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: In a massively parallel system, a method and apparatus for uniquely assigning a MAC address(400) to a device encodes the MAC address with a physical location of the device(410). The method and apparatus include configuring device interconnections of the parallel system with physical topological information such as a rack number, a midplane number, a card number, and a chip number. A device or node with a physical location encoded MAC address may then be interrogated by location for test, diagnostic, and program loading purposes.

Abstract: A system and method for generating global asynchronous signals in a computin g structure. 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: A low latency memory system access is provided in association with a weakly- ordered multiprocessor system(Fig.1). Each processor(12-1, 12-2) in the multiprocessor shares resources, and each shared resource has an associated lock within a locking device(10) that provides support for synchronization between the multiple processors(12-1, 12-2) in the multiprocessor and the orderly sharing of the resources. A processor(12-1, 12-2) only has permissio n to access a resource when it owns the lock associated with that resource, an d an attempt by a processor(12-1, 12-2) to own a l ock requires only a single load operation, rather than a traditional atomic load followed by store, suc h that the processor(12-1, 12-2) only performs a read operation and the hardwa re locking device(10) performs a subsequent write operation rather than the processor(12-1, 12-2).

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.
