If you do this, you may have problems with deadlock due to lack of queue space along the path of the message. One reason for using the routing algorithm described by pase in his article is that the algorithm is proven to be deadlock free provided that the destination node will eventually consumes all messages it receives. This particular routing algorithm is call the e-cube routing algorithm. +--------------------------------------------------------------------------+ | Wen-King Su wen-king@vlsi.caltech.edu Caltech Corp of Cosmic Engineers | +--------------------------------------------------------------------------+
