  • Data communications in a distributed computing environment
    Patent number: 10277547
    Abstract: Data communications may be carried out in a distributed computing environment that includes a plurality of computers coupled for data communications through communications adapters and an active messaging interface (‘AMI’). In distributed computing environment, data communications may include: receiving in the AMI from an application an eager SEND instruction that describes the location and size of send data in an application SEND buffer; copying by the AMI the send data from the application SEND buffer to a temporary AMI buffer; advising the application of completion of the SEND instruction before sending the SEND data to the receiver; and after advising the application of completion of the SEND instruction, sending the SEND data by the sender to the receiver.

  • Multi-petascale highly efficient parallel supercomputer
    Patent number: 9971713
    Abstract: A Multi-Petascale Highly Efficient Parallel Supercomputer of 100 petaflop-scale includes node architectures based upon System-On-a-Chip technology, where each processing node comprises a single Application Specific Integrated Circuit (ASIC). The ASIC nodes are interconnected by a five dimensional torus network that optimally maximize the throughput of packet communications between nodes and minimize latency. The network implements collective network and a global asynchronous network that provides global barrier and notification functions. Integrated in the node design include a list-based prefetcher. The memory system implements transaction memory, thread level speculation, and multiversioning cache that improves soft error rate at the same time and supports DMA functionality allowing for parallel processing message-passing.
