摘要： A method includes sending over the network from a source entity to a destination entity a sequence of a plurality of packets. Each packet in the sequence includes a same identifier corresponding to a network entity on the network. Sending includes modifying a property of the sequence of packets to uniquely identify the sequence of packets. The method includes receiving information indicating the identifier corresponds to the modification of the property. Another method includes examining a sequence of packets sent over a network from a source entity to a destination entity, each packet in the sequence comprising a same identifier corresponding to a network entity on the network. The method includes determining whether a property of the sequence of packets was modified when sent to uniquely identify the sequence of packets; and responsive to the determining, associating the identifier with the network identity. Apparatus and program products are also disclosed.

摘要： A method and apparatus for fine-grained filtering in a hardware accelerated software transactional memory system is herein described. A data object, which may have any arbitrary size, is associated with a filter word. The filter word is in a first default state when no access, such as a read, from the data object has occurred during a pendancy of a transaction. Upon encountering a first access, such as a first read, from the data object, access barrier operations including an ephemeral/private store operation to set the filter word to a second state are performed. Upon a subsequent/redundant access, such as a second read, the access barrier operations are elided to accelerate the subsequent access, based on the filter word being set to the second state to indicate a previous access occurred.

摘要： One embodiment of the present invention supports execution of a start transactional execution (STE) instruction, which marks the beginning of a block of instructions to be executed transactionally. Upon encountering the STE instruction during execution of a program, the system commences transactional execution of the block of instructions following the STE instruction. Changes made during this transactional execution are not committed to the architectural state of the processor until the transactional execution successfully completes.

摘要： One embodiment of the present invention provides a system that selectively monitors load instructions to support transactional execution of a process, wherein changes made during the transactional execution are not committed to the architectural state of a processor until the transactional execution successfully completes. Upon encountering a load instruction during transactional execution of a block of instructions, the system determines whether the load instruction is a monitored load instruction or an unmonitored load instruction. If the load instruction is a monitored load instruction, the system performs the load operation, and load-marks a cache line associated with the load instruction to facilitate subsequent detection of an interfering data access to the cache line from another process. If the load instruction is an unmonitored load instruction, the system performs the load operation without load-marking the cache line.
摘要翻译：本发明的一个实施例提供了一种系统，其选择性地监视加载指令以支持进程的事务性执行，其中在事务执行期间进行的改变不被提交到处理器的体系结构状态，直到事务执行成功完成。在执行指令块的事务执行期间遇到加载指令时，系统确定加载指令是监视加载指令还是不受监控的加载指令。如果加载指令是被监视的加载指令，则系统执行加载操作，并加载标记与加载指令相关联的高速缓存行，以便随后检测到来自另一进程的高速缓存行的干扰数据访问。如果加载指令是不受监控的加载指令，则系统将执行加载操作，而不加载标记缓存行。

摘要： Mechanisms have been developed for providing great flexibility in processor instruction handling, sequencing and execution. In particular, it has been discovered that a configurable predecode mechanism can be employed to select, for respective instruction patterns, between fixed decode and programmable decode paths provided by a processor. In this way, a patchable and/or programmable decode mechanism can be efficiently provided. In some realizations, either (or both) predecode or (and) decode may be configured or reconfigured post-manufacture. In some realizations, either (or both) predecode or (and) decode may be configured at (or about) initialization. In some realizations, either (or both) predecode or (and) decode may be configured at run-time.

摘要： A technique recovers return address stack (RAS) content and restores alignment of a RAS top-of-stack (TOS) pointer for occurrences of mispredictions due to speculative operation, out-of-order instruction processing, and exception handling. In at least one embodiment of the invention, an apparatus includes a speculative execution processor pipeline, a first structure for maintaining return addresses relative to instruction flow at a first stage of the pipeline, at least a second structure for maintaining return addresses relative to instruction flow at a second stage of the pipeline. The second stage of the pipeline is deeper in the pipeline than the first stage. The apparatus includes circuitry operable to reproduce at least return addresses from the second structure to the first structure.

摘要： A method and apparatus for accelerating a software transactional memory (STM) system is described herein. Annotation field are associated with lines of a transactional memory. An annotation field associated with a line of the transaction memory is initialized to a first value upon starting a transaction. In response to encountering a read operation in the transaction, then annotation field is checked. If the annotation field includes a first value, the read is serviced from the line of the transaction memory without having to search an additional write space. A second and third value in the annotation field potentially indicates whether a read operation missed the transactional memory or a tentative value is stored in a write space. Additionally, an additional bit in the annotation field, may be utilized to indicate whether previous read operations have been logged, allowing for subsequent redundant read logging to be reduced.
摘要翻译：本文描述了用于加速软件事务存储器（STM）系统的方法和装置。注释字段与事务存储器的行相关联。与事务存储器的行相关联的注释字段在启动事务时被初始化为第一个值。响应于在事务中遇到读取操作，则检查注释字段。如果注释字段包含第一个值，则读取将从事务存储器的行提供服务，而不必搜索额外的写入空间。注释字段中的第二和第三个值潜在地指示读操作是否错过事务存储器或暂存值是否存储在写空间中。此外，注释字段中的另外一个位可以用于指示是否已经记录先前的读取操作，从而允许减少随后的冗余读取记录。
