Abstract: Technologies for discontinuous execution include a compiler computing device and one or more target computing devices. The compiler computing device converts a computer program into a sequence of atomic transactions and coalesces the transactions to generate additional sequences of transactions. The compiler computing device generates an executable program including two or more sequences of transactions having different granularity. A target computing device selects an active sequence of transactions from the executable program based on the granularity of the sequence and a confidence level. The confidence level is indicative of available energy produced by an energy harvesting unit of the target computing device. The target computing device increases the confidence level in response to successfully committing transactions from the active sequence of transactions into non-volatile memory. In response to a power failure, the target computing device resets the confidence level and resumes executing the transactions. Other embodiments are described and claimed.

Abstract: In accordance with an embodiment, described herein is a system and method for transaction recovery in a multitenant application server environment. At least one resource manager associated with a partition can be designated as a determiner resource for that partition only, in order to support eliminating transaction logs (TLOG) in processing a two-phase commit transaction. A transaction manager can prepare all other resource managers in the mid-tier transactional system before the determiner resource. Furthermore, the transaction manager can rely on the list of outstanding transactions to be committed that is provided by the determiner resource for recovering the transaction. The transaction manager can commit an in-doubt transaction returned from a resource manager that matches the list of in-doubt transactions returned from the determiner resource. Otherwise, the transaction manager can roll back the in-doubt transaction.

Abstract translation: 根据一个实施例，这里描述了一种用于多租户应用服务器环境中的事务恢复的系统和方法。 与分区相关联的至少一个资源管理器可以仅被指定为该分区的确定器资源，以便在处理两阶段提交事务时支持消除事务日志（TLOG）。 事务管理器可以在确定器资源之前准备中间层事务系统中的所有其他资源管理器。 此外，事务管理器可以依赖由确定器资源为恢复事务而提供的未完成事务的列表。 事务管理器可以提交从资源管理器返回的与从确定器资源返回的无疑事务列表相匹配的无疑事务。 否则，事务管理器可以回滚不确定事务。

Abstract: Task specific diagnostic controls are provided to facilitate the debugging of certain types of abort conditions. The diagnostic controls may be set to cause transactions to be selectively aborted, allowing a transaction to drive its abort handler routine for testing purposes. The controls include, for instance, a transaction diagnostic scope and a transaction diagnostic control. The transaction diagnostic scope indicates when the transaction diagnostic control is to be applied, and the transaction diagnostic control indicates whether transactions are to selectively aborted.

Abstract: Embodiments of the invention relate to implementing run-time instrumentation sampling in transactional-execution mode. An aspect of the invention includes a method for implementing run-time instrumentation sampling in transactional-execution mode. The method includes determining, by a processor, that the processor is configured to execute instructions of an instruction stream in a transactional-execution mode, the instructions defining a transaction. The method also includes interlocking completion of storage operations of the instructions to prevent instruction-directed storage until completion of the transaction. The method further includes recognizing a sample point during execution of the instructions while in the transactional-execution mode. The method additionally includes run-time-instrumentation-directed storing, upon successful completion of the transaction, run-time instrumentation information obtained at the sample point.

Abstract: An adaptive mechanism is provided that learns the response time characteristics of a workload by measuring the response times of end user transactions, classifies response times into buckets, and dynamically adjusts the response time distribution as response time characteristics of the workload change. The adaptive mechanism maintains the actual distribution across changes and, thus, helps the end user to understand changes of workload behavior that take place over a longer period of time. The mechanism is stable enough to suppress spikes and returns a constant view of workload behavior, which is required for long term performance analysis and capacity planning. The mechanism distinguishes between an initial learning phase of establishing the distribution and one or multiple reaction periods. The reaction periods can be for example a fast reaction period for strong fluctuations of the workload behavior and a slow reaction period for small deviations.

Abstract translation: 提供了一种自适应机制，通过测量最终用户事务的响应时间，将响应时间分类为桶，并动态调整响应时间分布作为工作负载变化的响应时间特征，来学习工作负载的响应时间特征。 自适应机制保持实际的分布在变化之间，从而有助于最终用户了解更长时间内发生的工作负载行为的变化。 该机制足够稳定，可以抑制尖峰，并返回持续的工作负载行为视图，这是长期性能分析和容量规划所必需的。 该机制区分建立分布的初始学习阶段与一个或多个反应周期。 反应周期可以是例如对于工作负载行为的强烈波动和对于小偏差的缓慢的反应时间的快速反应时段。

Abstract: A probe within a Network-on-Chip (NoC) that can calculate a histogram of transaction data is disclosed. Some such histograms are cycles per number of pending transactions, transactions per latency, and transactions per request delay. The number of pending transactions can be measured by a register that is incremented at the start and decremented at the end of each transaction. Latencies can be measured by timers that are allocated and initialized at the start and read at the end of each transaction. Multiple counters can be used for multiple pending transactions. Multiple banks of counters can be used so that multiple transaction interfaces can complete transactions and perform histogram bin threshold comparisons simultaneously. The thresholds separating histogram bins can be programmable.

Abstract: A Java enterprise resource management (JERM) system and method are provided that allow both timing metrics and call metrics to be monitored and gathered in real-time, and which can cause appropriate actions to be taken in real-time. The JERM system provides a level of granularity with respect to the monitoring of methods triggered during a transaction that is equivalent to or better than that which is currently provided in the aforementioned known call-analysis resource management systems. In addition, the JERM system also provides information associated with the timing of hops that occur between servers, and between and within applications, during a transaction. Because all of this information is obtained in real-time, the JERM system is able to respond in real-time to cause resources to be scaled in or scaled out in a way that provides improved efficiency and productivity, and that enables the enterprise to quickly recover from resource failures.

Abstract: An efficient, cycle-accurate processor execution simulator models a target processor by executing a program execution image comprising instructions having run-time dependencies resolved by execution on an existing processor compatible with the target processor. The instructions may have been executed upon a processor in an I/O environment too complex to model. In one embodiment, the simulator executes instructions that were directly executed on a processor. In another embodiment, a markup engine alters a compiled program image, with reference to instructions executed on a processor, to remove run-time dependencies. The marked up program image is then executed by the simulator. The processor execution simulator includes an update engine operative to cycle-accurately simulate instruction execution, and a communication engine operative to model each communication bus of the target processor.

Abstract: A method includes storing a first transaction entry to a first software configurable storage location, storing a second transaction entry to a second software configurable storage location, determining that a first transaction indicated by the first transaction entry has occurred (44, 46), determining that a second transaction indicated by the second transaction entry has occurred (44, 46) subsequent to the first transaction, and, in response to determining that the first transaction occurred and the second transaction occurred, storing at least one transaction attribute captured during at least one clock cycle subsequent to the second transaction (68). The first and second software configurable storage locations may be located in a trace buffer (26), where the at least one transaction attribute is stored to the trace buffer and overwrites the first and second transaction attributes. Each transaction entry may include a dead cycle field, a consecutive transaction requirement field, and a last entry field.
