摘要： Embodiments of the invention enable application programs running across multiple compute nodes of a highly-parallel system to selectively migrate objects from one node to another. For example, when an object becomes too large, a node containing the object may migrate the object to another node, thereby freeing memory space. Whether a large object is migrated can be dependent on how frequently the object is used by the application. Because the memory used by such an object is freed for other uses by the application, overall application performance may be improved. On large parallel systems with thousands of compute nodes, even relatively small improvements in application performance an individual compute node may be magnified many times, resulting in dramatic improvements in overall application performance.

摘要： In a networked computer system that includes multiple nodes and multiple networks interconnecting the nodes, a database query optimizer takes network choice into consideration when optimizing a query. The query optimizer logs historical information for queries that includes network information. A network monitor determines network characteristics of the multiple networks. The query optimizer then selects a network for a query based on the network characteristics, and optionally based on the historical information as well. The result is a query optimizer that takes network choice into consideration, thereby providing a query that is optimized according to the characteristics of the networks.

摘要： Embodiments of the invention enable a database spread over multiple nodes to allow each node to have different indexes over the data in tables, depending on how each node would benefit (or not benefit) from having the index(es). When a database table is spread across the nodes of a multi-node or distributed system, each node may maintain only the portion of the index relevant to that node, if doing so would improve the performance of query processing operations on that node. Further, the database may periodically redistributed across the compute nodes based on index performance. Doing so allows the database system to intelligently trade off between consuming space for the index on a node and the usefulness of having an index on that node.
摘要翻译：本发明的实施例使得数据库能够跨越多个节点进行扩展，以允许每个节点相对于表中的数据具有不同的索引，具体取决于每个节点如何从获得索引而获益（或不受益）。当数据库表分布在多节点或分布式系统的节点上时，每个节点只能维护与该节点相关的索引部分，如果这样做可以提高该节点上的查询处理操作的性能。此外，数据库可以基于索引性能周期性地重新分布在计算节点上。这样做允许数据库系统在节点上的索引的消耗空间和在该节点上具有索引的有用性之间进行智能折中。

摘要： Techniques are disclosed for reducing the number of two-phase commits required to perform atomic transactions in a multi-node system. By monitoring atomic operations that require two-phase commit protocols, a system may identify when it would be beneficial to consolidate data onto single (or at least fewer) compute node(s). In doing so, a less compute intensive commit protocol, such as a one-phase commit protocol may be used. Moreover, in situations where data consolidation is not available, the data may be migrated to compute nodes having a closer proximity. Thus, in such cases, network response times for two-phase commits required for an atomic operation may be reduced, thereby increasing the performance of a multi-node system.
摘要翻译：公开了用于减少在多节点系统中执行原子事务所需的两阶段提交的数量的技术。通过监视需要两阶段提交协议的原子操作，系统可以识别何时将数据合并到单个（或至少较少的）计算节点是有益的。在这样做时，可以使用较少的计算密集型提交协议，例如单阶段提交协议。此外，在数据合并不可用的情况下，可将数据迁移到具有更靠近的计算节点。因此，在这种情况下，可以减少原子操作所需的两阶段提交的网络响应时间，从而增加多节点系统的性能。

摘要： Embodiments of the invention provide techniques that improve resource management on a massively parallel computing system having a plurality of hybrid compute nodes. For example, a job scheduler may be provided which determines a library to link to an application based on system and user requirements. In one embodiment, the libraries may provide optimizations for job execution time, and also provide optimizations directed towards a specific processor architecture. Once the library is determined, the job scheduler may configure the environment of the application so that the application links with the optimized library during run-time. Doing so may improve overall system performance of the massively parallel computing system.
