1894   On Low-Dimensional Galerkin Models for Fluid Flow On Low-Dimensional Galerkin Models for Fluid Flow D. Rempfer    2000 In this paper some implications of the technique of projecting the Navier–Stokes equations onto low-dimensional bases of eigenfunctions are explored. Such low-dimensional bases are typically obtained by truncating a particularly well-suited complete set of eigenfunctions at very low orders, arguing that a small number of such eigenmodes already captures a large part of the dynamics of the system. In addition, in the treatment of inhomogeneous spatial directions of a... 查看全文

1895   Understanding the efflciency of ray traversal on GPUs Understanding the efflciency of ray traversal on GPUs    2009 We discuss the mapping of elementary ray tracing operations - acceleration structure traversal and primitive intersection - onto wide SIMD/SIMT machines. Our focus is on NVIDIA GPUs, but some of the observations should be valid for other wide machines as well. While several fast GPU tracing methods have been published, very little is actually understood about their performance. Nobody knows whether the methods are anywhere near the theoretically obtainable limits, and if not, what might be causi... 查看全文
