Enhancing vector access performance in CRAY X-MP memory system
S. Edirisooriya, Geetani Edirisooriya · 2002
The authors propose a simple modification to the conflict resolution scheme that will significantly improve the performance of the CRAY X-MP memory system. In particular, they show that it is possible to avoid linked conflicts due to a single CPU altogether by changing the priorities of active vector streams when a memory port encounters a memory bank conflict. Some examples are presented to show how the proposed scheme prevents these linked conflicts.>
