摘要： To determine files associated with one or more workflows, a trace of accesses of files in at least one server is received. The files are grouped into at least one set of files, where the files in the set are accessed together more than a predetermined number of times in the trace. Files associated with the particular workflow are identified based on the at least one set.

摘要： A remote procedure call chain is provided that replaces multiple consecutive remote procedure calls to multiple servers from a client by allowing a client to specify multiple functions to be performed consecutively at multiple servers in a single remote procedure call chain. The remote procedure call chain is executed by a sequence of multiple servers. Each server executes a service function and a chaining function of the remote procedure call chain. The chaining function uses the state of the remote procedure call chain in the sequence of servers to determine the next server to receive the remote procedure call chain, and the service function to be executed by that server. After the last service function is performed, the last server in the sequence of servers sends the results of the executed service functions to the client that originated the remote procedure call chain.
摘要翻译：提供了一个远程过程调用链，通过允许客户端指定要在单个远程过程调用链中的多个服务器上连续执行的多个函数，将多个连续远程过程调用替换为多个服务器。远程过程调用链由多个服务器的序列执行。每个服务器执行远程过程调用链的服务功能和链接功能。链接功能使用服务器序列中的远程过程调用链的状态来确定接收远程过程调用链的下一个服务器以及由该服务器执行的服务功能。在执行最后一个服务功能之后，服务器序列中的最后一个服务器将执行的服务功能的结果发送给发起远程过程调用链的客户端。

摘要： Embodiments of the present invention pertain to improving recoverability of a dataset associated with a multi-tier storage system. According to one embodiment, updates to a dataset are stored in first storage. The dataset and a point-in-time copy of the dataset reside on second storage, and the first storage provides higher reliability than the second storage. The dataset is restored using at least a subset of the stored updates in combination with the point-in-time copy in the event that the dataset is lost.
摘要翻译：本发明的实施例涉及提高与多层存储系统相关联的数据集的可恢复性。根据一个实施例，数据集的更新被存储在第一存储器中。数据集和数据集的时间点副本驻留在第二个存储上，而第一个存储提供比第二个存储更高的可靠性。在数据集丢失的情况下，使用至少存储的更新的一个子集与时间点副本组合恢复数据集。

摘要： Preventing replay attacks on servers. At least one Bloom filter may be set up in a server for tracking requests received from clients. Identifying data may be generated for each request. The identifying data may be checked against the Bloom filter array. If a match is found, the message may be a replay and may be rejected. If a match is not found, the request identifying data may be added to the Bloom filter and the request may be processed.

摘要： The Heartbeat Failure Detector of the present invention, is a new, simple method and device that has several identical modules, and each module is attached to a processor in the system. Roughly speaking, the module of a processor x maintains a heartbeat counter for every other process. For each process y, the counter of y at x (called the heartbeat of y at x) periodically increases while y is alive and in the same network partition, and the counter stops increasing after y crashes or becomes partitioned away. Using such a device, x can solve the communication problem above by resending m only if the heartbeat of y at x increases. Note that if y is crashed (or partitioned away from x), its heartbeat at x stops almost immediately, and so x will also immediately stop sending copies of m to y.
摘要翻译：本发明的心跳故障检测器是一种新的，简单的方法和装置，其具有几个相同的模块，并且每个模块附接到系统中的处理器。大致来说，处理器x的模块为每个其他进程维护一个心跳计数器。对于每个进程y，x处的y的计数器（在x处称为y的心跳）在y活着的同时在相同的网络分区中周期性地增加，并且在y崩溃或被分割之后计数器停止增加。使用这样的设备，x只有在y的心跳增加时才能通过重新发送m来解决上述通信问题。请注意，如果y崩溃（或远离x），则其心跳几乎立即停止，因此x也将立即停止将m的副本发送给y。

摘要： A cloud statistics server generates statistics for a cloud service based on an identified data item and an identified operation. The cloud service may include various computing nodes and storage nodes. The cloud statistics may include expected completion times for the identified operation and the identified data item with respect to each of the computing nodes. A computing node may be selected to execute the identified operation based on the expected completion times. The generated statistics may be generated by the cloud statistics server using a network topology associated with the data item that is based on the latencies or expected transfer times between the various storage nodes and computing nodes, and a replication strategy used by the cloud service. The topology may be implemented as a directed graph with edge weights corresponding to expected transfer times between each node.
