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: Methods and computer systems are provided for reducing the runtime of a material requirements planning run. In one embodiment, a computer system loads a plurality of bills of materials into a data structure. The computer system may analyze parent-child relationships between components of the plurality of bills of materials in the data structure and set for each component in the data structure a counter value that indicates the number of parent components for each component. The counter value of a specific child component may be decremented when the planning of a parent component of the specific child component is completed. The computer system may then proceed with the planning of the specific child component if the associated counter value indicates that the planning of all parent components of the specific child component is completed.

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 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.
