摘要： A snapshot of an application executing on a processor is taken in response to detecting an assertion in a running application. The assertion is evaluated based on the snapshot asynchronously while allowing the application to continue executing. The results of the assertion evaluation are returned to the application.

摘要： A method is disclosed that includes tracking untrusted inputs through an executing program into a sink, the tracking including maintaining context of the sink as strings based on the untrusted inputs flow into the sink. The method also includes, while tracking, in response to a string based on an untrusted input being about to flow into the sink and a determination the string could lead to an attack if the string flows into a current context of the sink, endorsing the string using an endorser selected based at least on the current context of the sink, and providing the endorsed string to the sink. Computer program products and apparatus are also disclosed.

摘要： Detecting defects in deployed systems, in one aspect, identify one or more monitoring agents used in a computer program. Total execution metric of the computer program and execution metric associated with the one or more monitoring agents are measured and the measure execution metric is compared with a specified overhead criteria. The execution of the one or more monitoring agents is adjusted based on the comparing step while the computer program is executing to meet the specified overhead criteria.

摘要： There are provided methods for single-owner multi-consumer work queues for repeatable tasks. A method includes permitting a single owner thread of a single owner, multi-consumer, work queue to access the work queue using atomic instructions limited to only a single access and using non-atomic operations. The method further includes restricting the single owner thread from accessing the work queue using atomic instructions involving more than one access. The method also includes synchronizing amongst other threads with respect to their respective accesses to the work queue.

摘要： Given a program P, a specification S, and an abstraction function α, verification determines whether P satisfies the specification S under the abstraction α. If not, a trace T that violate the specification is selected, and either the abstraction α is refined or a constraint that avoids the trace T is computed and added to a set of constraints. The set of constraints are used to modify the program P.
摘要翻译： 给定程序P，规范S和抽象函数α，验证确定P是否满足抽象α下的规范S. 如果没有，则选择违反规范的跟踪T，并且对抽象α进行细化，或者计算避免跟踪T的约束并将其添加到一组约束。 该组约束用于修改程序P.
