The patterns covering the face of the rectangular block also represent a previously unknown ancient writing system ? a rare find in archaeology 布于矩形石板的图案,显示了一种以前未知的古老文字系统? ?一个罕见的考古学发现。
In wormhole meshes , a reliable routing is supposed to be deadlock - free and fault - tolerant . many routing algorithms are able to tolerate a large number of faults enclosed by rectangular blocks or special convex , none of them , however , is capable of handling two convex fault regions with distance two by using only two virtual networks 在应用虫孔路由的mesh结构的多处理机系统中,已经有许多基于维数序的容错的路由算法被提出,其中大多数路由算法只能容忍矩型或凸型的故障节点组成的区域,但是,至今还没有一个算法能应用两个虚拟信道处理凸型convex故障区域距离大于和等于2的情况。
