Abstract: An embodiment features a method of generating test data. An application-level schema corresponding to a source relational database is received. The schema defines constraints comprising one or more of inter-field, inter-record, and inter-object constraints between related data in the source relational database. A random walk is performed on a graph of nodes representing data in the source relational database. At respective ones of the nodes, corresponding ones of the data in the source relational database are selected along a path ordered in accordance with the constraints defined in the schema. Synthetic test data is generated based on one or more statistical models of the data selected from the source relational database. Data values are generated for respective fields of an object defined in the schema, and data values are generated for records related to the object based on one or more of the constraints defined in the schema.

Abstract: In an example, a method includes selecting a unique identifier corresponding to a set of rules. At least one modified image is generated from a seed image using a processor by determining and applying an image attribute modification to the seed image according to at least one rule in the set of rules of the unique identifier. The modified image is placed in a predefined position according to at least one rule in the set of rules of the unique identifier.

Abstract: Systems, methods and devices according to this invention include a plurality of defined modification rules for modifying a sequence of packets that form an attack on an intrusion detection system. These modification rules include both rules that expand the number of packets and rules that reduce the number of packets. The reducing rules can be applied to a given attack instance to identify one or more root attack instances. The expanding rules can then be applied to each root attack instance to generate a corpus of modified attack instances. The modification rules can preserve the semantics of the attack, so that any modified attack instance generated from the given attack instance remains a true attack. To test an intrusion detection system, the corpus of modified attack instances can be used to determine whether an intrusion detection system detects every modified attack instance.

Abstract: A method for functional verification of a design for a parallel processing device includes receiving a sequence of single instructions from a dynamic test program generator, and assembling a plurality of the instructions from the sequence into an instruction word, in accordance with predetermined rules applicable to the parallel processing device. The instruction word is input to a simulator of the parallel processing device so as to determine a response of the device to the instruction word.

Abstract: A technique for improving the performance of binary tree operations involves defining an implicit binary tree structure in a memory array, and clustering of the nodes of the tree in memory in a cache-aware manner. The technique reduces memory latency by improved spatial locality of the binary tree data, and further improves cache performance through reduced size of the data objects resulting from elimination of pointers to other nodes of the tree.
