  • Publication number: 20090006621
    Abstract: A system and method detects communication error among multiple nodes in a concurrent computing environment. One or more barrier synchronization points/checkpoints or regions are used to check for a communication mismatch. The barrier synchronization point(s)/checkpoint(s) can be placed anywhere in the concurrent computing program. Once a node reaches a barrier synchronization point/checkpoint, it is not allowed to communicate with another node regarding data that is needed to execute the concurrent computing program, even if the other node has not reached the barrier synchronization point/checkpoint. Regions can also, or alternatively, be used to detect a communication mismatch instead of barrier synchronization points/checkpoints. A concurrent program on each node is separated into one or more regions. Two nodes communicate with each other when their regions are compatible. If their regions are not compatible, a communication mismatch occurs.

  • Publication number: 20090002371
    Abstract: A method and system are provided for generating code from a graphical model in a graphical modeling environment. The graphical model includes at least one signal having a data size, a data dimensionality, or both that can vary from a first time instance to a second time instance as the model executes. The size and dimensionality of the signal can vary without the use of a graphically rendered connection to convey the size and dimension information to a block associated with the signal.

  • Publication number: 20090006067
    Abstract: The present invention provides a method a system for facilitating enhanced processing of state diagrams in a state diagram environment. The method may include top-down processing a current state in a state diagram environment; determining whether processing of the current state results in an exception event; and passing the exception event to a superstate that includes the current state when it is determined that the current state results in an exception event. The superstate may be made the current state and it may be determined whether the current state can handle the exception event. When it is determined that the current state cannot handle the exception event, it may be determined whether the current state has a second superstate that includes the current state. An error event may be output from the state diagram environment when it is determined that the current state does not have a second superstate.

  • Patent number: 7464373
    Abstract: A system and method of exposing debugging information in a graphical modeling and execution environment is disclosed. The present invention allows a user to view debugging information in the same window as the graphical view of the model being executed. Debugging data is associated with relevant components of the model displayed in the graphical view. A separate execution list view shows the methods called during the execution of the block diagram in the current time step up until the current point in execution. User-set breakpoints and conditional breakpoints may be set in both the model view and the execution list view. Values may be obtained for all of the displayed methods. The debugging tool may be implemented by using it in conjunction with a graphical modeling and execution environment, such as a block diagram environment or state diagram environment.

  • Patent number: 7460984
    Abstract: Methods and systems for automatically reporting delay incurred in a model is disclosed. The delay may be incurred in a part or in an entire portion of the model. Delay incurred in each component of the model is determined and reported to users before executing the model. The delay of each component of the model may be determined based on intrinsic information of the component. If the intrinsic information of the component does not provide information on the delay of the component, the component may be simulated to determine the delay of the components. The model may be automatically compensated for the delay. The delay is reported prior to the execution of the model, and compensated for without executing the model.

  • Patent number: 7433808
    Abstract: In an embodiment, a computer-implemented method for modeling a system using a finite state machine representation is presented. An event-driven temporal logic operator may be associated with a first, active state in the finite state machine representation. A value of the temporal logic operator may be determined by a number of occurrences of an event during an existing activation of the first state associated with the temporal logic operator. A state transition from the first state to a second state may be executed based on the value of the temporal logic operator. The second state may be set as the active state.

  • Publication number: 20080243407
    Abstract: Methods, systems and mediums are disclosed for aligning mass spectrometry data before the analysis of the mass spectrometry data. The mass spectrometry data may be received from a mass spectrometry machine, and re-sampled using a smooth warping function. To estimate the warping function, a synthetic signal is build using, for example, Gaussian pulses centered at a set of reference peaks. The reference peaks may be designated by users or calculated after observing a group of spectrograms. The synthetic signal is shifted and scaled so that the cross-correlation between the mass spectrometry data and the synthetic signal reaches its maximum value.

  • Patent number: 7428737
    Abstract: A method and apparatus executes an automated approach allowing access to a standard shared library without requiring the user to create a custom interface definition for library functions that a user wants to access dynamically using a software application. In accordance with one implementation, in an electronic device, a method of accessing a library function from a dynamic environment includes the step of processing a header file of the library function to create an interface to the library function. The interface to the library function is created in the dynamic environment. The user can invoke the process by calling the function from the shared library, and the automated process takes the necessary steps to execute the function.
