Abstract: A method for allocating memory in a computer system includes allocating a block of memory from an operating system, dividing the block of memory into frames, and dividing each of the frames into instances such that each of the instances is operable to store data. In addition, a software application using application-level memory management includes an application-level memory manager operable to allocate a block of memory to store data elements with the block of memory divided into frames and each frame divided into instances, and application code operable to store data elements in instances of a block of memory allocated by the application-level memory manager.

Abstract: Techniques are described for organizing data in a fast query system. Data structures are provided, where each of the data structures forms part of at least one traversable structure and represents at least a first value of a first attribute of a data record forming a body of data records. Each of at least some of the data structures are associated with at least one other data structure forming part of another traversable structure, where the other data structure represents at least a second value of a second attribute of the data record.

Abstract: Methods and systems for assigning objects to processing units of a cluster of processing units are provided. In one implementation, the objects to be assigned may be sorted by size, which provides a sequence of objects. Starting with the first processing unit, objects may then be assigned in sequential order. This way the loading of the processing units may be balanced.

Abstract: Techniques are described for performing logical operations, where the techniques generally involve the use of dynamic flags used as markers to build a result set in response to a search query. The dynamic flags within a result set may be guide elements linked to one another, and to their respective data records and attributes, via pointers. In this case, the groups of guide elements forming result sets may each also be linked to one another via pointers, and may each be associated with a counter for counting a number of guide elements within a corresponding result set. The dynamic flags also may be individual bits within a bitmap, where the bitmap is linked to a particular result set identifier via a pointer, and the individual bitmaps are linked to their corresponding data record(s) via a relative addressing scheme. In this case, a counter also may be used to determine a number of hits within a result set (bitmap), before, during, and after a particular logical operation.

Abstract: The present invention relates to a method of assigning objects to processing units of a cluster of processing units, each one of the objects having an object size and an object load, each one of the processing units having a storage capacity and a load capacity, the method comprising the steps of: a) calculating an index based on object size and object load for each one of the objects, b) sorting of the objects by index to provide a sequence of objects; c) for each processing unit of the cluster: assigning of one or more of the objects to the processing unit in sequential order until a remaining storage capacity and/or a remaining load capacity of the processing unit is too small for consecutive objects of the sequence; deleting of the objects that are assigned to the processing unit from the sequence.

Abstract: Method and computer system for software tuning. A computer system stores variables (210) for storing at least one threshold value for at least one parameter (P1) influencing the performance of a software application (200) with regards to a specific task. A threshold evaluator (220) compares (430) the at least one threshold value to at least one corresponding current value allowing the software application (200) to select (440) an algorithm (A1) from a plurality of algorithms (A1 to AN) for performing the task in accordance with the result of comparison.

Abstract: Method and computer system for logically evaluating a Boolean expression used in a query statement to optimize the query. The Boolean expression refers to an attribute and includes a plurality of conditions. The Boolean expression is received (410) and decomposed (420) into the plurality of conditions. For each condition at least one condition value referring to the attribute is extracted (421) from the condition. The at least one condition value is then inserted (422) into a condition value list in sorted order. A relationship vector of the at least one condition value is initialized (423). Then the relationship vectors of the at least one condition value and of each further condition value that is in the condition list and that is in the value range of the condition are adjusted (424). After having processed all conditions the Boolean expression may be reducing (430) according to each relationship vector.

Abstract: A graphical user interface displays an ordered series of items. Each of the items has an index value indicating a position of the item within the series. The graphical user interface includes a scroll bar to scroll through the first ordered series. Items with index values that are outside of a first threshold range around a reference index value corresponding to a position of a slider of the scroll bar are displayed to have an appearance that is different from items having index values inside the first threshold range.

Abstract: If search result records from a database search have an attribute that at least two of the search result records share, but which was not used in the query, then categories are created to correspond to values of the shared attribute. The categories can be displayed in a user-friendly manner, as can a list of the search result records associated with a selected category.

Abstract: A method and system for displaying context-sensitive columns in a table of a graphical user interface (GUI) are provided for software running on a processor and being displayed to a user. The context-sensitive columns allow additional information to be displayed in a table on a window of a graphical user interface only when the columns contain information that is relevant. In this manner, the context-sensitive columns are not displayed and do not take up space on the display if they do not contain relevant information thereby freeing the display from unnecessary clutter and possibly reducing the need for horizontal scrolling in a table to view all the columns of data contained therein. For example, an error column may be displayed according to this embodiment only if errors have occurred and are included in one of the cells of the column.

Abstract: A method and system are provided for implementing enhanced buttons in graphical user interface of a software application running on computer system. The enhanced buttons allow additional options to be presented to the user in a context-sensitive manner in the same graphical user interface screen that the user is interacting with. The enhanced buttons are context-sensitive buttons that appear on a graphical user interface window as a result of an initiating action or operation selected from the screen. The initiating operation may be linked to a field, button, or other graphical element or object on the screen and the context-sensitive buttons are associated with this linked graphical element. The context-sensitive buttons may be displayed on the graphical user interface screen in relation to the associated graphical element.

Abstract: In a system and method for grouping data, a processor may, with reference to metadata identifying relationships between sets of data to be displayed in columns of a table, generate a display template from the identified relationships, the template defining that related columns of data are presented adjacent to each other in groups and defining which types of graphical demarcations to display, may search among records corresponding to rows of the table to be displayed for records that satisfy a search criterion, and may display a table according to the display template, rows of the table arranged to display the records that satisfy the search criteria in a group separate from the other records.

Abstract: A system and method for providing information about an operation's applicability to an item. A processor may provide a list of selectable items in a display area and may provide for each of the listed items, in response to receiving a command to perform an operation on selected items of the display area, an indication of a reason for the operation's applicability or inapplicability to the item.

Abstract: A data processing system has a program module for determining a re-distribution of objects, such as database tables, over processing units of a cluster of processing units, such as in a blade computing environment.
