20080270838DISTRIBUTED, FAULT-TOLERANT AND HIGHLY AVAILABLE COMPUTING SYSTEM - A method and system for achieving highly available, fault-tolerant execution of components in a distributed computing system, without requiring the writer of these components to explicitly write code (such as entity beans or database transactions) to make component state persistent. It is achieved by converting the intrinsically non-deterministic behavior of the distributed system to a deterministic behavior, thus enabling state recovery to be achieved by advantageously efficient checkpoint-replay techniques. The method comprises: adapting the execution environment for enabling message communication amongst and between the components; automatically associating a deterministic timestamp in conjunction with a message to be communicated from a sender component to a receiver component during program execution, the timestamp representative of estimated time of arrival of the message at a receiver component. At a component, tracking state of that component during program execution, and periodically checkpointing the state in a local storage device. Upon failure of a component, the component state is restored by recovering a recent stored checkpoint and re-executing the events occurring since the last checkpoint. The system is deterministic by repeating the execution of the receiving component by processing the messages in the same order as their associated timestamp.10-30-2008

Each of The plurality of serial communication circuits contains a data buffer and serially transmits data stored in the data buffer to and from the target device while synchronized with the clock signal. Namely, the plurality of serial communication circuits communicate in parallel while operating synchronized with the same clock. The on-chip debug emulator can in this way be made utilizing a low-cost microcomputer not containing any parallel communication circuits.09-18-2008
20080222455Reporting diagnostic information for code of an application program interface - A technology for reporting diagnostic information for code of an application program interface is disclosed. In one method approach, diagnostic information for a line of code in a file associated with an application program interface is received. The diagnostic information includes a designation of the line of code. The diagnostic information is stored in a fixed sized buffer. Efficient use of memory is provided without requiring elimination of other diagnostic information previously stored in the fixed sized buffer.09-11-2008
20080222454PROGRAM TEST SYSTEM - An improved automated software testing system provides the ability to generate and reuse test cases over multiple platforms. Keywords and natural language are used in test case creation, simplifying the process for non-technical business users. Business users can write test cases without scripts. Test cases can be generated even before the application to be tested is available. Data substitution provides ability for test cases to adapt to changing data. Abstraction allows use of all third-party and custom software test tools to be incorporated. Persistent data handling allows capture of data generated during test execution for later use. Testing can be performed entirely automatically or can incorporate some manual interaction. Test results, screen captures of the system tested, along with environment and machine variables are saved in results logs for later review.09-11-2008
20080201613METHODS AND SYSTEMS FOR FIRST OCCURENCE DEBUGGING - An embodiment relates generally to an apparatus for debugging. The apparatus includes a memory configured to store data and an arithmetic logic unit configured to perform logical and arithmetic operations. The apparatus also includes a control unit configured to interface with the memory and arithmetic logic unit and to decode instructions. The control unit is configured to write a data state designated to be overwritten by a currently executing instruction to a buffer allocated in the memory in response to a trace debug flag being set.08-21-2008
20080201612Defect Resolution Methodology and Data Defects Quality/Risk Metric Model Extension - Methods, systems, and articles of manufacture for analyzing defects associated with a software development project. Descriptions of defects identified during the testing of a software product may be stored in a data structure. One or more of the defects may be identified as data defects. If data defects are determined to be the dominant class of defects in the data structure, the data defects may be analyzed to determine a cause for one or more data defects. For example, the focus areas affected by the defects, the trends over time of the defects, the particular types of the data defects, the stability of the system, etc. may be analyzed to determine a cause for the data defects. Therefore, corrective measures may be taken based on the identified cause of the one or more data defects.08-21-2008
20100287414EXCEPTION RAISED NOTIFICATION - An exception notification system is described herein that provides an early notification that a software exception has occurred before exception handling code has run. The exception notification system receives a registration request from program code to register a handler to receive an early notification when an exception occurs. When an exception occurs, the system raises an event that calls each registered handler. After the handler returns, the system performs normal exception handling, so that the early notification does not change existing exception-handling behavior. The exception notification system allows a program to inspect and log an exception before the program state has been modified by exception handling. The program code can capture detailed information about the cause of the exception to enable further offline analysis. Thus, the exception notification system allows developers to improve their programs by receiving more information about unexpected conditions in the program code.11-11-2010
20100318854SYSTEM AND METHOD FOR CHECKING FIRMWARE DEFINITION FILE - A system and a method for checking a firmware definition file are provided. The system includes a software control side and a plurality of hardware signal sides. The software control side has a firmware definition file, and generates a plurality of simulating signals in accordance with the firmware definition file. The hardware signal sides receive the simulating signals respectively so as to generate a plurality of feedback signals fed to the software control side. The software control side establishes an event log in accordance with the feedback signals, and uses the event log to check if the firmware definition file is correct.12-16-2010
