Abstract: In a massively parallel computing system having a plurality of nodes configured in m multi-dimensions, each node including a computing device, a method for routing packets towards their destination nodes is provided which includes generating at least one of a 2m plurality of compact bit vectors (115, 154) containing information derived from downstream nodes. A multileve l arbitration process (116, 155) in which downstream information stored in the compact vectors, such as link status information and fullness of downstream buffers (130, 140), is used to determine a preferred direction and virtual channel for packet transmission. Preferred direction ranges are encoded and virtual channels are selected by examining the plurality of compact bit vectors (115, 154). This dynamic routing method eliminates the necessity of routing tables, thus enhancing scalability of the switch.

Particularly, a global interrupt and barrier network is implement ed that implements logic for generating global interrupt and barrier signals fo r controlling global asynchronous operations perfomed by processing elements a t selected processing nodes (12) of computing structure in accordance with a processing algorithm; and includes the physical interconnecting of the processing nodes (12) for communicating the global interrupt and barrier signals to the elements via low latency paths. The global asynchronous signa ls respectively initiate interrupt and barrier operations at the processing nod es (12) at times selected for otpimizing performance of the processing algorithms. In one embodiment, the global interrupt and barrier network is implemented in a scalable, massively parallel supercomputing device structur e comprising a plurality of processing nodes interconnected by multiple independent networks.

Abstract: Class network routing is implemented in a network such as a computer network comprising a plurality of parallel compute processors at nodes thereof. Class network routing allows a compute processor to broadcast a message to a range (one or more) of other compute processors in the computer network, such as processors in a column or a row. Normally this type of operation requires a separate message to be sent to each processor. With class network routing pursuant to the invention, a single message is sufficient, which generally reduces the total number of messages in the network as well as the latency to do a broadcast, Class network routing is also applied to dense matrix inversion algorithms on distributed memory parallel supercomputers with hardware class function (multicast) capability. This is achieved by exploiting the fact that the communication patterns of dense matrix inversion can be served by hardware class functions, which results in faster execution times.

Abstract: Methods and systems for performing arithmetic functions. In accordance with a first aspect of the invention, methods and apparatus are provided, working i n conjunction of software algorithms and hardware implementation of class network routing, to achieve a very significant reduction in the time require d for global arithmetic operation on the torus. Therefore, it leads to greater scalability of applications running on large parallel machines. The inventio n involves three steps in improving the efficiency and accuracy of global operations: (1) Ensuring, when necessary, that all the nodes do the global operation on the data in the same order and so obtain a unique answer, independent of roundoff error; (2) Using the topology of the torus to minimi ze the number of hops and the bidirectional capabilities of the network to redu ce the number of time steps in the data transfer operation to an absolute minimum; and (3) Using class function routing to reduce latency in the data transfer. With the method of this invention, every single element is injecte d into the network only once and it will be stored and forwarded without any further software overhead. In accordance with a second aspect of the invention, methods and systems are provided to efficiently implement global arithmetic operations on a network that supports the global combining operations. The latency of doing such global operations are greatly reduced by using these methods (Figure 4, node0, node1, node2, node3).
