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.

摘要： A method and apparatus for fault recovery of on a parallel computer system from a soft failure without ending an executing job on a partition of nodes. In preferred embodiments a failed hardware recovery mechanism on a service node uses a heartbeat monitor to determine when a node failure occurs. Where possible, the failed node is reset and re-loaded with software without ending the software job being executed by the partition containing the failed node.

摘要： The disclosure herein provides data security on a parallel computer system using virtual private networks connecting the nodes of the system. A mechanism sets up access control data in the nodes that describes a number of security classes. Each security class is associated with a virtual network. Each user on the system is associated with one of the security classes. Each database object to be protected is given an attribute of a security class. Database objects are loaded into the system nodes that match the security class of the database object. When a query executes on the system, the query is sent to a particular class or set of classes such that the query is only seen by those nodes that are authorized by the equivalent security class. In this way, the network is used to isolate data from users that do not have proper authorization to access the data.

摘要： Methods, systems, and products are disclosed for executing a distributed Java application on a plurality of compute nodes. The Java application includes a plurality of jobs distributed among the plurality of compute nodes.
