Open the CIPO recordAbstract From the Canadian patent
A massively parallel computer system (500) is disclosed having a global router network in which pipeline registers are spatially distributed to increase the messaging speed of the global router network. The global router network includes an expansion tap for processor to I/O (1700) messaging so that I/O messaging bandwidth matches interprocessor messaging bandwidth. A route-opening message packet includes protocol bits which are treated homogeneously with steering bits. The route-opening packet further includes redundant address bits for imparting a multiple-crossbars personality to router chips within the global router network. A structure and method for spatially supporting the …

Why it's free to use
- Filed January 4, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 4, 2011.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
