    摘要： A database loader loads data to an in-memory database across multiple nodes in a parallel computing system. The database loader uses SQL flags, historical information gained from monitoring prior query execution times and patterns, and node and network configuration to determine how to effectively cluster data attributes across multiple nodes. The database loader may also allow a system administrator to force placement of database structures in particular nodes.

    摘要： A method, apparatus, and program product manage scheduling of a plurality of jobs in a parallel computing system of the type that includes a plurality of computing nodes and is disposed in a data center. The plurality of jobs are scheduled for execution on a group of computing nodes from the plurality of computing nodes based on the physical locations of the plurality of computing nodes in the data center. The group of computing nodes is further selected so as to distribute at least one of a heat load and an energy load within the data center. The plurality of jobs may be additionally scheduled based upon an estimated processing requirement for each job of the plurality of jobs.

    摘要： A method and apparatus performs peer-to-peer file transfers on a High Performance Computing (HPC) cluster such as a Beowulf cluster. A peer-to-peer file tracker (PPFT) allows operating system, application and data files to be moved from a pre-loaded node to another node of the HPC cluster. A peer-to-peer (PTP) client is loaded into the nodes to facilitate PTP file transfers to reduce loading on networks, network switches and file servers to reduce the time needed to load the nodes with these files to increase overall efficiency of the multi-node computing system. The selection of the nodes participating in file transfers can be based on network topology, network utilization, job status and predicted network/computer utilization. This selection can be dynamic, changing during the file transfers as resource conditions change. The policies used to choose resources can be configured by an administrator.

    摘要： I/O nodes are dynamically distributed on a multi-node computing system. An I/O configuration mechanism located in the service node of a multi-node computer system controls the distribution of the I/O nodes. The I/O configuration mechanism uses job information located in a job record to initially configure the I/O node distribution. The I/O configuration mechanism further monitors the I/O performance of the executing job to then dynamically adjusts the I/O node distribution based on the I/O performance of the executing job.

    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.
