摘要： A method and apparatus for creating a compressed trace for a program, wherein events are compressed separately to provide improved compression and tracing. A sequence of events for a program is selected, and a sequence of values is then determined for each of the selected events occurring during an execution of the program. Each sequence of values is then compressed to generate a compressed sequence of values for each event. These values are then ordered in accordance with information stored in selected events (such as for example, branch events), where the ordered values correspond to the trace.

摘要： During runtime of a binary program file, streams of instructions are executed and memory references, generated by instrumentation applied to given ones of the instructions that refer to memory locations, are collected. A transformation is performed, based on the executed streams of instructions and the collected memory references, to obtain a table. The table lists memory events of interest for active data structures for each function in the program file. The transformation is performed to translate memory addresses for given ones of the instructions and given ones of the data structures into locations and variable names in a source file corresponding to the binary file. At least the memory events of interest are displayed, and the display is organized so as to correlate the memory events of interest with corresponding ones of the data structures.

摘要： A method for application performance data collection includes steps or acts of: customizing a performance tool for collecting application performance data of an application; modifying the application by inserting the performance tool while the application does not need to be rebuilt from the source; executing the application; and collecting the application execution performance data such that only interesting data is collected. Customizing the performance tool proceeds by implementing at least one configurable tracing function that can be programmed by the user; compiling the function(s) into an object file; and inserting the object file into the performance tool using binary instrumentation.

摘要： A method, system and computer program product are disclosed for maintaining data coherence, for use in a multi-node processing system where each of the nodes includes one or more components. In one embodiment, the method comprises establishing a data domain, assigning a group of the components to the data domain, sending a coherence message from a first component of the processing system to a second component of the processing system, and determining if that second component is assigned to the data domain. In this embodiment, if that second component is assigned to the data domain, the coherence message is transferred to all of the components assigned to the data domain to maintain data coherency among those components. In an embodiment, if that second component is assigned to the data domain, the first component is assigned to the data domain.

摘要： A memoryless communications adapter for communicating between the nodes of a distributed parallel computer network, each node including a non-shared program memory coupled to the memoryless communications adapter which interfaces the network. An embodiment of the present invention advantageously provides an adapter that can manipulate queues and matching tables efficiently in hardware and provide a high-level object view of queues and matching in the context of communication between nodes. Preferably, the Queue manipulation logic, Match Table manipulation logic and the Sequence Table manipulation logic are implemented in the adapter hardware which does not keep any state or resources in it that depend on the size of the system or the number of queues/tables instantiated. The actual states of these objects may be kept in the program memory, so that the adapter hardware is memoryless.

摘要： A pointer is for pointing to a next-to-read location within a stack of information. For pushing information onto the stack: a value is saved of the pointer, which points to a first location within the stack as being the next-to-read location; the pointer is updated so that it points to a second location within the stack as being the next-to-read location; and the information is written for storage at the second location. For popping the information from the stack: in response to the pointer, the information is read from the second location as the next-to-read location; and the pointer is restored to equal the saved value so that it points to the first location as being the next-to-read location.
