20080276238 | Use of Metrics to Control Throttling and Swapping in a Message Processing - A system and method of using metrics to control throttling and swapping in a message processing system is provided. A workload status of a message processing system is determined, and the system polls for a new message according to the workload status. The message processing system identifies a blocked instance and calculates an expected idle time for the blocked instance. The system dehydrates the blocked instance if the expected idle time exceeds a predetermined threshold. | 11-06-2008 |
20090307652 | AUTOMATIC MODEL-SPECIFIC DEBUGGER EXTENSIONS - Extensions to a debugger are identified in a debugger database which is read automatically when the debugger loads. The debugger watches for trigger events in its execution environment and optionally for load conditions in a debuggee program's internal state. If a trigger event occurs and a load condition is met, then the debugger automatically loads an extension for use. Some extensions provide debugging routines that are specifically designed to support debugging of applications which use a specific programming model. | 12-10-2009 |
20090307663 | DEBUGGING SUPPORT FOR TASKS IN MULTITHREADED ENVIRONMENTS - A debugger enhancement provides a debug-task-provider interface whose implementation includes routines designed to support debugging of programs that contain tasks written for a specific programming model. Task creation hierarchies, individual task properties, resource dependencies, synchronization dependencies, and other information can be made accessible during debugging, through a model-independent interface. In a multithreaded environment, a mapping between tasks and threads is also available. | 12-10-2009 |
20100199265 | PROGRAM DEBUGGING WITH DYNAMICALLY INSERTED INSTRUMENTATION - The present disclosure simplifies programming debugging by dynamically injecting debugger compiled instrumentation into the debuggee process such that the debuggee process executes the instrumentation without executing the debugger. In one example method, the debugger controls compiling a description of the instrumentation as an instrumentation method. The debugger can then write the instrumentation method into the debuggee. The debuggee can save the state of a target method of the debuggee process at a predetermined location. The debuggee process calls the instrumentation method from the debuggee. In addition, the state of the target method can be restored and the resumed from the predetermined location after the instrumentation method executes. | 08-05-2010 |
20100235815 | SIMULTANEOUSLY DISPLAYING MULTIPLE CALL STACKS IN AN INTERACTIVE DEBUGGER - Visual representations of multiple call stacks in a parallel programming system include a stack segments graph constructed by coalescing data from multiple stacks. The graph has nodes that represent stack segments and has arcs between adjacent segments. Similar stack frames are represented by the same node. In a stack prefix view of the graph, arcs are directed from a node representing stack frames to a node representing subsequently executed stack frames. In a method-centered view, an arc is shown between a node representing stack frames of a selected method and a node representing adjacent stack frames. The graph can be based on call stacks of all tasks or all threads, or based on call stacks of tasks or threads flagged by a user. Stack frame, thread, and/or task details are also displayed. | 09-16-2010 |
20120124426 | DEBUGGING IN A CLUSTER PROCESSING NETWORK - A technology is described for debugging in a cluster processing network. A scheduler can dispatch a process that is part of the cluster job for execution. Further, a compute node can be used to execute the process dispatched by the scheduler to the compute node. A debugger can be activated in response to an unhandled suspension event in the process on the compute node. In addition, the debugger can send notification messages regarding the unhandled suspension event. A job monitor can receive a notification from the debugger that an unhandled suspension event has occurred. The notification can be displayed to a user via the job monitor. | 05-17-2012 |
20120124504 | DEBUGGING IN A MULTI-PROCESSING ENVIRONMENT - Technology is described for debugging in a multi-processor environment. An example system can include a plurality of process icons representing processes executing on compute nodes. A plurality of relationship arc icons between the process icons can represent messages being sent between source processes and destination processes on the compute nodes. A tabular display control can have rows to display attributes for relationship arc icons representing the messages being sent. In addition, a grouping module can be used to identify groups of messages that are related and to highlight relationship arc icons which are part of a group. | 05-17-2012 |
20120159444 | FUSING DEBUG INFORMATION FROM DIFFERENT COMPILER STAGES - The present invention extends to methods, systems, and computer program products for fusing debug information from different compiler stages. Embodiments of the invention fuse debug information from a plurality of different compile stages in a code generation process into a single set of debug information. The single set of debug information maps directly between instructions and symbols (e.g., source code) input to a first compile stage and instructions and symbols (e.g., machine code) output from a last compile stage. | 06-21-2012 |
