Mechanism for enabling virtual method dispatch structures to be created on an as-needed basis
A mechanism is disclosed for enabling virtual method dispatch structures (vstructures) to be created on an as-needed basis. When an object class is loaded, a vstructure specific to that object class is not created. Rather, the vstructure for that object class is created only if and when a virtual method of that object class is invoked. By creating vstructures on an as-needed basis, the number of vstructures created during the execution of a program is minimized. This in turn reduces the number of vstructures that need to be updated whenever a reference to a method is changed (for example, as a result of a garbage collection operation). To further optimize the efficiency of the vstructure update process, vstructure entries that point to the same method may be linked. That way, when the reference to a method is changed, all vstructures affected by that change can be quickly identified. |

Facilitating stack read and write operations in a software transactional memory system
Various technologies and techniques facilitate stack read and write operations in a software transactional memory system. If the compiler determines that an address for a variable in a code segment is a stack location, the stack location is live on entry, and the address of the variable has not been taken and passed to another thread, the code is changed to ensure failure atomicity. One example includes modifying the code so a shadow copy is saved for local variables that are live on entry. If the same prior criteria are true except the stack location is not live on entry, the code is optimized by ensuring code for logging and software transactional memory operations are not included. If the compiler does not know the address is the stack location or that the address is not passed to another thread, the code is changed to ensure failure and concurrency atomicity. |

Continuous flow instant logic binary circuitry actively structured by code-generated pass transistor interconnects
A processing space contains an array of operational transistors interconnected by circuit and signal pass transistors that when supplied with selected enable bits will structure a variety of circuits that will carry out any desired information processing. The Babbage/von Neumann Paradigm in which data are provided to circuitry that would operate on those data is reversed by structuring the desired circuits at the site(s) of the data, thereby to eliminate the von Neumann bottleneck and substantially increase the computing power of the device, with the apparatus conducting only non-stop Information Processing on a steady stream of data and code, with no repetitious Instruction and data transfers as in the normal computer being required. A code is defined that will identify the physical locations of every transistor in the processing space, which code will then enable only selected ones of the pass transistors therein so as to structure the circuits needed for any algorithm sought to be executed. The circuits so structured, operating independently of and in parallel with every other circuit so structured, are then restructured after each step into another group of circuits, so that almost no transistor will ever “sit idle,” but all of the processing space can be devoted entirely to information processing, thereby again to increase enormously the computing power of the device. The apparatus is also super-scalable, meaning that an Instant Logic Apparatus built around that processing space could be built to have any size, speed, and level of computer power desired. |

Concurrent buffering and layer assignment in integrated circuit layout
A method and system for concurrent buffering and layer assignment in integrated current layout. Buffers are inserted and metal interconnects or “wires” are sized for every net, which consists of one driver and one or more receivers, such that timing skew constraints can be met. Long nets are promoted to a higher level if the slew violation can be fixed only by a promotion of the net or if the “slack” gain available by this promotion is equal to or greater than a predesignated layer of promotion threshold. In response to determining these layer assignments, the method and system then systematically demotes nets that are not critical and which do not impact the circuit and electrical constraints in order to minimize the use of high layer wire resources. |

To enable backward navigation, a descriptor file is created for a new version that contains not only a message digest for the new version, but also a message digest of the older document. A message digest is created for the descriptor file. A user navigates backward starting with the message digest of the descriptor file. To enable forward navigation, a mapping table maps a message digest of an older document into the message digest of the new version. A high-level descriptor file contains the message digest of the original document and the message digest of the mapping table. The message digest of the high-level descriptor file is returned to the user. A user navigates forward starting with the high-level descriptor file message digest. To enable circular navigation, a mapping table maps a message digest of a second document into a message digest of a version of the second document containing a message digest of a first document. The techniques are combined to allow navigation through a complex content space. |

Generating search results based on determined relationships between data objects and user connections to identified destinations
A search system generates an ordered list of destination targets including identified individuals and data objects, based on applying a user context to an information context and to a connection context. The user context identifies a search context (i.e., the information the user is seeking) relative to an identity of the user, and the information context identifies destinations accessible by the user, including data objects and communications-based actions (e.g., voice over IP telephony calls, instant messaging session transcripts, etc.). The connection context identifies relationships between chosen destinations throughout the system, and the strength of those relationships determined from artifacts of the chosen destinations: the connection context is updated based on artifact detection. The portion of the connection context that is relevant to the user context is used to order the portion of the information context that is relevant to the user context, resulting in the ordered list of destination targets. |

Packet sequence maintenance with load balancing, and head-of-line blocking avoidance in a switch
To avoid packet out-of-sequence problems, while providing good load balancing, each input port of a switch monitors the outstanding number of packets for each flow group. If there is an outstanding packet in the switch fabric, the following packets of the same flow group should follow the same path. If there is no outstanding packet of the same flow group in the switch fabric, the (first, and therefore subsequent) packets of the flow can choose a less congested path to improve load balancing performance without causing an out-of-sequence problem. To avoid HOL blocking without requiring too many queues, an input module may include two stages of buffers. The first buffer stage may be a virtual output queue (VOQ) and second buffer stage may be a virtual path queue (VPQ). At the first stage, the packets may be stored at the VOQs, and the HOL packet of each VOQ may be sent to the VPQ. By allowing each VOQ to send at most one packet to VPQ, HOL blocking can be mitigated dramatically. |
