20080270590 | DYNAMIC CONFIGURATION AND SELF-TUNING OF INTER-NODAL COMMUNICATION RESOURCES IN A DATABASE MANAGEMENT SYSTEM - A database management system in which a plurality of nodes form a database instance, each node including a communication manager for dynamically configuring inter-nodal communication resources. The communication manager receives communication resource allocation requests from clients or a self-tuning algorithm. A resource self-tuning mechanism allocates or de-allocates memory blocks used for communication resource elements dynamically in real time without cycling the instance. Memory blocks are de-allocated asynchronously by placing associated communication resource elements in quarantine until all communication resource elements associated with the memory block are quarantined. | 10-30-2008 |
20130226902 | SYSTEM AND PROGRAM FOR JOINING SOURCE TABLE ROWS WITH TARGET TABLE ROWS - A data processing system, and an article of manufacturing, join rows associated with a source table column with rows associated with a target table column. A source node and a target node contain the source and target tables, respectively. A reduced representation of selected rows associated with the source table column is generated, as is a representation of the target table column. A filtering module filters the generated reduced representation of selected rows associated with the source table column through the generated representation of the target table column, the filtered generated reduced representation of selected rows identifying source table rows that do not have to be joined with the target table. The rows associated with the source table column minus the filtered generated reduced representation of selected rows are joined to the rows associated with the target table column. | 08-29-2013 |

20090157995 | DYNAMIC MEMORY MANAGEMENT IN AN RDMA CONTEXT - A method for dynamically managing memory to support one or more processes executing in a remote direct memory access (RDMA) environment is provided. The method includes inserting a descriptor in a shared descriptor table, the descriptor corresponding to a block of memory allocated to a heap by an operating system. The method further includes, in response to allocating a portion of the block of memory from the heap to a process, determining whether the process has an existing registration with an application program interface for the block of memory. If the process has no existing registration, registering the process the process is registered with the application program interface and a registration corresponding to the block of memory is stored in a private registration table of the process. Additionally, the method includes, in response to the process releasing the allocated portion of the block of memory to the operating system, de-registering with the application program interface and removing the registration from the registration table. When the block of memory is released to the operating system, other registrations corresponding to the block of memory in other private registration tables of other processes remain in the other registration tables. | 06-18-2009 |

20160138282 | Multi-function bull float with modified edge or edges. - A bull float for leveling and finishing concrete made from two different materials is disclosed. In one embodiment, the main wooden base has an insert made from fiberglass. As the bull float is pushed forward, the pole is angled such that the wooden back edge levels and smooths the concrete, then on the return stroke the pole is raised such that the fiberglass front edge finishes the concrete as the bull float is swept back to the concrete worker. This bull float performs the tasks currently requiring three separate bull floats, thereby saving the worker from having to replace and clean two or three separate bull floats. As concrete sets up quickly, the time savings obtained through using just a single bull float results in superior concrete slabs with less effort required of the concrete worker and more time to work the concrete. | 05-19-2016 |
