CRANIUM: An Interface for Message Passing on Adaptive Packet Routing Networks
نویسندگان
چکیده
Cranium is a processor-network interface for an intercon-nection network based on adaptive packet routing. Adaptive networks relax the restriction that packet order is preserved; packets may be delivered to their destinations in an arbitrary sequence. Cranium uses two mechanisms: an automatic-receive interface for packet serialization and high performance, and a processor-initiated interface for exibility. To minimize software overhead, Cranium is directly accessible by user-level programs. Protection for user-level message passing is implemented by mapping user-level handles into physical node identiiers and buuer addresses .

Enforcing In-Order Packet Delivery in PC Clusters using Adaptive Routing
Adaptive routing has been widely studied for interconnection networks in massively parallel computers and system area networks (SAN). Adaptive routing dynamically selects the path followed by packets, thus providing high network throughput. However, it may deliver packets out-of-order, which some message passing libraries don’t accept. In this paper, we propose a mechanism for guaranteeing in-o...

Adaptive routing, which dynamically selects the route of a packet, has been widely studied for interconnection networks in massively parallel computers and system area networks. Although adaptive routing has the advantage of providing high bandwidth, it may deliver packets out-of-order, which some message passing libraries don’t accept. In this paper, we propose two mechanisms called 1) FIFO tr...

متن کاملPerformance Analysis of a New Neural Network for Routing in Mesh Interconnection Networks
Routing is one of the basic parts of a message passing multiprocessor system. The routing procedure has a great impact on the efficiency of a system. Neural algorithms that are currently in use for computer networks require a large number of neurons. If a specific topology of a multiprocessor network is considered, the number of neurons can be reduced. In this paper a new recurrent neural ne...
