摘要： Techniques are provided for using an intermediate cache to provide some of the items involved in a scan operation, while other items involved in the scan operation are provided from primary storage. Techniques are also provided for determining whether to service an I/O request for an item with a copy of the item that resides in the intermediate cache based on factors such as a) an identity of the user for whom the I/O request was submitted, b) an identity of a service that submitted the I/O request, c) an indication of a consumer group to which the I/O request maps, d) whether the I/O request is associated with an offloaded filter provided by the database server to the storage system, or e) whether the intermediate cache is overloaded. Techniques are also provided for determining whether to store items in an intermediate cache in response to the items being retrieved, based on logical characteristics associated with the requests that retrieve the items.

摘要： Automated management of shared I/O resources involves use of a policy engine for implementing I/O scheduling group I/O policies. The I/O policies are used for determining whether corresponding I/O requests should be issued to a shared storage system immediately or should be delayed via corresponding policy-based queues. In the context of database systems, a database administrator can specify policies regarding how I/O resources should be used and the database system itself enforces the policies, rather than requiring the database administrator enforce the I/O usage of the database and of the individual users.

摘要： A routing process for a single-instruction-multiple-data (SIMD) multi-level hierarchical network of nodes, which are arranged in clusters and interconnected by dual, unidirectional channels, are used to send data packets including routing address information during a succession of routing cycles from transmitting ones to receiving ones of a large number of parallel processors (e.g., 4096 processors arranged in a hierarchy of 8 cabinets, each of which contains a cluster of 8 circuit boards, with each circuit board containing a cluster of 64 processors). Each of the nodes includes a storage buffer having a capacity equal to a given number which is one more than the total number of channels terminating at that node. This routing process guarantees prevention of deadlock between levels and buffer overflow, and offers high-speed, low-cost interprocessor communication for SIMD computers.
摘要翻译：用于单个指令多数据（SIMD）多级分层网络的路由过程被布置成群集并通过双向单向信道互连，用于在一系列连续的过程中发送包括路由地址信息的数据分组将多个并行处理器（例如，布置在8个机柜的层级中的4096个处理器（每个包含8个电路板的集群，每个电路板包含64个处理器的集群）的发送的路由循环）。每个节点包括具有等于给定数量的容量的存储缓冲器，其比在该节点终止的信道的总数量多一个。此路由过程保证防止级别与缓冲区溢出之间的死锁，并为SIMD计算机提供高速，低成本的处理器间通信。
