Abstract: A method and system is provided for a message queuing computer to automatically determine system topology information regarding its location in a message queuing system. Such topology information includes a message queuing address that may include a message queuing site and a message queuing connected network on which the message queuing computer currently resides. Upon initialization of its message queuing software, the message queuing computer determines if there have been changes in its transport network indicating that it has moved to a new location in the message queuing system. If so, the message queuing computer broadcasts a request for potentially existing message queuing servers around it to provide the topology information concerning its current location. If no reply to the broadcast request is received, the computer sends a datagram to a server at a known network address for the topology information.

Abstract: A system for accessing information stored in a distributed information database provides a community of intelligent software agents. Each agent can be built as an extension of a known viewer for a distributed information system such as the Internet WorldWide Web. The agent is effectively integrated with the viewer and can extract pages by means of the viewer for storage in an intelligent page store. The text from the information system is abstracted and is stored with additional information, optionally selected by the user. The agent-based access system uses keyword sets to locate information of interest to a user, together with user profiles such that pages being stored by one user can be notified to another whose profile indicates potential interest. The keyword sets can be extended by use of a thesaurus.

At power-up, boot code stored in the non-volatile memory is executed and begins instantiating the initial operating environment of the embedded computer system.

Abstract: There is provided a method of passing information between two or more information handling devices, such as a printer, a personal computer or a scanner. There exists a means for communication of information such as network with network connection means between the information handling devices. Each passage of information consists of one or more interactions from an interaction set, none of the interactions of the interaction set being dependent on the function to be carried out on the information by any of the information handling devices. This is particularly advantageous where each passage of information relates to sharing of a surface between a first device and one or more second devices, wherein the surface is a representation of an internal state of the first device.

Abstract: A computer-based custom marshaling method and system for custom marshaling of parameters during invocation of functions implemented in a second language by computer programs implemented in an first language. The parameter to be custom marshaled has a first type in the first language and a second type in the second language. The custom marshaling system receives code for converting a parameter of the first type to a parameter of the second type and for converting a parameter of the second type to a parameter of the first type. The custom marshaling system monitors the execution of a computer program implemented in the first language that invokes a function implemented in the second language. The invocation passes a parameter of the first type, and the function expects a parameter of the second type. The custom marshaling system intercepts the invocation of the function implemented in the second language.

Abstract: A system and method for updating packet headers using hardware that maintains the high performance of the network element. In one embodiment, the system includes an input port process (IPP) that buffers the input packet received and forwards header information to the search engine. The search engine searches a database maintained on the switch element to determine the type of the packet. In one embodiment, the type may indicate whether the packet can be routed in hardware. In another embodiment, the type may indicate whether the packet supports VLANs. The search engine sends the packet type information to the IPP along with the destination address (DA) to be updated if the packet is to be routed, or a VLAN tag if the packet has been identified to be forwarded to a particular VLAN. The IPP, during transmission of the packet to a packet memory selectively replaces the corresponding fields, e.g., DA field or VLAN tag field; the modified packet is stored in the packet memory.

Abstract: A computer instruction execution unit includes different execution paths for different categories of instructions. Different execution paths share circuitry. The slower execution paths are pipelined. In some embodiments, all execution paths are pipelined. Fast instructions are executed by a fast execution path. Slower instructions are executed by a slower execution path. Faster instructions immediately following the slower instruction are also executed by the slower execution path not to block the shared circuitry. Consequently, the throughput is increased and the average instruction execution latency is reduced. When a sufficient number of clock cycles accumulate with no instructions started, subsequent fast instructions are executed by the fast execution path. A floating point multiplier is provided in which normalization/denormalization shift amounts are generated in parallel with multiplication of the significands of the operands.

Abstract: Apparatus and method to improve the speed of electronic file transfer between remote computers by parallel processing. The most common transfer protocol is the File Transfer Protocol (FTP) Though the Internet is the most popular means by which users electronically transport data, the Internet's Transport Control Protocol/Internet Protocol ("TCP/IP") model, upon which FTP operates, does not adequately support the transfer of large data sets over long distances. Typical transfers between distant sites linked via the Internet have throughputs of about 20 Kilobytes per second ("Kb/sec") or less, and they are prone to dropping packets or losing connections. Making FTP parallel makes transfers up to five times faster, that is, it offers transfer rates of up to 100 Kb/sec. FTP is operated in parallel by segmenting a file into discrete packets, simultaneously transmitting these packets to the receiving computer, and reassembling the packets into the original file.

Abstract: A total impurity concentration which is a result of the solution of a diffusion equation at the immediately preceding point of time is used to solve, for each mesh point, an equation for determining an electrically active impurity concentration to approximately determine an electrically active impurity concentration. A ratio between the approximate value of the electrically active impurity concentration and the total concentration of the impurities at the preceding point of time is determined for each mesh point. A value of the ratio is determined by interpolating values at mesh points at the opposite ends of each mesh branch. A diffusion equation which includes the total concentration of the impurities as a variable and employs an effective diffusion constant is solved to determine a total impurity concentration at the present point of time of analysis.
