  • 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.

  • Method of entropy randomization on a parallel computer
    Patent number: 9335970
    Abstract: Method, system, and computer program product for randomizing entropy on a parallel computing system using network arithmetic logic units (ALUs). In one embodiment, network ALUs on nodes of the parallel computing system pseudorandomly modify entropy data during broadcast operations through application of arithmetic and/or logic operations. That is, each compute node's ALU may modify the entropy data during broadcasts, thereby mixing, and thus improving, the entropy data with every hop of entropy data packets from one node to another. At each compute node, the respective ALUs may further deposit modified entropy data in, e.g., local entropy pools such that software running on the compute nodes and needing entropy data may fetch it from the entropy pools. In some embodiments, entropy data may be broadcast via dedicated packets or included in unused portions of existing broadcast packets.

  • Adding entropy for improved random number generation in a computer system
    Patent number: 8745114
    Abstract: A parallel computer system adds entropy to improve the quality of random number generation by using parity errors as a source of entropy because parity errors are influenced by external forces such as cosmic ray bombardment, alpha particle emission, and other random or near-random events. By using parity errors and associated information to generate entropy, the quality of random number generation in a parallel computer system is increased.
