Tuned and asynchronous stencil kernels for CPU/GPU systems

Tuned and asynchronous stencil kernels for CPU/GPU systems

We describe heterogeneous multi-CPU and multi-GPU implementations of Jacobi's iterative method for the 2-D Poisson equation on a structured grid, in both single- and double-precision. Properly tuned, our best implementation achieves 98% of the empirical streaming GPU bandwidth (66% of peak) on...
