Competitiveness of a Non-Linear Block-Space GPU Thread Map for Simplex Domains.

This work presents and studies the efficiency problem of mapping GPU threads onto simplex domains. A non-linear map $\lambda (\omega)$ is formulated based on a block-space enumeration principle that reduces the number of thread-blocks by a factor of approximately $2\times$ and $6\times$ for 2-simplex and 3-simplex domains, respectively, when compared to the standard approach. Performance resul...
