optimization guidelines to similar stencil based algorithms.
