摘要： One embodiment of the present invention provides a system that facilitates avoiding locks by speculatively executing critical sections of code. During operation, the system allows a process to speculatively execute a critical section of code within a program without first acquiring a lock associated with the critical section. If the process subsequently completes the critical section without encountering an interfering data access from another process, the system commits changes made during the speculative execution, and resumes normal non-speculative execution of the program past the critical section. Otherwise, if an interfering data access from another process is encountered during execution of the critical section, the system discards changes made during the speculative execution, and attempts to re-execute the critical section.
摘要翻译：本发明的一个实施例提供一种通过推测性地执行代码的关键部分来有助于避免锁定的系统。在操作期间，系统允许进程在程序中推测性地执行代码的关键部分而不首先获得与关键部分相关联的锁定。如果该过程随后完成关键部分而没有遇到来自另一进程的干扰数据访问，则系统进行在推测执行期间所做的更改，并且通过关键部分恢复程序的正常非推测性执行。否则，如果在执行关键部分期间遇到来自其他进程的干扰数据访问，则系统将丢弃在推测执行期间所做的更改，并尝试重新执行临界部分。

摘要： Control symbols taking the form {k1-k2-k2-k1} are inserted in a serial stream including m bit data words. k1 and k2 are each predefined m bit control words differing from the m bit data words. The Hamming distance between k1 and k2 is at least 2. Such control symbols may be robustly detected in the presence of a one bit error in the symbol, or a data word immediately preceding or following the symbol. The m bit words may be 8B/10B encoded data, or defined control words. The control symbols may be used for data delineation, stream synchronizaiton, transmitter/receiver synchronization or for other control signalling.
摘要翻译：采用形式{k1-k2-k2-k1}的控制符号被插入到包括m位数据字的串行流中。 k1和k2是与m位数据字不同的预定义的m位控制字。 k1和k2之间的汉明距离至少为2.这样的控制符号可以在符号中存在一位错误或紧接在符号之前或之后的数据字的情况下被鲁棒地检测。 m位字可以是8B / 10B编码数据或定义的控制字。控制符号可用于数据描绘，流同步，发射机/接收机同步或用于其他控制信令。

摘要： The cache coherency protocol described herein can be used to maintain a virtual model of a system, where the virtual model does not change as the system configuration changes. In general, the virtual model is based on the assumption that each node in the system can directly communicate with some number of other nodes in the system. In one embodiment, for each cache line, the address of the cache line is used to designate a node as the “home” node and all other nodes as “peer” nodes. The protocol specifies one set of messages for communication with the line's home node and another set of messages for communication with the line's peer nodes.

摘要： A distributed memory computer architecture associates separate memory blocks with their own processors, each of which executes the same program. A processor fetching data or instructions from its local memory also broadcasts that fetched data or instruction to the other processors to cut the time required for them to request this data. Runs of instruction and data local to one processor providing improved performance that is captured by the system as a whole by the ability of the other processors not executing local data or instructions to execute instructions out of order and return to find the data ready in buffer for rapid use.

摘要： A method of reducing soluble Cr(VI) levels in aqueous wastes from 200 ppm or more to less than 1 ppm, particularly to less than 0.05 ppm, preferably to less than 0.01 ppm, uses fermentative sulfate-reudcing anaerobic bacteria to reduce Cr(VI) to Cr(III) and immobilize the latter as the extememly insoluble hydroxide. The process is readily adapted to operate continuously using a bioreactor containing sludge with sulfate-reducing anaerobic bacteria and operated as a chemostat.

摘要： An alarm control circuit, designed as a unit package to be mounted in the interior of a vehicle, is adapted for connection to the ignition switch circuit, to a vehicle door or other closure operated light switch circuit, and to the vehicle battery, with the output being connected to the vehicle horn circuit. The alarm control circuit is completely automatic when operated through the vehicle ignition switch and a vehicle closure switch, and sounds the vehicle horn intermittently when a closure is opened by unauthorized persons. The alarm control circuit may also be connected to the vehicle headlight switch circuit to provide the ancillary function of a warning signal, should the headlights be left on with the ignition switch off.

