摘要： A method and system for achieving highly available, fault-tolerant execution of components in a distributed computing system, without requiring the writer of these components to explicitly write code (such as entity beans or database transactions) to make component state persistent. It is achieved by converting the intrinsically non-deterministic behavior of the distributed system to a deterministic behavior, thus enabling state recovery to be achieved by advantageously efficient checkpoint-replay techniques. The method comprises: adapting the execution environment for enabling message communication amongst and between the components; automatically associating a deterministic timestamp in conjunction with a message to be communicated from a sender component to a receiver component during program execution, the timestamp representative of estimated time of arrival of the message at a receiver component. At a component, tracking state of that component during program execution, and periodically checkpointing the state in a local storage device. Upon failure of a component, the component state is restored by recovering a recent stored checkpoint and re-executing the events occurring since the last checkpoint. The system is deterministic by repeating the execution of the receiving component by processing the messages in the same order as their associated timestamp.
摘要翻译：一种用于在分布式计算系统中实现高可用性，容错执行组件的方法和系统，而不需要这些组件的写入程序来明确地编写代码（例如实体bean或数据库事务）以使组件状态持续存在。通过将分布式系统的本质非确定性行为转换为确定性行为来实现，从而通过有利的高效检查点重放技术实现状态恢复。该方法包括：使执行环境适应于在组件之间和之间启用消息通信; 将确定性时间戳与在程序执行期间从发送方组件传送到接收方组件的消息相结合，该时间戳代表消息在接收器组件处的估计到达时间。在组件中，在程序执行期间跟踪该组件的状态，并周期性地检查本地存储设备中的状态。在组件发生故障时，通过恢复最近存储的检查点并重新执行自上次检查点以来发生的事件来恢复组件状态。通过以与其相关联的时间戳相同的顺序处理消息来重复接收组件的执行，该系统是确定性的。

摘要： A method and system for achieving time-awareness in the highly available, fault-tolerant execution of components in a distributed computing system, without requiring the writer of these components to explicitly write code (such as entity beans or database transactions) to make component state persistent. It is achieved by converting the intrinsically non-deterministic behavior of the distributed system to a deterministic behavior, thus enabling state recovery to be achieved by advantageously efficient checkpoint-replay techniques. The system is deterministic by repeating the execution of the receiving component by processing the messages in the same order as their associated timestamps and time-aware by allowing adjustment of message execution based on time.

摘要： Techniques for viral promotion of content are described. According to various embodiments, a user request to promote a content item to a member base of an online social network service is received. For example, the request to promote the content item may be received from an advertiser or marketer in conjunction with a request to receive a predetermined number of social activity signals (e.g., likes, shares, follows, comments, etc.) in association with the content item (e.g., as part of an advertising or marketing campaign). Viral promotion seed user definition information specifying one or more definitions of a viral promotion seed user is then accessed. Thereafter, a particular member of the online social network service is classified as the viral promotion seed user, based on the viral promotion seed user definition information. The content item is then selectively promoted to the viral promotion seed user.
