Abstract: Systems and methods for data analysis include constructing patient traces as a set of medical events for each patient of a patient population, the patient population being segmented based on patient outcomes. Medical events in one or more of the patient traces are reduced to provide processed patient traces. The processed patient traces are clustered to identify a cluster of patient traces. A process model is mined, using a processor, representing an aggregation of treatment pathways in the patient traces from the cluster. Patterns from patient traces are identified that are discriminative of patient outcomes. At least one of the patterns is represented with respect to the process model to identify treatment pathways correlated with the patient outcomes.

Abstract: Aspects of the present invention provide a tool for analyzing and remediating an update-related failure. In an embodiment, a failure state of a computer system that has been arrived at as a result of an update is captured. A semantic diff that includes the difference between the failure state and at least one of an original state or a completion state is then computed. This semantic diff is transformed into a feature vector format. Then the transformed semantic diff is analyzed to determine a remediation for the update. Failure and/or resolution signatures can be constructed using the semantic diff and contextual data, and these signatures can be used in comparison and analysis of failures and resolutions.

Abstract: Compiling source code for debugging, including: receiving, by an optimizing compiler from a debugger, a user specification of preferred breakpoint locations in the source code; compiling, by the optimizing compiler, the source code, wherein compiling includes inserting a snapshot at one or more of the preferred breakpoint locations, and recording the location of each inserted snapshot; and providing, to the debugger by the optimizing compiler, the recorded locations of each inserted snapshot along with the compiled source code.

Abstract: A method for providing a real time view of heterogeneous enterprise data of operational systems includes capturing streams of operational events in real time, combining the events with contextual data, and materializing a resulting view. The resulting view includes a dynamically defined view of the stream of events and provides visibility into a current state of the operational system. A view snapshot is continuously incrementally updated by a view maintenance engine as a stream of rows. The views are used to evaluate a business rule. An alert is fired when a business rule holds true. To enable the view in a view engine, a SQL string characterizing the view is parsed into a parse tree, which is normalized to form a query graph. The query graph is then optimized to obtain a query plan, which is compiled into an operator graph. Queries are executed based upon the operator graph.

Abstract: Aspects of the present invention provide a solution for passively monitoring a computer system. In an embodiment, a virtual server is accessed by an indexing agent that is contained in an indexing appliance. The virtual server is located on a physical server and is one of a plurality of virtual system instances on a common physical server. The indexing appliance is separate from the virtual server and, as such, the indexing agent is not executed within the virtual server, itself. The indexing agent retrieves a virtual image of the virtual server and indexes the virtual image to extract features indicative of changes in the virtual server. These features are analyzed to perform passive monitoring of the virtual server. Since the indexing appliance is separate from the virtual server for which passive monitoring is being performed, the indexing agent can perform the retrieving and the indexing without utilizing agents executing within the virtual server.

Abstract: A graphical user interface for a Gantt chart map display (100) includes a list of projects (214), a corresponding activity timeline reflecting activity for each project, and a control (210) at a side or bottom area of the Gantt chart map display for manipulating date ranges viewable in the viewable area. The GUI further includes a selected date range control (204) providing a high level view (202) of the corresponding activity timeline displayed in the viewable area (212) above and can provide a high level view of corresponding activity beyond the scrollable view. A dynamic set of controls (205 and 206) enables preset filtered views of the Gantt chart with preset time frames such as days, weeks, months and years or predetermined date ranges entered by a user. The preset filtered view can also automatically re-sort and scale content on the Gantt chart into a viewable area to reduce scrolling.
