Abstract: Detecting optimization opportunities is enabled by utilizing a trace of a target concurrent computer program and determining a relation between data objects accessed during the tracked execution. The relation may be stored in a Temporal Relation Graph (TRG), in an extended-TRG or another data structure. The relation may be affected by temporally-adjacent accesses to data objects. The relation may further be affected by accesses to data objects performed during critical sections of the target program.

Abstract: Methods, systems, and computer program products for applying actions during server system processing. Functional processing blocks where actions may be applied to a service request are identified. actions are dynamically associated with functional processing blocks. During execution of a functional processing block, a check is performed to determine whether an action is associated with the functional processing block. If an action is associated with a functional processing block, the action is applied during the functional processing block's execution. An evaluation may be performed to determine if an action should be applied before or after the functional processing block. The server system may comprise an XML data repository, providing access to XML data, based on identity information which is received with a client system request. A portion of the server system may be described in accordance with an XML schema.

The captured performance metrics include throughput and response time of remote method invocation, object serialization, and transport. The performance metrics are captured per remote method invocation. Performance metrics may be sent to a processing unit for storage, analysis, and correlation.

A tree having nodes to represent the stack trace elements is created such that that the child elements branch from the parent/child elements or the parent elements, and the parent/child elements branch from the parent elements.

Abstract: A method to provide effective control and data flow information in an Intermediate Representation (IR) form. A Path Sensitive single Assignment (PSA) IR form with effective and explicit control and data path information supports control flow sensitive optimizations such as path sensitive symbolic substitution, array privatization and speculative multi threading. In the definition of PSA form, besides defining new versioned variables, the gamma functions keep control path information. The gamma function in PSA form keeps the basic attribute of SSA IR form and only one definition exists for each use. Therefore, all existing Single Static Assignment (SSA) IR form based analysis can be applied in PSA form. The gamma function in PSA form keeps all essential control flow information and eliminates unnecessary predicates at the same time.

Abstract: Techniques are provided for determining consequences of an injected fault on a system running a given application program or operating system, in order to measure the software impact of a hardware soft error on the application program/operating system. The application program software is emulated instruction-by-instruction, where source operands are randomly modified before an instruction is executed, and destination operands are randomly modified after an instruction is executed, in order to mimic hardware soft errors. In addition, a program counter is randomly modified after execution of a branch instruction. The resulting consequences of such modifications are monitored such that a fault of an instruction being executed is modeled in order to determine a soft error rate (SER) for a software application program or operating system.