摘要： A conflict resolution technique provides consistency such that all conflicts can be detected by at least one of the conflicting requestors if each node monitors all requests after that node has made its own request. If a line is in the Exclusive, Modified or Forward state, conflicts are resolved at the node holding the unique copy. The winner of the conflict resolution, and possibly the losers, report the conflict to the home node, which pairs conflict reports and issues forwarding instructions to assure that all requesting nodes eventually receive the requested data. If a requested cache line is either uncached or present only in the Shared state, the home node provides a copy of the cache node and resolves conflicts. In one embodiment, a blackout period after all responses until an acknowledgement message has been received allows all conflicting nodes to be aware of conflicts in which they are involved.
摘要翻译：冲突解决技术提供一致性，使得如果每个节点在该节点已经做出其自己的请求之后监视所有请求，则冲突请求者中的至少一个可以检测所有冲突。如果一行处于“独占”，“修改”或“转发”状态，则在保存唯一副本的节点处解决冲突。冲突解决的胜利者以及可能的失败者将冲突报告给家庭节点，该家庭节点对冲突报告和发出转发指令，以确保所有请求节点最终都接收到所请求的数据。如果所请求的高速缓存行未被缓存或仅在共享状态下存在，则家庭节点提供缓存节点的副本并解决冲突。在一个实施例中，在接收到确认消息之后的所有响应之后的停电时段允许所有冲突节点都知道它们涉及的冲突。

摘要： Described herein is a cache coherency protocol having five states: Modified, Exclusive, Shared, Invalid and Forward (MESIF). The MESIF cache coherency protocol includes a Forward (F) state that designates a single copy of data from which further copies can be made. A cache line in the F state is used to respond to request for a copy of the cache line. In one embodiment, the newly created copy is placed in the F state and the cache line previously in the F state is put in the Shared (S) state, or the Invalid (I) state. Thus, if the cache line is shared, one shared copy is in the F state and the remaining copies of the cache line are in the S state.
摘要翻译：这里描述了具有五种状态的高速缓存一致性协议：修改，独占，共享，无效和转发（MESIF）。 MESIF高速缓存一致性协议包括转发（F）状态，其指定可以进行进一步复制的数据的单个副本。 F状态的高速缓存行用于响应缓存行副本的请求。在一个实施例中，新创建的副本被置于F状态，并且先前处于F状态的高速缓存行被置于共享（S）状态或无效（I）状态。因此，如果高速缓存行被共享，则一个共享副本处于F状态，并且高速缓存行的剩余副本处于S状态。

摘要： Critical sections of a program, providing exclusive access to shared data in a multi-processor architecture may be inferred from standard instructions and used to invoke a cache protocol that delays the response of requests of other cache and thus counter intuitively improving performance of the system. During this delay, read-only copies of data may be provided and the delay may recognize two priorities of requests, one of which is not delayed so as to improve the release of locks held by different processors.

摘要： A mechanical seal assembly is provided for inhibiting a fluid located in a higher pressure region of an apparatus from flowing to a relatively lower pressure region. The seal assembly is configured for cooperation with a seal ring connected to a cylindrical shaft which rotates about its longitudinal axis and which is mounted in the apparatus housing. The seal assembly includes an outer casing in which is mounted a non-rotatable seal ring which encircles the shaft for limited axial movement toward and away from the shaft seal ring. A biassing element is mounted in the outer casing for urging the non-rotatable seal ring axially into slidably mating engagement with the sealing face of the rotatable shaft seal ring. The biassing element includes a cylindrical bellows which encircles the shaft and a spring. The bellows includes a collapsible outer wall with a first skirt on one end of the outer wall and a second skirt on the other end of the outer wall. The first skirt is bonded to the seal ring, and the second skirt is clamped axially against the outer casing end wall.
