Stencil computations are at the core of applications in many domains such as computational electromagnetics, image processing, and partial differential equation solvers used in a variety of scientific and engineering applicatio ns. Short-vector SIMD instruction sets such as SSE and VMX provide a promis ing and widely available avenue for enhancing performance on modern pr ocessors. However a fundamental memory stream alignment issue limits achieved pe rformance with stencil computations on… CONTINUE READING
