摘要:
A method and system for the capture of data files transmitted over a wired network by a data traffic generator. The mapping and/or translation of network addressing data contained within the captured data frames is such that the frames, when transferred over the wireless medium, appear to have originated from one of a population of emulated wireless stations. The mapping and/or translation of network addressing data contained in data frames received over the wireless medium directed to a specific emulated wireless station is such that the frames, when transmitted over the wired network, appear to be destined for the data traffic generator. The mapping and/or translation function is applied as frames traverse the boundary between the external data source network interface and the wireless network interface.

An induction furnace capable of operation at temperatures of over 3100° C. has a cooling assembly (60), which is selectively mounted to an upper end of the furnace wall (76). The cooling assembly includes a dome (62), which is actively cooled by cooling water coils (68). During the cool-down portion of a furnace run, cooling initially proceeds naturally, by conduction of heat away from the hot zone through a furnace insulation layer (58). Once the temperature within the furnace hot zone (20) reaches about 1500° C., a lifting mechanism (80), mounted to the dome, raises a cap (16) of the furnace slightly, allowing hot gases from the hot zone to mix with cooler gas in the dome. This speeds up cooling of the hot zone, reducing cool-down times significantly, without the need for encumbering the furnace itself with valves or other complex cooling mechanisms which have to be replaced periodically. The life of a graphite furnace susceptor (10) at the high operating temperature is increased by surrounding the susceptor with a barrier layer (40) of flexible graphite, which inhibits evaporation of the graphite. Additionally, witness disks (154), placed within the susceptor, provide an accurate temperature profile of the hot zone.

A shared address space on a compute node stores data received from a network and data to transmit to the network. The shared address space includes an application buffer that can be directly operated upon by a plurality of processes, for instance, running on different cores on the compute node. A shared counter is used for one or more of signaling arrival of the data across the plurality of processes running on the compute node, signaling completion of an operation performed by one or more of the plurality of processes, obtaining reservation slots by one or more of the plurality of processes, or combinations thereof.

A system and method for enhancing barrier collective synchronization on a computer system comprises a computer system including a data storage device. The computer system includes a program stored in the data storage device and steps of the program being executed by a processor. The system includes providing a plurality of communicators for storing state information for a bather algorithm. Each communicator designates a master core in a multi-processor environment of the computer system. The system allocates or designates one counter for each of a plurality of threads. The system configures a table with a number of entries equal to the maximum number of threads. The system sets a table entry with an ID associated with a communicator when a process thread initiates a collective. The system determines an allocated or designated counter by searching entries in the table.

There is presented a system and method for providing real-time object recognition to a remote user. The system comprises a portable communication device including a camera, at least one client-server host device remote from and accessible by the portable communication device over a network, and a recognition database accessible by the client-server host device or devices. A recognition application residing on the client-server host device or devices is capable of utilizing the recognition database to provide real-time object recognition of visual imagery captured using the portable communication device to the remote user of the portable communication device. In one embodiment, a sighted assistant shares an augmented reality panorama with a visually impaired user of the portable communication device where the panorama is constructed from sensor data from the device.
摘要:
A method and article for efficiently accessing resources in a multiprocessor computer system. Multiple resources are grouped into nodes and system resource descriptors are maintained as data structures. The method incorporates traversing one or more of the data structure to efficiently allocate resources within a grouping of nodes. Each node in the system is assigned a node identifying number. This number identifies a node location within a multiprocessor and is used to determine latency between nodes. Accordingly, storing the system architecture information in a data structure format provides for an efficient method of accessing system resources and determining latency for specific processes and access patterns.

A piston cartridge having a piston chamber, an inlet port, an outlet port, and a piston moveable between a first position and a second position. Also, the cartridge includes a first barrier positioned between the piston and the inlet port and a first sealing member moveable between the first barrier and the inlet port, wherein the first sealing member seals the inlet port when positioned adjacent to the inlet port but allows the fluid into the chamber when positioned adjacent to the first barrier. In addition, the cartridge also includes a second barrier positioned adjacent to the outlet port and a second sealing member moveable between the piston and the second barrier, wherein the second sealing member seals the outlet port when positioned adjacent thereto but allows the fluid to pass through the outlet port when positioned adjacent to the second barrier.

摘要:
A method and computer system for efficiently accessing resources in a multiprocessor computer system. Multiple resources are grouped into nodes and system resource descriptors are maintained as data structures. The method incorporates traversing a data structure to efficiently allocate resources within a grouping of nodes. Each node in the system is assigned a node identifying number. This number identifies a node location within a multiprocessor and is used to determine latency between nodes, either through an average latency table or a system interconnect connection table. The data structure comprises secondary data structures therein for storing processor, bus, memory and shared cache information. The data structure includes pointers to each of the secondary data structures. In addition, each node or grouping of nodes may include subnodes. As such, the system provides for a method of recursively accessing additional data structure levels for each level of nodes and/or subnodes in the system. In addition to the data structure and the secondary data structure, the system includes a memory map in the form of a data structure. This data structure stores information as to which node a given block of memory address space is located in. In addition, there is a flag for each memory block indicating whether the memory address is parity or error correcting code (ECC), or neither parity nor ECC protected. This flag is in the form of two bits for indicating the level of memory protection provided to a specific block of memory address. Accordingly, storing the system architecture information in a data structure format provides for an efficient method of accessing system resources and determining latency for specific processes and access patterns.
