  • 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.

  • Local bypass for in memory computing
    Patent number: 9390038
    Abstract: Embodiments include a method for bypassing data in an active memory device. The method includes a requestor determining a number of transfers to a grantor that have not been communicated to the grantor, requesting to the interconnect network that the bypass path be used for the transfers based on the number of transfers meeting a threshold and communicating the transfers via the bypass path to the grantor based on the request, the interconnect network granting control of the grantor in response to the request. The method also includes the interconnect network requesting control of the grantor based on an event and communicating delayed transfers via the interconnect network from other requestors, the delayed transfers being delayed due to the grantor being previously controlled by the requestor, the communicating based on the control of the grantor being changed back to the interconnect network.

  • Testing and operating a multiprocessor chip with processor redundancy
    Patent number: 8868975
    Abstract: A system and method for improving the yield rate of a multiprocessor semiconductor chip that includes primary processor cores and one or more redundant processor cores. A first tester conducts a first test on one or more processor cores, and encodes results of the first test in an on-chip non-volatile memory. A second tester conducts a second test on the processor cores, and encodes results of the second test in an external non-volatile storage device. An override bit of a multiplexer is set if a processor core fails the second test. In response to the override bit, the multiplexer selects a physical-to-logical mapping of processor IDs according to one of: the encoded results in the memory device or the encoded results in the external storage device. On-chip logic configures the processor cores according to the selected physical-to-logical mapping.
