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 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.
摘要翻译：本发明的实施例使得能够跨高度并行系统的多个计算节点运行的应用程序选择性地将对象从一个节点迁移到另一个节点。例如，当对象变得太大时，包含对象的节点可能会将对象迁移到另一个节点，从而释放内存空间。是否迁移大对象可以取决于应用程序使用对象的频率。因为这样一个对象使用的内存被应用程序的其他用途所释放，所以整体应用程序的性能可能会得到改善。在具有数千个计算节点的大型并行系统上，即使相对较小的应用程序性能改进，单个计算节点可能会被放大多次，从而在整体应用程序性能方面有显着改进。

摘要： An apparatus and method for a database query optimizer utilizes a combining network to optimize a portion of a query in a parallel computer system with multiple nodes. The efficiency of the parallel computer system is increased by offloading collective operations on node data to the global combining network. The global combining network performs collective operations such as minimum, maximum, sum, and logical functions such as OR and XOR.

摘要： A process is disclosed for identifying and recovering from resource leaks on compute nodes of a parallel computing system. A resource monitor stores information about system resources available on a compute node in a clean state. After the compute node runs a job, the resource monitor compares the current resource availability to the clean state. If a resource leak is found, the resource monitor contacts a global resource manger to remove the resource leak.

摘要： A process on a highly distributed parallel computing system is disclosed. When a first compute node in a first pool is ready to hand-off a task to second pool for further processing, the first compute node may first determine whether a node is available in the second pool. If no node is available from the second pool, then the first compute node may begin performing a primary task assigned to the second pool of nodes, up to the point where a service available exclusively to the nodes of the second pool is required. In the interim, however, one of the nodes of the second pool may become available. Alternatively, an application program running on a compute node may be configured with an exception handling routine that catches exceptions and migrates the application to a compute node where a necessary service is available, as such exceptions occur.
